Electrical Performance

Inverter Topology 

The Global LF inverter/charger is built according to the following topology:

• Invert: Full Bridge Topology
• Charge: Isolated Boost Topology

It works bi-directionally: in one direction it converts DC power from the battery to AC power (Inverter Mode) and in the other direction it converts external AC power to DC power to charge the batteries (AC Mode). The same power components are used in both directions, resulting in high-energy transfer efficiency with fewer components.

Please note that the inverter/charger can only work in one direction at one time (i.e. it cannot work as an inverter and as a charger at the same time). When operating in inverter mode, the direct current (DC) that enters the inverter from the batteries is filtered by a large input capacitor and switched “On” and “Off” by the Metal Oxide Silicon Field Effect Transistors (MOSFET) at a rate of 50 Hz or 60Hz. In this step, the DC is converted to low voltage synthesized sine wave AC using an H-bridge configuration and high frequency PWM (Pulse Width Modulation) technique. It is then directed into the transformer which steps the low AC voltage up to 230 or 120 volts. The unit has a 16bit, 4.9MHZ microprocessor to control the output voltage and frequency as the DC input voltage and/or output load varies. Because of high-efficiency MOSFETs and the heavy transformers, it outputs PURE SINE WAVE AC with an average THD of 10% (min 3%, max 20% under full linear loads) depending on the load connected and battery voltage. The peak DC to AC conversion efficiency of the Global LF series is >88%.

Don’t parallel the AC output of the inverters to increase power capacity as they have no stacking functionality.

Overload Capacity 

The Global LF series inverters have high overload capacities, making them ideal to handle demanding loads.

• For 110% < Load < 125% (±10%): No audible alarm for 14 minutes, beeps 0.5s every 1s in the 15th minute, and Fault (Turn off) after the 15th minute.
• For 125% < Load < 150% (±10%): Beeps 0.5s every 1s and Fault (Turn off) after 1 minute.
• For 300% ≧ Load > 150% (±10%): Beeps 0.5s every 1s and Fault (Turn off) after 20s.

Caution: After the inverter is switched on, it takes time for it to self-diagnose and be ready to deliver full power. Hence, always switch on the load(s) after a few seconds of switching on the inverter. Avoid switching on the inverter with the load already switched on. This may prematurely trigger the overload protection. When a load is switched on, it may require an initial higher power surge to start. Hence, if multiple loads are being powered, they should be switched on one by one so that the inverter is not overloaded by the higher starting surge if all the loads are switched on at once.

Aims Power Wave Inverter Charger PICOGLF60W AC Charger

The Global LF Series is equipped with an active PFC (Power Factor Corrected) multistage battery charger. The PFC feature is used to control the amount of power used to charge the batteries in order to obtain a power factor as close as possible to 1.

Unlike other inverters whose max charging current decreases according to the input AC voltage, the Global LF series charger is able to output max current as long as the input AC voltage is in the range of 164-243VAC (95-127VAC for 120V model), and AC frequency is in the range of 48-54Hz (58-64Hz for 60Hz model).

The Global LF series inverter has a very rapid charge current available, and the max charge current can be adjusted from 0%-100% via a liner switch to the right of the battery type selector. This will be helpful if you are using our powerful charger on a small capacity battery bank. Fortunately, the liner switch can effectively reduce the max charging current to 20% of its peak. Choosing “0” in the battery type selector will disable the charging function.

Caution: Turn the charge current control switch gently to avoid breakage due to over-turning.

There are 3 charging stages:

• Bulk Charging: (fast charge LED solid) This is the initial stage of charging. While Bulk Charging, the charger supplies the battery with controlled constant current. The charger will remain in Bulk charge until the Absorption charge voltage (determined by the Battery Type selection) is achieved. A software timer will measure the time from A/C start until the battery charger reaches 0.3V below the boost voltage, then take this time as T0 and T0×10 = T1.
• Absorb Charging: (fast charge LED blinking) This is the second charging stage when the fast charge LED is flashing and begins after the absorb voltage has been reached. Absorb Charging provides the batteries with a constant voltage and reduces the DC charging current in order to maintain the absorb voltage setting. In this period, the inverter will start a T1 timer; the charger will keep the boost voltage in Boost CV mode until the T1 timer has run out. Then drop the voltage down to the float voltage. The timer has a minimum time of 1 hour and a maximum time of 12 hours.

