6 FAQs about [Common alarm information of photovoltaic inverter]

How to check if a solar inverter is faulty?

The solar inverter has a detection precision of ±1 PV module. Set the DC switch to OFF and check whether the connector or DC cable between the possible faulty PV modules are damaged. If yes, replace the damaged connector or DC cable, set the DC switch to ON, and view the alarm information.

What happens if a solar PV system goes wrong?

Many different things can go wrong and disrupt electricity generation from a solar PV system. The inverter will detect it and generate corresponding error codes to notify you. You should be interested in inverter codes because their performance and lifespan are intricately linked to inverter error codes and taking appropriate actions.

What are solar inverter error codes?

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.

How do I check if my solar inverter is low insulation resistance?

If the Low Insulation Resistance alarm is not reported one minute after the DC is supplied, choose Device Commissioning > Maintenance > Inverter ON/OFF on the app and send a shutdown command. Set the DC switch to OFF and go to Step 2 to connect another PV string to the solar inverter for a check.

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.
