If the inverter's display doesn't show any lights or activity, the most common problem is that there is no DC voltage to the inverter. All of the Ginlong inverter's internal electronics are powered by the DC. If there is no DC voltage the inverter will not power on.

What are the most common problems with solar inverters?

A possibly obvious, yet very common problem with inverters is that they have been installed incorrectly. This can range from physically misconnecting them to incorrect programming of the inverters. The construction of a solar PV system is usually carried out by an EPC party which in turn appoints installers.

Why is my PV system not working?

These two conditions which may require troubleshooting are: Zero output is a common problem and in nine out of ten cases, it is due to a faulty inverter or charge controller. It’s also possible that one solar panel in your pv array failed. As the pv modules are connected in series, one failing pv module will shut down the entire system.

What happens if a PV inverter fails?

If this is not organised properly, all PV modules connected to the inverter will be unable to deliver power until the fault has been discovered and an engineer has rectified the fault. This is a problem that particularly occurs in areas where the grid connection is not always stable.

What causes a solar inverter to fail?

As highlighted in the photo, DC isolators mounted next to solar inverters are another common cause of failure, especially if the solar conduit enters the top of the isolator, allowing water to flow directly into the isolator if there is ever a broken seal or crack along the conduit connecting the rooftop solar array to the inverter.