• Float Charging: (float charge LED solid) The third charging stage occurs at the end of the Absorb Charging time. While Float charging, the charge voltage is reduced to the float charge voltage (determined by the Battery Type selection*). In this stage, the batteries are kept fully charged and ready if needed by the inverter. If the A/C is reconnected or the battery voltage drops below 12Vdc/24Vdc, the charger will restart the above cycle. If the charge maintains the float state for 10 days, the charger will deliberately reset the cycle to protect the battery.

  

Battery type selector

De-sulphation

The de-sulphation cycle (switch position 8) is a very dangerous setting if you do not know what you are doing. Before attempting to use this cycle you must clearly understand what it does and when and how you would use it.

Causes of Sulphation

Sulphation occurs primarily due to infrequent use of batteries or if the batteries have been discharged to a level where they will not accept a charge. When batteries are left in a discharged state for an extended period, lead sulfate crystals form on the battery plates, preventing efficient charging. This cycle involves applying a high voltage charge to break down the sulphated crust, thereby allowing the plates to clean up and accept a charge once again.

Charging Depleted Batteries

The Global LF series inverter allows for start-up and through power with depleted batteries. For 12VDC models, if the battery voltage drops below 10V and the inverter remains connected and switched on, it can charge the battery when qualified AC inputs are present, as long as the voltage does not fall below 9V. If the voltage drops below 9V, the inverter will not charge the battery if disconnected or switched off because the CPU loses memory during this process. For 24VDC and 48VDC models, multiply all voltages by 2 and 4, respectively.

The charging capacity will go to peak charge rate in about 3 seconds. This may cause a generator to drop frequency, making the inverter transfer to battery mode.
It is recommended to gradually put the charging load on the generator by switching the charging switch from min to max. Together with the 15s switch delay our inverter gives the generator enough time to spin up. This will depend on the size of the generator and rate of charge. As a general rule, the Bulk Charging.

Current should be limited to 30% of the capacity of the battery bank. Higher charging current may be used if permitted by the battery manufacturer.

Caution: Please use a small jeweler’s style flat-head screwdriver to turn the charge current control switch gently to avoid breakage due to over-turning. To guarantee the best performance of AC charger when the AC input is from a generator, the standby generator should be of at least 150% higher capacity than the inverter.
Warning! Operation with an under-rated generator or generator with unqualified wave form may cause premature failure which is not under warranty.

Transfer

• Swift Power Transfer: The inverter automatically transfers from Standby mode to Invert mode when AC power falls below the low AC voltage trip voltage, with a transfer time of approximately 10 milliseconds.
• Synchronized Power Transfer: The inverter locks onto the frequency and phase of the input shore power/generator power before making a smooth transfer at the zero voltage point.
• Transfer Delay: There is a 15-second delay to allow generators to stabilize voltage and frequency before transferring to generator power.

Auto Frequency Adjust

The factory default configuration for inverters sold in American market is 60Hz. If the output frequency needs to be changed this is done by putting in a valid input Power Source to the inverter’s input lines. Once the inverter validates the input, the output will automatically change.
NOTE: The inverter will output factory set frequency of 60Hz controlled with DIP switch #4 position.

Power Saver Mode

There are 2 different working statuses for our Global LF inverter: “Power On” and “Power Off”.
When the power switch is in “Unit Off” position, the inverter is powered off.

Working Statuses

There are 2 different working statuses for our Global LF inverter: "Power On" and "Power Off".

• When the power switch is in the "Unit Off" position, the inverter is powered off.
• When the power switch is turned to either "Power Saver Auto" or "Power Saver Off", the inverter is powered on.

The power saver function is designed to conserve battery power when AC power is not or rarely required by the loads. In this mode, the inverter pulses the AC output looking for an AC load (i.e., electrical appliance). Whenever an AC load (greater than 50 watts) is turned on, the inverter recognizes the need for power and automatically starts inverting, and the output goes to full voltage. When there is no load (or less than 50 watts) detected, the inverter automatically goes back into search mode to minimize energy consumption from the battery bank.

In "Power Saver On" mode, the inverter will draw power mainly in sensing moments, thus the idle consumption is significantly reduced. The inverter will detect a load for 250ms every 3 seconds (DIP switch #3 position 1).

