Solar system tripping out mains.

[PC Electrics]

And I'm pretty sure a Hager RCBO will fit into an M2 board ok.

Should mix MCBs of a different make into a consumer unit!

weres the CPC? then i wonder whats down for the R1+R2 test? its difficult to see.

I'm out of my depth a little here.... would any photos help?

A photo of the wires from the CU heading to the loft would be useful/

I think I spy a green and yellow cable running up the side of the consumer unit next to the SWA(?) cable, which I'm thinking might be coming from the AC isolator, which would slightly improve the situation compared to my first thoughts, but using the dbl insulated single core PV cable in that way seems dodgy as to me due to the lack of cpc as you say.

well theres always more than one way to skin a cat as they say, but it just doesnt look good and most electricians wouldnt do it like that i guess.

The green cable runs from the isolator to the CU, so I assume that the cable from the inverter in the loft to the isolation switch is twin & earth.

Can you please clarify? The cables from the CU run to the meter, then the isolator, then to the loft. What would help you see?

What area do you live, if someone on here is local they might pop around and advise you.

I hope this helps.
