Re: Is there a schematic for the Immersun PV diverter? I need to replace 2 capacitors

🤣🤣 I don't know the history but it sounds like I missed out on some drama haha The wayback machine is brilliant, it basically does a save of pretty much every website at certain dates so if anything gets deleted you can always go there in the hope it's in the save. I just completed a big coding job,...

Re: Is there a schematic for the Immersun PV diverter? I need to replace 2 capacitors

Don't know how I missed those, I saw them too but thought they were part of the 5v circuit that runs underneath them. They're all testing fine thankfully I've seen a few posts about those varistors going bang, seems like the most common problem with these. Everything is testing good on this board no...

Re: Is there a schematic for the Immersun PV diverter? I need to replace 2 capacitors

Thanks for your reply Marcus, I did check Q7 and Q8 they are both reading the same as the Q12, Q11 etc. They're not shorted and there's no psyical damage. I think the traces blew out before it caused any other damage from the look of it. The capacitors didnt blow, they were singed from the heat of t...

Re: Is there a schematic for the Immersun PV diverter? I need to replace 2 capacitors

Thanks for the welcome, I saw that video, my problem is unfortunately on the opposite end up of the board. The max voltage for the 10uf smd multilayer capacitors seems to be 100v anyway though so it can't possibly need a 1kv I need 2 different caps, on my testers they're coming up as 50nf and 11.x u...

Is there a schematic for the Immersun PV diverter? I need to replace 2 capacitors

Hi guys, I need to replace 2 capacitors from my immersun solar PV, an IGBT has blown and took 2 of the caps with it. I'm just not sure which voltage rating to get as they're on the emitter side and it's max output is 600v. Struggling to get hold of 1kv capacitors so I'm wondering if I can get away w...
