Hi AsdaPricey, I'm glad the van colours remind you of positive experiences. I was in Europe for about a year many years ago travelling in an ex-Post high roof Mercedes van. One of a series of motorhomes and campervans.
The solar controllers commonly used here are the Victron brand and that's the brand I've gone for. The residential solar panels I got cheap as they were left over from a job. I've got 2 x 450watt and they do a wonderful job.
Lots of sun here negating the need for a B2B set up. The inverter came with the van .. a generic 2500 watt that happily runs a microwave and induction cooker. The 300Ah battery is a local (Kings) branded Chinese one.
This is a photo of my MPPT controller, digital clock and switch/fuse panel with voltage gauge. The small panel in the middle is a Victron Solar MPPT control display that provides all sorts of information ... present time current in and out, cumulative in and out etc.
It's a bridge too far to heat enough water for a shower with solar and showers use a lot of water.
We boil a kettle, pour the water in a bucket and have a cat bath with a cloth. That seems to be enough so that we don't stink each other out.
All the best with your conversion
Tom
Here's a photo of the 4x4 Canter. (I liked to hide in the bush hence the camo paint job!)
