As autumn and winter approaches, lowtemperatures are approaching, and there are more and more things to payattention to when using photovoltaic system. In addition to choosing morestable photovoltaic products, regular maintenance is also necessary.

First, check the circuit of the photovoltaic array, check the connecting bolts and wires, tighten each connecting bolt and wire, and then check the output and adjust the tilt angle.

Second, tighten the connecting bolts on the tracker to check whether there is a problem with the damping function. 

Third, the charge controller is the focus of maintenance. Check whether the rectifier voltage is normal through the reading of voltmeter, and whether the temperature compensation function of the charge controller is normal.

Fourth, check whether the voltage of the battery is normal, Ifit is abnormal, the faulty battery must be replaced, and check whether the battery can still be charged evenly.

Fifth, check the installation and setting of the inverter, including the circuit connection and whether each component operates normally.

By achieving the above points, the servicelife of the photovoltaic products can be extended, ensuring that you are saferand more at ease when using the photovoltaic system.
