6 FAQs about [How to solve the black screen of photovoltaic inverter]

Why is my solar inverter screen blank?

If the inverter screen is blank, is it dark outside? Most inverters won’t liven up unless your solar panels are generating. If there is enough light outside for the panels to generate and the inverter screen is not showing anything then there’s a good chance there’s no grid supply to the inverter.

How do I know if my solar inverter is working?

Allow a few minutes for the inverter to restart, during which the lights may flash on and off, and various status messages may appear on the display screen. If necessary, you can run a test for the wattage from your solar panels to make sure they are functioning correctly.

How to turn off a solar inverter?

If you wanna turn off the inverter, please turn off the AC breaker first, then turn off the DC switch till the DC current is less then 0.5A, or do it at evening when the sun is set. 4. Use a multi-meter to check the voltages between PV+ and earth, PV- and earth of all the PV strings.

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.

Why is my solar inverter NOT working?

Solar inverters are intricate devices which, like all electrical appliances, can go wrong from time to time. However, sometimes when it appears that the inverter is faulty, the issue is actually caused by another part of your solar panel system. Is the inverter screen blank or are there no lights?

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.
