I have 2x80w solar panels on my MoHo,they are linked to 2x85amp LB's through a 20A C2430 Solar Controller using 6mm cable.
I fitted it all about 18 months ago and all has been fine with periods of up to 6 weeks off grid in Portugal last year.
Went to storage last week and LB's down to 11.5v and contoller showing low battery and no charge(low winter sunshine). Took her out for the day,,,,,70 odd miles and batteries back to normal. Next day down to 12 .3 v and contoller still showing no charge,checked all wires and connections,all good.
Multimeter reading showing between 1.5 and 2v from panels but no charge to batteries.
Do l suspect my controller or am l expecting too much from solar in low January sunshine.
Any help/advice or even the usual derogatory comments appreciated
Cheers Bob. :thumb:
