The power of the inverter must be above the rated power of the operating appliances: Considering the high start-up current of some appliances, inverters with high output power should be chosen.
Voltage of inverter and battery must be matched. For example, if the DC power supply (such as 12V or 24V ) of inverter is indicated, you should access the battery with consistent voltage. Voltage of battery should also be 12V once voltage of your inverter is DC12V, otherwise may resulting the inverter’s dysfunction.
How to use the charging function: Connect it to the city grid at the AC-inputting point. Connect the battery to the inverter as required: Positive electrode to positive electrode (red to red ), negative electrode to negative electrode ( black to black ). Turn off the corresponding switch and then the power inverter with battery charger will charge the battery automatically.
When no city grid is connected to the inverter, connect the battery to the inverter as required. Corresponding switch on panel should also be turned off and inverter output AC provided to the load of appliances.
