The system I will build is very simple yet very effective.
It will provide 24/7 power for all lights inside and out(LED of course), USB power plugs, 12Volt Fridge, water pump, 12v - 240v inverter and any other 12v power required.
The main system consists of:
2 x 200watt Mono-crystalline Solar Panels
2 x 100Ah Gell Cell Deep Cycle Batteries (Second hand)
1 30A Solar controller
1 12V Fuse Box
Various connectors, fuses etc
This system really doesn't need to be connected to the vehicle's alternator for extra charge, the solar panels do very well indeed. This makes it a lot cheaper and simpler than other system I see around.
In my opinion the only situation where you might need something more is where you plan to run 240v devices daily such as a washing machine or microwave, that would drain the batteries running through an inverter. Of course you could build a bigger system with bigger batteries and more of them, but that will add significant weight to the Van. The 200Ah batteries that I can source are 85kg each! In any case I can only put together what works for me, and that's what these posts are all about.
I am doing an almost complete rennovation on the van for my Uncle, this is what it looked like to start with...
