FAQ
- Can I add a fuse or circuit breaker between the input terminal of the inverter and the battery? If so, what specifications are recommended?
Yes, the following is the calculation of fuse ampere.
Continuous power of the inverter ÷ Lowest input voltage = Fuse ampere, e.g.
1000W 12V version: recommend a 100Amp fuse (1000W÷10VDC=100Amp)
- Why did sparks appear on the cable and the inverter terminal when connecting the battery to the inverter?
This is normal, and it does not mean the inverter is malfunctioning. The inverter has built-in capacitors, so when the battery cable is connected to the inverter input, a small spark may appear as part of the charging process.
- Why does the inverter's output voltage keep dropping or even shut down automatically when running loads?
First, check whether the fuse or breaker size is correct. Second, make sure the battery cables are thick enough and all supplied cables are used correctly. Third, check whether the battery capacity is too small for the load. Thin cables, long cable runs, or weak battery systems can all cause voltage drop.
- Why can't the inverter be turned on?
Please fully charge the battery before installing the inverter. When battery power is too low, the inverter may enter low-voltage protection or fail to start.
- Why can't my inverter run the refrigerator or motor load?
Some inductive loads may need much higher startup surge than their running power. Before connecting, make sure the appliance startup requirement stays within the inverter's peak surge power. If the load is difficult to start or highly sensitive, a pure sine wave inverter may be the better choice.
