The maintenance of solar inverter

1. Before any maintenance work, the electrical connection between the inverter and the power grid should be disconnected first, and then the DC side electrical connection should be disconnected.

2. Wait for at least 5 minutes until the discharge of internal components is completed.

3. Any faults affecting the safety performance of the inverter must be eliminated immediately before the inverter reopened.

4. Avoid unnecessary circuit board contact

5. Obey the electrostatic protection code and wear anti-electrostatic bracelets.

6. Pay attention to and abide by the warning signs on the products.

7. Preliminary check whether the equipment is damaged or in dangerous condition before operation.

8. Pay attention to the hot surface of the inverter. For example, the radiator of power semiconductor still keeps a high temperature for a period of time after the inverter is powered off.

Finally, after the machine is repaired, it is necessary to ensure that any faults affecting the safety performance of the inverter have been solved before the inverter turned on again.
