1. The power of the inverter must be greater than the rated power of the electrical appliances used. Considering that some electrical appliances start the current is larger, should choose the inverter with larger output power.
2. When the inverter is working, the DC voltage and frequency voltage of the inverter should match the battery on the street. The inverter has an indication of a DC power supply (e.g. 12V, 24V, etc.), so the battery voltage you are connected to must be the same.
The inverter voltage is DC12V. Then your battery voltage must also correspond to 12V, otherwise the inverter will not work or damage.
3. The positive and negative electrodes must be connected to the positive (red) of the inverter and the negative (black) of the battery.
4. When charging (some users may not need this function), press the power supply at the AC input end and connect the battery and inverter correctly as required. Positive pole connects positive pole (red to red) and negative pole connects negative pole (black to black). At the same time, the machine has the function of automatic bypass, automatic bypass output to the load after the mains power input, automatic switch to the inverter output after the mains power cut, continuous power supply to the load.
5. When the inverter is in use without mains power input, connect the battery and inverter correctly according to the requirements, close the corresponding switch on the panel, and the inverter outputs AC power to the electrical load.
