OK Folks, here is my design for the electrical system within the van.
I have taken this as a pure 12v system, running a split charge between the alternator and the roof mounted solar. Up top I am fitting 2no 120W panels in parallel, giving 240W of solar up top, running through a Renogy 30A DC-DC MPPT unit. This is used to charge a pair of 130mAh Deep Cycle leisure batteries with full isolation of the system.
Off this, I am running 2 dedicated busbars for positive and negative, taking this to a 12 way fuse board for circuit isolation.
Plan is to run 4no. 12V LED downlighters, a mobile WiFi router, a 24″ Samsung flat panel TV, a 12V fridge, pump for running water, a USB quick charge dock and a Piezo ignitor for the gas ring. This should give us enough for hunkering down in bad weather, running water for cleaning and coffee, lighting, charging for phones/tablets etc and a means to keep things like milk cool when out and about.
Can anyone see any obvious errors? Anything coloured in green I have already bought and have here, in case you were wondering
