The solar inverter is not producing 220V AC power. There are three situations that will prevent the inverter from producing:
First; the inverter is burned out, check the internal power board of the inverter. Observe whether there are burn marks and judge whether the inverter is complete from the surface;
Secondly, the inverter's own output is protected when the battery is low voltage, high voltage or overloaded. the inverter will alarm and shut down for added protection. Check whether there is alarm protection before the inverter shuts down the output;
Third; if the battery is normal, the battery is used
Under conditions of 2-3 years, the internal resistance of the battery will be damaged more or less. In many cases, customers report that the inverter cannot be used. In fact, the battery was damaged. by eye if the battery is If there is a bulge or abnormal sound, useUse a voltmeter to actually test the voltage of a single cell of the battery to ensure whether the battery is normal.
