Solar controller wiring

[WallaceandGromit]

swapping the PWM controller for an MPPT and am a bit stumped the wires to what I assume is the battery are very thin and a wire to one of the solar panel connections. I've fitted 100s of solar panels and always avoided factory fitted controllers etc and kept them separate so if there's a problem I knew the connection layout

My god, there's going to be some voltage drop on those - did the battery ever receive any charge?

My thoughts think I'll just the way I've always done it just like to know where the feck they go

Solar looks normal but battery too thin but depending on amount of solar would work if battery was really close I guess.

Had a light bulb moment last night most swift vans come with a 100 watt controller so looking at the wiring I think a PO cut the connector off and wired to their controller
