6 FAQs about [Photovoltaic inverter starts late]

What if my solar inverter is not working?

There are a few ways that we can help with this: Solar Inverter Replacement * DC-INTF - Battery overcurrent - If after the system has been safely shutdown and restarted this condition persists the inverter has a fatal error and should be replaced.

Why is my solar inverter not measuring a grid voltage?

* NO-GRID - No grid voltage - The solar inverter is not measuring a grid (mains) voltage suggesting that mains power to the unit has been disconnected. If this fault persists and mains power is available to other local circuits then check that all isolators, MCBs and RCDs on the AC side of the solar PV system are 'On'.

How do I restart a solar inverter?

When all of the lights on the solar inverter have gone out, reintroduce the AC/mains power supply by turning the AC isolator 'on'. Introduce the DC supply by turning all DC isolators 'on'. This will restart the solar inverter, on the display it might show you progress during it's startup procedure.

Why is my Solis solar inverter NOT working?

Solis solar inverters are powered by the solar panels (the DC supply) and will startup at sunrise each day and shutdown at night. If you find the solar inverter with no lights or display working during the day, there is either a problem with the solar panels or with the solar inverter.

How do I know if my solar inverter is working properly?

Switch the AC isolator 'off', if the solar inverter is running correctly you will hear a clunk inside the machine and after a while a 'no-grid', 'missing grid' warning or similar on the LCD display. Near to and or built into the solar inverter will be a method of isolating the solar (DC) supply from the solar inverter.

How do I start a solar inverter?

Introduce the DC supply by turning all DC isolators 'on'. This will restart the solar inverter, on the display it might show you progress during it's startup procedure. During startup is when the solar inverter carries out all of the tests needed before being able to connect the solar supply to the electrical system.