Note: The minimum power of a load to take the inverter out of sleep mode (Power Saver On) is 50 Watts. The Global LF Series is designed with extremely low idle power consumption which is only a mere 0.8-1.8% of its rated power.

Global LF Series Idle Power Consumption (in Watts)

When in the search sense mode, the green power LED will blink and the inverter will make a ticking sound. At full output voltage, the green power LED will light steadily and the inverter will make a steady humming sound. When the inverter is used as an "uninterruptible" power supply, the search sense mode or "Power Saver On" function should be defeated.

Exceptions

Some devices when scanned by the load sensor cannot be detected. Small fluorescent lights and inductive loads are the most common examples. (Try altering the plug polarity by turning the plug over.) Some computers and sophisticated electronics have power supplies that do not present a load until line voltage is available. When this occurs, each unit waits for the other to begin. To drive these loads, either a small companion load must be used to bring the inverter out of its search mode, or the inverter may be programmed to remain at full output voltage (Power On mode).

Protections

The Global LF series inverter is equipped with extensive protections against various harsh situations/faults. These protections include:

• AC input over voltage protection/AC input low voltage protection
• Low battery alarm/high battery alarm
• Over temperature protection/over load protection
• Short circuit protection (1s after fault)
• Back feeding protection

When over temperature/over load occurs, after the fault is cleared, the master switch needs to be reset to restart the inverter. The low battery voltage trip point can be customized from a defaulted value of 10VDC to 10.5VDC through SW1 on the DIP switch. The inverter will go to over temp protection when the heat sink temp. ≥105ºC (221℉), and go to fault (shutdown output) after 30 seconds. The switch needs to be reset to activate the inverter.

The Global LF series inverter has back feeding protection which avoids presenting an AC voltage on the AC input terminal in inverter mode. After the reason for the fault is cleared, the inverter needs to be reset to start working.

Remote Control

Apart from the switch panel on the front (or top) of the inverter, an extra switch panel connected to the RJ11 port at the DC side of the inverter through a standard telephone cable can also control the operation of the inverter (sold separately Part # PICGLFREMOTE). If an extra switch panel is connected to the inverter via the "remote control port", together with the panel on the inverter case, the two panels will be connected and operated in parallel. Whichever first switches from "Off" to "Power saver off" or "Power saver on", it will power the inverter on. If the commands from the two panels conflict, the inverter will operate according to the following priority: Power saver on > Power saver off > Power off. Only when both panels are turned to the "Unit Off" position, will the inverter be powered off. The max length of the cable is 60 feet.

The Remote LCD will display the following content:

• Input AC Voltage
• Output AC Voltage
• Battery Voltage
• Output Frequency
• Output Load
• Work Mode
• Alarm Fault
• Battery Capacity

A push button on the left of the panel can be used to turn off the LCD screen and save 0.1A current draw on the battery. 

Greeting message of "Welcome to AIMS POWER".

• AC Status & Input Voltage: "AC: abnormal" is displayed when AC input is not qualified.
• Output Voltage/Frequency and Output Current (in percentage) in inverter mode
• Battery voltage

Note: When the inverter is in Battery Priority mode, finishes a complete charging cycle, and switches to inverter mode "AC: abnormal" will be displayed. In AC mode, the LCD will not display the status of the AC load.

WARNING: Never cut the telephone cable when the cable is attached to the inverter and the battery is connected to the inverter. Even if the inverter is turned off, it will damage the remote PCB inside if the cable is short-circuited during cutting.

FAN Operation

For 1-3KW models, there is one multiple controlled DC fan which starts to work according to the below logic.
For 4-6KW models, there is one multiple controlled DC fan and one AC fan. The DC fan will work in the same way as the 1-3KW models, while the AC fan will work once there is AC output from the inverter. So when the inverter is in power saver mode, the AC fan will work from time to time in response to the pulse sent by the inverter in power saver mode.
The Operation of the DC fan at the DC terminal side is controlled by the following logic:

Allow at least 12 inches of clearance around the inverter for air flow. Make sure that the air can circulate freely around the unit. Fan noise level <60db at a distance of 3 feet

DIP Switches

On the DC end of inverter, there are 5 DIP switches which enable users to customize the performance of the device.

