Fitted a replacement like for like Solar panel on the van , on the previous panel to avoid the hell of adhesive removal off the roof. Will see how it goes staying put . Then wire it up tomorrow via mc4 connectors this time and new cable with split mc4 so I can plug in an additional 100w Solar panel if needed to boost things up a bit in hotter weather whilst out n about.
Agreed it’s been biblically bad weather here today .might need to double check tomorrow with better daylight.
as its getting dark now.
drop a link to the panel so we can check the website.
what wattage etc?
I did but took it off after the first fix to concentrate on the primary set up first.Did you use the split mc4 connectors? Got a pic of that connection?
Ah ok, that's good. But also not good as it might have been a strange set up with the split mc4 connectors.I did but took it off after the first fix to concentrate on the primary set up first.
Yeah it was the same as previous mainly so I didn’t have to rip off the old panel and used it as a footprint.only 80w so you wont get much from it . .
............
that test before tests this :
- Short circuit current: 4.20A
but with no sun you wont get much . . ---
but i would have expected 0.5A / 1.0A - something

Yes definitely. If you can, plug it in now - you might only see 1v but that would be enough to confirm the MPPT is ok. Obviously the battery won't charge at that.Yeah it was the same as previous mainly so I didn’t have to rip off the old panel and used it as a footprint.
Actually just thought I have a 100w portable panel with mc4 I might test that on the system tomorrow too?
