Maintenance Work for Winter Solar Energy Inverters

Understanding winter maintenance of solar energy inverters

The basic structure of the inverter device includes not only the inverter circuit and control circuit, but also protection circuit, output circuit, input circuit, etc. Nowadays, more and more families are using solar inverters to generate electricity. Using photovoltaic power generation is not only more environmentally friendly, but can also enjoy national welfare policies. Moreover, excess electricity can be sold to the grid institution to make money. It is the multiple benefits that make more and more people use solar inverters. Today, we will talk about maintenance work of solar power inverters in winter.

What are the maintenance works for solar energy inverters in winter?

First, for solar inverters, maintenance work must be done when winter comes. First of all, check the line of the photovoltaic array. Since many solar inverters are on the roof, the connection bolts and wires must be checked, and each connection bolt and wire should be tightened. Then check output and adjust the tilt angle.

In addition to the photovoltaic array mentioned above, the tracker should also be valued. For example, the connection bolts on the tracker should also be tightened, and check whether the shock absorption function is normal. If there is a problem, the shock absorption needs to be repaired. In addition, the wiring connection must be confirmed.

Third, the charging controller is the focus of maintenance. Check whether the rectifier voltage is normal through the voltage meter reading. Also, check whether the temperature compensation function of the charging controller is normal or not. The temperature compensation function of the charging controller in many devices are automatically adjusted and do not require manual settings.

Fourth, battery inspection mainly reflects on checking whether the voltage of the battery is normal. In particular, failed batteries must be replaced, and check whether the battery can still be charged evenly.

Fifth, finally, check the installation settings of the solar electric inverter, including whether the wiring connection and each component are working properly. If it is an inverter with charging function, set the charging voltage to about 14.5 volts with reference to the instructions.

The aforementioned points are the key maintenance work that needs to be done before winter comes. Since specific photovoltaic power generation equipment may vary, it is necessary to refer to the maintenance manual of your own equipment.