Low Battery Trip Volt (SW1)

Deep discharge of the lead acid battery leads to high losses in capacity and early aging. In different applications, a different low voltage disconnection level is preferred. For example, for solar applications, users may intend to have less Depth of Discharge (DOD) to prolong the battery life cycle. While for mobile applications, users may intend to have more DOD to reduce battery capacity and on-board weight.

For 12VDC models, the Low Battery Trip Volt is set at 10.0VDC by default. It can be customized to 10.5VDC using SW1. This is to prevent batteries from over-discharging while there is only a small load applied on the inverter.

Multiply by 2 for 24VDC, multiply by 4 for 48VDC.

AC Input Range (SW2)

There are different acceptable AC input ranges for different kinds of loads. For some relatively sensitive electronic devices, a narrow input range of 184-253VAC (100-135V for 120VAC model) is required to protect them. While for some resistive loads which work in a wide voltage range, the input AC range can be customized to 154-264VAC (90-135V for 120VAC model), this helps to power loads with the most AC input power without frequent switches to the battery bank.

In order to make the inverter accept dirty power from a generator, when the SW2 is switched to position “1”, the inverter will bypass an AC input with a wider voltage and frequency (40-70Hz for 50Hz/60Hz). Accordingly, the AC charger will also work in a wider voltage and frequency range (42-68Hz for 50Hz/60Hz). This will avoid frequent switches between battery and generator. But some sensitive loads will suffer from the low quality power.

The pros and cons should be clearly realized.

Power Saver Override ON/OFF (SW3)

The factory default for SW3 is Position 0. Position 1 will allow the Power Save feature of the inverter to detect a load for 250ms every 3 seconds. If a load is detected, the inverter will output AC Power. If SW3 is moved to Position 0, this will prevent the sense pulse from being sent out, even if the inverter is in Power Save mode via the Main Power switch. No power will be output unless Shore Power input is present. Only then will the battery charger and AC throughput operate when SW3 is in Position 0.

Frequency Switch (SW4)

The output frequency of the inverter can be set at either 50Hz or 60Hz by SW4.

AC/Battery Priority (SW5)

Our inverter is designed with AC priority by default. This means, when AC input is present, the battery will be charged first, and the inverter will transfer the input AC to power the load. Only when the AC input is stable for a continuous period of 15 days will the inverter start a battery inverting cycle to protect the battery. After one normal charging cycle, AC throughput will be restored.

The AC Priority and Battery Priority switch is SW5. When you choose battery priority, the inverter will invert from the battery despite the AC input. Only when the battery voltage reaches the low voltage alarm point (10.5V for 12V, 21VDC for 24VDC, 42VDC for 48VDC) will the inverter transfer to AC Input, charge the battery, and switch back to the battery when the battery is fully charged. This function is mainly for wind/solar systems using utility power as backup.

Note: In battery priority mode, when qualified AC inputs for the first time and the battery voltage is below 12.5VDC (12.5VDC for 12VDC, 25VDC for 24VDC, 51VDC for 48VDC), the inverter will go into battery priority mode only after a cycle of bulk charging and absorb charging is finished. The inverter will not go into float charging mode.

Auto Generator Start

The inverter can start up a generator when the battery voltage drops. When the inverter goes to low battery alarm, it can send a signal to start a generator and turn the generator off after the battery charging is finished.

The auto gen start feature will only work with generators that have automatic starting capability. The generator must have start and stop controls (i.e., an electric starter and electric choke for gasoline units), and the safety sensors to be able to start and stop automatically. There is an open/close relay that will short circuit the positive and negative cables from a generator start control. The input DC voltage can vary, but the max current the relay can carry is 16Amp.

The Auto Generator Start terminal pins are not polarized. In addition, these two pins can also be used as dry contacts to send out a “Low Battery Voltage” signal to an external alarm device. Use 18 AWG speaker wire for this application.

Other Features

Battery Temperature Sensing

Applying the proper charge voltage is critical for achieving optimum battery performance and longevity. The ideal charge voltage required by batteries changes with battery temperature. The battery temperature sensor allows the charge controller to continuously adjust the charge voltage based on the actual battery temperature. Temperature compensation of charge voltage assures that the battery receives the proper charge voltage as battery temperature varies.

