What Should I Pay Attention To When Repairing Photovoltaic Inverters?

It is inevitable that some small faults will occur in the photovoltaic inverter after long-term use. When repairing the inverter, we should pay attention to the following points:

1. Power failure: The connection between the inverter and the grid should be disconnected, and the DC measuring device should also be disconnected.

2. After the power is off, wait five to ten minutes for the internal components to discharge before repairing.

3. Maintenance personnel should wear anti-electric gloves and electrostatic wristbands as required, try to avoid contact with the circuit board during maintenance, and pay attention to and follow the warning signs on the product.

4. The radiator of the photovoltaic inverter is still in a high-temperature state for a period of time after the power is turned off. Pay attention to the surface temperature before the operation to prevent burns. In addition, pay attention to whether there are other security risks.

5. After the maintenance, ensure that any faults affecting the safety of the PV inverter have been eliminated and the environment where the inverter is located meets the requirements before starting the PV inverter.

Photovoltaic inverters are power products, and safety comes first during maintenance.
