Battery Power is Operational

Yesterday I spent the day wiring up a battery system for the camper so we can have lights, fans, stereo, furnace fan and running water pump when off the grid. This will also give us the flushing toilet and working shower with power for the water pump now.

After hours of research and discovery I ended up going with 2 Trojan T-105 6volt batteries wired in a configuration to output 12volts, which the inverter then converts to power usable by all the stuff. The battery box on the camper is so small there is only room for 1 battery, and that one would have to be about a 100amp/hour 12volt unit which would not be anywhere near enough to run the furnace and pumps for more than part of a day. So, I elected to go with a truck bed mounted battery set up (photos below) which allowed me to go with bigger batteries, with more juice for longer stays.

I read and reread this website a dozen times, it is a one stop education on RV electrics. The 12 Volt Side of Life its a must see. Thanks to Mark Nemeth for the time and effort put into it.

I am now ready to move on to the next step of this adventure.

Actually putting water in the fresh water tank, leak checking the piping and holding tanks and figuring out how that whole system works. Without the battery power, there was no way to pump the water from the fresh water tank, to the holding tanks to see if everything would be ok before I actually put “wasteful” like things in the system.
