Hi, I have a camper van with no solar currently, but I'm looking to change that!!
I was looking at mounting 2 x Mono 140w blue solar panels on the roof bars it possible (permanent bars that were installed befor we bought it and we dont use!!). So i know I need 2 panels, cable and gland box of some sort to get the cables into the van, but from there to our batteries, what do i need? we have 2 separate batteries currently, with a rotary switch to change from one to the other, so the batteries are never both connected at the same time, we just use one, and when it gets down to 11.9v we manually change the system over to the second battery... There is an old system in the van that links the van power (alternator) and the plug in 230v to charge the leisure batterie, but i dont want to add any more load to this device, just run the solar direct to batteries effectivily...