The entire line of Global LF inverters is equipped with Battery Temperature Sensing for increased charging precision. It sends precise information to the charger, which automatically adjusts voltage to help ensure a full battery charge depending on the ambient temperature of your battery installation. When the battery voltage is over 104℉, it will reduce the charging voltage by 0.1Vdc with every degree of temperature rise.

AIMS recommends that you install Battery Temperature Sensors on all banks to protect your batteries and to provide optimal charging of each bank. The battery temperature sensor mounts on the side of a battery using silicon or electrical tape.

Battery Voltage Recovery Start

After low battery voltage shut off (10V for 12V model or 20V for 24V model or 40V for 48V model), the inverter is able to restore operation after the battery voltage recovers to 13V/26V/52V (with power switch still in the “On” position). This function helps to save users extra labor to reactivate the inverter when the low battery voltage returns to an acceptable range in renewable energy systems. The built-in battery charger will automatically reactivate as soon as city/generator AC has been stable for 15 seconds.

WARNING Never leave the loads unattended; some loads (like a heater) may cause accidents in such cases. It is better to shut everything off after low voltage trip than to leave your load on, due to the risk of fire.

Conformal Coating

AIMS Power's entire line of Global LF inverters has been processed with a conformal coating on the PCB, making it water, rust, and dust resistant as well as corrosion resistant. While these units are designed to withstand corrosion from salty air, they are not splash-proof.

Automatic Voltage Regulation

The automatic voltage regulation function is for the full series of APS Pure Sine Wave Inverter/Charger. Instead of simply bypassing the input AC to power the loads, the APS series inverter stabilizes the input AC voltage to a range of 230V/120V ±10%. Connected with batteries, the APS Series inverter will function as a UPS with a max transfer time of 10 ms. With all of the unique features our inverter provides, it will bring you long-term trouble-free operation.

Unpacking and Inspection

Carefully remove the inverter/charger from its shipping package and inspect all contents. Verify the following items are included:

• The PICOGLF Inverter/Charger
• Red and black DC terminal covers
• AC terminal block cover with two Phillips screws
• Two flange nuts and 4 Phillips screws (installed on the DC terminals)
• PICOGLF Series Owner’s Manual

If items appear to be missing or damaged, contact our authorized dealer or us. If possible, keep your shipping box to protect your inverter from damage if it ever needs to be returned for service. Save your proof-of-purchase as a record of your ownership; it will also be needed if the unit requires warranty work.

Follow all local regulations to install the inverter. Install the equipment in an indoor location that is dry, clean, cool, and well-ventilated.

• Working temperature: -14℉ to 122℉
• Storage temperature: 40℉ to 158℉
• Relative Humidity: 0% to 95%, non-condensing
• Cooling: Forced air

CAUTION: Some models are heavy. Use proper lifting techniques during installation to prevent personal injury.

WARNING: The inverter should not be installed in an area that allows dust, fumes, insects, or rodents to enter or block the inverter’s ventilation openings. This area must also be free from any risk of condensation, water, or any other liquid that can enter or fall on the inverter.

The entire line of inverters has been processed with a conformal coating on the PCB, making it water, rust, and dust-resistant. While these units are designed to withstand corrosion from salty air, they are not splash-proof. The inverter’s life is uncertain if used in such environments, and inverter failures under these conditions are not covered under warranty.

Installation Tools / Materials

Tools 

You will need the following tools to install the Global LF series inverters and the battery temperature sensor:

• Wire stripper
• Crimping tools for fastening lugs and terminals on DC cables
• Phillips screwdriver: #2
• Slot screwdriver (¼" wide blade max.)
• Needle-nose pliers
• Wrench for DC terminals: 9/16"

Materials 

You will need the following materials to complete your installation:

• Correct size DC battery cables
• Terminals and/or crimp connectors for DC cables
• Copper wire for DC grounding: No. 8 AWG
• Terminal or crimp connector for DC grounding cable (for 1/4" stud size)
• AC output and input wire
• If the AC ground wire is stranded, each ground wire requires a ring terminal
• Six 1/4"–20 1.25" length steel screws or bolts to mount the inverters

DC Wiring

It is recommended that the battery bank be kept as close as possible to the inverter. The following is a suggested wiring option for 12 feet of DC cable. Follow the minimum wire size. If the DC cable is longer than 12 feet, increase the size of the cable to reduce voltage drop.

