6 FAQs about [Photovoltaic inverter prompt alarm]

What is PV abnormal alarm (548-551)?

It is not a statement or advice on any of the Electrical or Solar Industry standards or guidelines. Please observe all OH&S regulations when working on Sungrow equipment. PV Abnormal Alarm (548-551) is a warning indicating that the inverter is detecting an unexpected amount of current through the strings or the MPPT.

What happens if a PV inverter is reversed?

Correct PV string connection if reversely connected. Increase the number of PV modules connected in series to the inverter. The protection for the DC circuit is triggered. This occurs if the inverter input accidentally disconnects, the three phases of the grid become unbalanced or if there’s a fault on a circuit in the inverter.

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 causes a solar inverter to fail?

Inverter failure can be caused by problems with the inverter itself (like worn out capacitors), problems with some other parts of the solar PV system (like the panels), and even by problems with elements outside the system (like grid voltage disturbances). An inverter failure is when the inverter develops faults that cause improper functioning.

How do I Turn Off PV alarm on my sg10ktl-mt?

Figure 6 Bluetooth Login Once logged in, click on “More” on the bottom right, go into “Advanced Settings”, select “String Detection” and simply turn off. A special case for PV abnormal alarm to occur is when it is cause due to both reasons mentioned above. This is mostly common for SG10KTL-MT.

Why is my PV system not feeding into my inverter?

If this message is repeated frequently, contact the SMA Service Line. The inverter has detected a ground fault in the PV array. As long as the fault exists, the inverter will not feed in. Check the PV system for ground faults ( > Checking the PV System for Ground Faults). The PV array voltage is too low.
