Inverter as an important power equipment, in the event of failure, we must promptly and quickly determine the location of the fault and find a solution. We will list several common faults and solutions.

1, inverter without DC input
The reason of such failure often happens is the battery is not connected properly, the inverter polarity of battery and must be correct, the cathode is connected with the anode, cathode is connected to the anode, properly connected switch, can solve the fault.

2, inverter input and output fuse
Such failures can generally be seen, as long as the replacement of the fuse can be.

3, the battery voltage is higher than the rated DC input voltage 20%
The inverter has a working voltage range, generally between the rated DC voltage +-10%, if higher than this, the need to replace the battery or replace the inverter, to prevent damage to the machine.

4, the battery voltage is lower than the rated DC input voltage of 15%
This kind of problem is mainly due to the battery power shortage, only need to charge the battery can be.

5, the load power is too large
This type of problem is mainly caused by the lack of load power calculation, the need to increase the power of the inverter or reduce the load power can be.