Battery cables must be crimped (or preferably, soldered and crimped) copper compression lugs unless aluminum mechanical lugs are used. Soldered connections alone are not acceptable. High-quality, UL-listed battery cables are available. These cables are color-coded with pressure crimped, sealed ring terminals.

Battery terminal must be clean to reduce the resistance between the DC terminal and cable connection. A buildup of dirt or oxidation may eventually lead to the cable terminal overheating during periods of high current draw. Use a stiff wire brush and remove all dirt and corrosion from the battery terminals and cables.

Reducing RF interference 

To reduce the effect of radiated interference, twist the DC cables. To further reduce RF interference, shield the cables with sheathing, copper foil, or braiding.

Taping battery cables together to reduce inductance 

Do not keep the battery cables far apart. If it is not convenient to twist the cables, keep them taped together to reduce their inductance. Reduced inductance of the battery cables helps to reduce induced voltages, thereby reducing ripple in the battery cables and improving performance and efficiency.

Warning: The torque rating range for DC terminals is 12.5NM-20.5NM (9.25-15.19 pound-foot), and the suggested torque rating is 17NM (12.6 pound-foot). Over-torquing may break the bolt.

Equipment Damage 

The inverter is not reverse polarity protected. Reversing the battery polarity on the DC input connections will cause permanent damage to the inverter, which is not covered under warranty. Always check polarity before making connections to the inverter. The inverter contains capacitors that may produce a spark when first connected to the battery. Do not mount in a confined compartment with a vented battery or gases. Ensure the inverter is off before disconnecting the battery cables and that AC power is disconnected from the inverter input.

WARNING: Do not reverse the polarity! This can totally destroy the unit and void the warranty.

AC Wiring

The AC terminal is rated for wires of 8 AWG to 20 AWG; we recommend using 10 to 8 AWG wire to connect to the AC terminal block. When in AC mode, the AC input power will supply both the loads and AC charger, requiring a thicker wire gauge for AC input. Please consult a qualified electrician about the specific wire gauge required in terms of wire material and inverter power.

There are three different ways of connecting to the terminal block depending on the model. All the wirings are CE compliant. Call our tech support if you are unsure about how to wire any part of your inverter.

Caution: Wiring Option 2 and Wiring Option 3 are only allowed for the following models: PICOGLF50W24V230VS, PICOGLF50W48V230VS, PICOGLF60W24V230VS, PICOGLF60W48V230VS. Please wire all other models according Wiring Option 1.

WARNING: For split phase models, AC input neutral is not required in wiring. Never connect input neutral to output neutral. Damage will result which is not covered under warranty. Always switch on the inverter before plugging in any appliance.

Grounding

Connect an AWG 8 gauge or greater copper wire between the grounding terminal on the inverter and the earth grounding system or the vehicle chassis.

Automatic Neutral-to-Ground Connection

All single-phase 120Vac inverters are equipped with automatic neutral-to-ground switching. These inverters use an internal relay that automatically connects the AC neutral output to the vehicle/boat’s safety ground (bonding it) in Inverter Mode and disconnects it (unbonding it) when connected to a qualified external AC source. 

This design prevents two neutral-to-ground connections from existing simultaneously, thereby preventing an electrical shock hazard between the vehicle/boat’s neutral and the external AC source’s neutral.

Disabling the Automatic Neutral-to-Ground Connection 

In some installations, this feature must be disabled. To accommodate these situations, the automatic neutral-to-ground connection system can be defeated, so it will not bond the neutral in any mode of operation. If you are unsure whether you must disable this feature, please refer to your local code requirements.

There is a section of green wire with the insulated connector on the left side of the AC terminal block. This insulated connector connects the neutral and ground inside the inverter while inverting. Pull the two ends of the insulated connector apart to separate the green wire; this will prevent the neutral and ground from connecting inside this inverter. If possible, use electrical tape to insulate the disconnected ends, move the two ends away from each other, and push them back out of the way. Typically, you would disconnect this connection when connecting to a house panel (after disconnecting city power from it) as a house panel already has the neutral-to-ground bond. In a standalone system or in a vehicle, you would want to keep this connection.

Important Safety Information

WARNING! Before using the Inverter, you need to read and save the safety instructions.

