How to Diagnose Solar Faults (with live examples) 🤔

[@eddtheduck]

The Fronius IG TL solar inverter has a built-in DC disconnector and a DC supply isolation method that is usually a rotary switch

Think you can see it at the bottom of the inverter?

You stated that the rcd should be a 30ma, you really need to check with the manufacturer as many are infact 100ma and sometimes 300ma. I know this as I have requested this from many manufacturers.

Be careful just Having DC voltage isn't the be all and end all you need to check the sort circuit current
