Our first decision was to use the on-board 24 volt system in the “house”. A second independent alternator was fitted for charging two Lifeline deep cycle “house” batteries exclusively. Joined in series, these 12 volt batteries will produce 24 volts with a total 100 amp capacity for the “house”. Mounted on a sliding tray they’re accessible from the side door for servicing.
The first junction in our electrical layout is a bus bar which transmits power from the the batteries to the fixtures.
Our needs are basic: lights and ventilation fans. Some of our “appliances” don’t have switches and require a distribution panel. The first line from the bus bar goes to this 6-gang distribution panel that has in-line fuses.
From this panel, using the rocker switches we’ll control two muffin fans and the pre-existing ceiling light/ventilation fan. Bonus – the panel also includes two USB ports, a 12V DC socket and a voltage readout.
Other “appliances” including two LED cabin tube lights, a gimballed cabin fan and a LED goose-neck reading light have built-in switches. From the bus bar, the second line goes to a fuse block. From the fuse block, lines go to each of these “appliances”.
Charging 110V appliances such as a camera, laptop and flashlight batteries demanded our electrical layout include a pure sine wave inverter.
The inverter, directly connected to the house batteries is also grounded to the vehicle chassis. This 350 watt inverter won’t handle the load a toaster requires but it’s more than adequately sized to meet our needs.
For safety and to keep wiring tidy, surface conduits are used throughout the “house”.
With a great deal of help from our friend Steve, the electrician we can see light at the end of the tunnel.

Are you planning any solar panels? We put two 160 Watt panels on our Mog/Camper. I sleep with a CPAP which draws our single 12V battery well down over night, but by noon we are fully recharged by the solar panels. One of our better ideas, for our particular use.