General Safety Precautions

• Do not expose the Inverter to rain, snow, spray, bilge or dust. To reduce risk of hazard, do not cover or obstruct the ventilation openings. Do not install the Inverter in a zero-clearance compartment. Overheating may result. Allow at least 12” of clearance around the inverter for air flow. Make sure that the air can circulate freely around the unit. A minimum air flow of 145CFM is required.
• To avoid risk of fire and electronic shock, make sure that existing wiring is in good electrical condition and that the wire is not undersized. Do not operate the Inverter with damaged or substandard wiring.
• This equipment contains components which may produce arcs and/or sparks. To prevent fire and/or explosion, do not install in compartments containing batteries or flammable materials or in a location which requires ignition protected equipment. This includes any space containing gasoline-powered machinery, fuel tanks, or joints, fittings, or other connections between components of the fuel system. See Warranty for instructions on obtaining service.
• Do not disassemble the Inverter/Charger. It contains no user-serviceable parts. Attempting to service the Inverter/Charger yourself may result in electrical shock or fire. Internal capacitors remain charged after all power is disconnected.
• To reduce the risk of electrical shock, disconnect both AC and DC power from the Inverter/Charger before attempting any maintenance or cleaning. Turning off controls will not reduce this risk.

CAUTION: Equipment damage

• The output side of the inverter’s AC wiring should at no time be connected to public power or a generator. This condition is far worse than a short circuit. If the unit survives this condition, it will shut down until corrections are made. Installation should ensure that the inverter’s AC output is, at no time, connected to its AC input.

Precautions When Working with Batteries

• If battery acid contacts skin or clothing immediately wash with soap and water. If acid enters eyes immediately rinse eyes with running cold water and seek immediate medical attention.
• Never smoke or allow sparks or flames in the vicinity of a battery.
• Do not drop a metal tool on the battery. The resulting spark or short-circuit on the battery will cause an explosion.
• Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a battery. A battery produces a short-circuit current high enough to weld any metal objects and will cause a severe burn.
• To reduce the risk of injury, charge only deep-cycle lead acid, lead antimony, lead calcium gel cell, absorbed mat, LIFEPO4 lithium, or NiCad/NiFe type rechargeable batteries. Other types of batteries may swell or burst causing personal injury and damage.

General Information

The Global LF Series Pure Sine Wave Inverter Charger product line is a combination of an inverter and battery charger with an AC auto-transfer switch into one complete system with a peak conversion efficiency of 88%. It is packed with unique features and it is one of the most advanced inverter chargers on the market today. It features power factor correction, sophisticated multi-stage charging, and pure sine wave output with unprecedentedly high surge capability to meet demanding power needs of inductive loads without damaging the equipment.

When utility AC power cuts off (or falls out of acceptable range), the transfer relay is de-energized and the load is automatically transferred to Inverter mode. Once the qualified AC power is restored the relay is re-energized and the load is automatically reconnected to AC bypass mode. The Global LF Series Inverter is equipped with a powerful four-stage smart charger and includes an auto generator start feature. The overload capacity of the inverter charger products is 300% of continuous output for up to 20 seconds to reliably support tools and equipment.

Another important feature is that the inverter can be easily customized to Battery priority via a DIP switch. This helps to extract maximum power from the battery in renewable energy systems such as solar and wind. The Global LF Series Pure Sine Wave Inverter is suitable for renewable energy systems in work trucks, RVs, marine, and emergency appliances.

To get the most out of the power inverter, it must be operated and maintained properly. Please read the instructions in this manual before installing and operating.

Indicator and Buzzer

Note: The reason for the noise from transformer and/or case.

When in inverter mode sometimes the transformer and/or case of the inverter may vibrate and make noise. If the noise comes from the transformer: According to the characteristics of our inverter, there is one type of load which most likely may cause rattles of the transformer. That is a half wave load: A load that uses only half a cycle of the power. This tends to cause an imbalance of the magnetic field of the transformer, reducing its rated working frequency from 20KHz to, say, maybe 15KHz (it varies according to different loads). In such a case, the frequency of noise falls exactly into the range (200Hz-20KHz) that human ears can hear. The most common load of such kind is a hair drier.

If the noise comes from the case: Normally, when loaded with inductive loads, the magnetic field generated by the transformer keeps attracting or releasing the steel case at a specific frequency. This may also cause noise. Reducing the load power or using an inverter with bigger capacity will normally solve this problem. The noise will not do any harm to the inverter or the loads.
