6 FAQs about [The photovoltaic inverter displays abnormal parameters]

How to maintain a faulty solar inverter display?

To maintain a faulty solar inverter display, you can proceed with the following steps: Begin with turning off the input PV switch on the photovoltaic inverter side. Next, disconnect the PV input DC switch and finally, switch off the battery switch.

What happens if a PV inverter fails?

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. Turn off the AC output switch, then the DC input switch.

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.

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.

What are solar inverter error codes?

Solar inverter error codes notify you of a situation threatening the normal operation of your solar power system. 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.

Why is my solar inverter NOT working?

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. Wait until the level of solar irradiation has increased. If necessary, remove snow or dirt from the PV modules.
