It is inevitable that photovoltaic inverters will have some minor faults after long-term use. When repairing the inverter, we should pay attention to the following points:
- Power outage: The connection between the inverter and the power grid must be disconnected, and the DC measuring appliance must also be disconnected.
- After powering off, wait five to ten minutes for the internal components to discharge before repairing.
- Maintenance personnel should wear anti-electricity gloves and electrostatic bracelets in accordance with regulations, try to avoid contact with the circuit board during the maintenance process, and pay attention to and comply with the warning signs on the product.
- The radiator of the photovoltaic inverter will still be at a high temperature for a period of time after the power is turned off. Pay attention to the surface temperature before operation to prevent burns. In addition, pay attention to whether there are other safety hazards.
- After the maintenance is completed, make sure that any faults that affect the safety of the photovoltaic inverter have been eliminated and the environment where the inverter is located meets the requirements before starting the photovoltaic inverter.
