Hello,

Bit of a solar newbie here. Got an Aurora Power One PVI 3.0 Inverter I think is dead but would value other opinions...

I've inherited a Solar PV system when I bought the house a few years ago, and in the last couple of weeks the generation meter has stopped working (completely blank) so I started investigating. The inverter seems to be completely dead. From a bit of searching here and elsewhere I can see these seem to suffer from a common fault https://www.electriciansforums.co.uk/threads/power-one-dreaded-e031.109799/ but in my case it's totally dead. no lights, no nothing on the inverter.

Took a multimeter to the 2 strings, both are showing about 185V DC and it's a sunny day.

Am I missing anything before I start looking into replacement inverters?

And is it common that a dead inverter would kill the generation meter? Doesn't AC support that?

Many thanks for any views....  Smiley

Hi
Might be worth checking the MCB or RCD or RCBO on the supply for the inverter on the AC side. Either in your consumer unit or mounted separately.
If the MCB,RCD,RCBO is open the TG meter will go blank. No AC from the Mains and no AC from the Inverter.

Welcome to the forum. There are specialists who repair inverters, eg C Gascoigne Ltd in Loughborough (no connection).

Thanks for all replies.

Iain/Tinbum - You're right of course, I hadn't spotted the MCB had tripped. So that's got the generation meter back and working. Thanks.

Solid red light on it now, which is what I'd expect = zero generation.

So now it's just the inverter - reintroducing AC hasn't made any difference to the status there - no lights, nothing. But that's what I'd expect really as from what I've read the Aurora will power up on DC voltage alone - and there's plenty of that today.

Stan - thanks for the insight, I am mulling that one. Called ABB and the inverter is 8 years old and out of warranty....everything else I've read suggests replace rather than fix?
