e.g 3000W 12VDC version
1). Pls check If there is a fuse or breaker installed in your systemGenerally,we recommend that a 300Amp fuse be installed between the inverter and the battery.
2). Pls check if use standard cables all . If 4 cables, please use them all, or the output will only be about a half. If you use your own cable, please make sure that the cable specification is larger than AWG 4, and if the length exceeds 24 inch, please thicken the cable .
Note that there is a voltage drop between the battery and the inverter. The thinner and longer the cable, the greater the voltage drop
Pls check if the battery capacity is too small .We recommend connecting to a battery system ≥ 300AH for a 3000-watt 12vDC inverter. When the DC LED reading drops while the load is running, it is likely that your battery capacity is too small to supply power to the load. Please try to add other batteries to your previous battery system.
