6 FAQs about [The inverter of photovoltaic power generation is black screen]

How do I know if my inverter is producing power?

For more information regarding your system’s production and communication, please follow the steps below. Please note: The system doesn't produce at night time. Look for the green LED: when it is on, the system is producing power, if it is flashing, this means the inverter has AC power and is in Standby mode.

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 know if my inverter is working at night?

Please note: The system doesn't produce at night time. Look for the green LED: when it is on, the system is producing power, if it is flashing, this means the inverter has AC power and is in Standby mode. Press and quickly release the green button to activate the LCD screen, repeat until the screen appears.

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.

What happens if a grid voltage disturbance causes an inverter error?

But if grid voltage disturbances cause the error, the inverter will automatically rectify it when grid conditions stabilise. There are communication issues between the control devices inside the inverter. Switch off the inverter and restart it. If the problem persists, contact customer service.
