Maintenance matters and maintenance methods of solar inverters

  The use of solar inverters

1. When connecting and installing the equipment we should strictly abid by the provisions of the solar inverter maintenance and repair manual,  carefully check whether the wire diameter meets the requirements; Whether components and terminals are loose during transportation; if the insulation is good or not; Whether the system grounding meets requirements.

2. The solar inverter usually has overcurrent, overvoltage, circuit break, overheating and other automatic protection functions, there is no need to manually shut down these phenomena; Automatic guard points are usually installed at the factory and do not need to be adjusted.

3. Strictly abide by the provisions of the maintenance instructions of solar inverters. Especially pay attention to whether the input voltage is normal before runtime; pay attention to the correct order of the switch during operation, and whether the instrument and indicator light indications are normal.

4. When the indoor temperature exceeds 30 ° C, thermal management should be implemented to avoid mechanical failure and extend the life of the equipment.

  Solar inverter maintenance

1. Regularly check whether the wiring of each part of the inverter is solid and whether there is a loose phenomenon. Check the fan, power module, input, output terminal and grounding carefully.

2. If the alarm stops, it cannot run immediately. The reasons should be checked before running. The inspection should strictly abide by the procedure stipulated by the inverter repair manual.

3. The operator must pass the training to ensure the cause of the general failure and exclude it, such as the proficient replacement of fuses, components, damage board cards, etc. Those who are not trained cannot work on the device.

4. When the cause of the accident is unknown, the incident should be recorded in detail and inform the inverter manufacturer to communicate and negotiate with the manufacturer to solve the problem.
