Assemble

1. The position of Mounting
   First ensure that there is enough space to install the inverter, while the installation location must meet the following requirements
   1. Drying: Do not use water or other liquids dripping on the inverter
   2. Cool: a working environment temperature of the product is 0-40℃, preferably a temperature of 10-25℃, at a temperature as low as possible within this range
   3. Ventilation: There should be a certain distance between inverter and other objects, to avoid blocking the products vents.
   4. Clean: Do install the products in the dusty, wood chips or other particles , If cooling fan is turned on, the particles involved in the inside of the product, thus affecting the normal work.
   5. While inverters and batteries connected, will produce arcs or sparks, so there should not be around flammable objects such as gasoline, alcohol, etc.
2. Assemble the inverter 
   For this big power inverter, because of the heavier weight, preferably mounted on a solid platform, such as floor, table or mounting bracket fine. In order to avoid falling off, platform for supporting the product should can bear the weight of sufficient capacity, and it is good with four screws to secure the product.

Note: In case not connected to the remote box, the product can also be used as a normal modified sine wave inverter as normal.

Using time of battery

1. Current and voltage:
   The battery is used to supply the DC input voltage required by the product, and its rated voltage must be in line with the rated input voltage of the inverter, beyond the input voltage range of the inverter, and the cross connection will cause the product to be under voltage or under voltage protection. At the same time, the battery must provide enough current for inverter, a small capacity battery is not able to drive high power appliances, in this case, usually due to excessive current and battery discharge the battery terminal voltage low, undervoltage protection products appear The simple formula for the battery current is the load power / the battery voltage. As the inverter itself will be part of the loss, so the actual current will be greater than this value of about 10%. For example: the battery voltage is 12VDC, the load power is 400W, then the actual current size of the battery is about 400W÷12Vx110%=37A
2. Battery working time
   The using time of battery depends on battery capacity (AH) and the power of the connected load (W), the calculating method is: Time (hours) =battery capacity (AH) × battery output voltage (V) x efficiency rate ÷ electrical power of using (W) such as the 12V DC input inverter uses the 12V battery, if the battery capacity is 200AH and at this time the inverter is driving 400W power load, the efficiency rate is 90% when the battery is full, according to the formula above, the battery use time =200(AH)÷(400÷12x110%) = 5.4 (Hour). This means the battery can be used for 5.4 hours.

Notice: The nominal battery capacity is the discharge capacity in 20 hours discharge rate ,under the condition when the discharge current exceeds this value, the discharge capacity will be reduced, the corresponding discharge time will be shortened than the calculation value, this part of the specification can refer to battery manufacturer,and whether the battery fully charged will also affect the results.

CONNECTION

1. Grounding
   The power inverter has a terminal on the back panel marked "Grounding" or " ". This is used to connect the chassis of the power inverter to the ground.
   The ground terminal has already connected to the ground wire of AC output receptacle through the internal connecting wire. The ground terminal must be connected to the ground wire, which will vary depending on where the power inverter is installed. In a vehicle, connect the ground terminal to the chassis of the vehicle. On the ship, connect the ground terminal to the ship grounding system; In a fixed position, connect the ground terminal to the earth.
   Warnings
   • To ensure the firmness of the connection. The ground wire must be 14AWG （ 2.08mm2 ） or even larger.
   • Do not operate the power inverter without connecting to ground. Electric shock hazard may result. 
2. Connect to the battery
   1. Please do all the safety precautions before connection, then check whether the battery voltage is in accordance with the input voltage of the inverter. Only the voltage of battery according with the requirements can be allowed to connect with the inverter.
   2. The connecting wire must be big enough to bear current, or else the inverter can not support big load because of voltage reduce caused by the small cross-sectional wire. Depending on the below table, please select the input DC wire or larger one.

Notice

1. The above table is only for your reference. In practice, the thick wire can be replaced by two thin parallel wires if only the total section acreage of the wire meets the requirements. 
2. In high current, the input DC wire may produce voltage drop, therefore,the operating voltage should be subject to the value on the terminals. If the voltage drop is too large, it can increase the acreage of the section or reduce the length of the lead. The recommended length of lead is less than 1m.

Operational principle

• The inverter converts DC to AC, conversion process is divided into two steps, the first step is to convert low voltage DC to high voltage DC , the second step is using the full bridge converter tech to convert high voltage direct current into alternating current.
• The conversion circuit adopts advanced power device and high frequency power conversion technology. Compared with the traditional inverter using the power frequency transformer, it has the characteristics of small size, light weight and high conversion efficiency etc.

OUTPUT VOLTAGE AND WAVEFORM

The output voltage waveform of the inverter is called "quasi sine wave" or "modified sine wave", it is a step waveform similar like household alternating current , this type of waveform is applicable to most of the load, including linear or switching power supply, transformer, electric motor etc. Since the output voltage waveform of the inverter is different from AC, RMS with general analog or digital multimeter can not accurately measure the output of the inverter, please use the true RMS digital multimeter to measure, such as FLUKE 177/179 multimeter.

About soft start technology

 This inverter has advanced soft start function. The output voltage rises up from low to normal when the inverter is turned on. 

1. This can reduce high startup currents, which can make startup easier for large inductive loads. 
2. As for the large inductive loads, such as electric tools and capacitive loads, We suggest turning on the switch of the appliance firstly and thenthe inverter's. The soft start .May be enough to power the high staring.
