What is inverter?

Inverter is an electronic equipment that turn 12v/24v/48v DC into 110v/220v/240v AC.


How many kind of output wave form for inverter ?

Two kinds. Pure sine wave and modified sine wave. Pure sine wave inverter could provide high quality AC and carry various loads, while it requires high tech and high cost. Modified sine wave inverter load poorly not carrying inductive load, but the price is moderate.


How do we equip an appropriate inverter battery ?

Take a battery with 12V/50AH as an example. Power equal current plus voltage then we know the power of battery is 600W. 12V*50A=600W. 

So we can choose a 600W power inverter according this theoretical value. 


Installation Guide

1. Install the unit according to wiring diagram, and improper wiring may lead to permanent damage to the unit;

2. Normal AC mains supply, the inverter allows the battery pack charging, trickle charge to maintain battery performance. 

Sudden interruption of the mains AC, then the inverter converts DC battery powered to ensure that lighting and security;

3. Inverter with multiple protection functions: charge protection, discharge protection, short circuit protection;

4. To ensure maximum protection of the built in battery, please fully charge the unit for 24hours after first installation. 

To extend battery life please make sure charge the battery at least one time every three months;

5. Dont install top of the high temperature objects. Please ensure that the operating ambient temperature is below 50C, 

and maximum case temperature(tc) not exceeding 70C; 

6. Do not operate this unit beyond the operating supply range;

7. In normal use, the battery can be done 700 charge/discharge cycles
