How does the inverter manufacturer check the inverter's fault maintenance?

In order to ensure the reliable operation of the inverter, it must be operated in accordance with the operating procedures of the inverter.

In order to ensure the reliable operation of the inverter, it must be operated in accordance with the operating procedures of the inverter. When the power is turned on, first apply the 110V control power and then 600V for the large power; when the power is off, first cut off the 600V to obtain the large power, and then the 110 V control power, that is, follow the weak current first, then the strong current, light load first, then The principle of operation is overloaded. In order to ensure the safety of maintenance personnel and equipment, the inverter must be inspected five minutes after the power is cut off. The following is a simple method to deal with the inverter power failure given by Baoweite, I hope it will be helpful to you! !

Failure phenomenon

Approach

The output voltage is wrong

Adjust the floating charge/equal charge piezoelectric potentiometer to make the output voltage value meet the requirements

Fault indication warning light is on

Check the condition of the parallel battery, whether there is any over-discharge, damage, short circuit, output over-voltage, output over-current, etc.

The output has indication but the load has no output

Check if the output line is open

Unstable output

1. Check whether the output is overloaded

2. Check whether the input voltage is lower than the requirement. If there is no such situation, send it to the manufacturer for repair

no output

1. Check if the output line is open, if it is open, reconnect it

2. Check whether the input fuse is blown, if it is broken, replace the fuse

3. Check whether the input power cord is open, if it is open, replace it with a new one

If the above treatment does not solve the problem, send it to the inverter manufacturer for repair
