After weighing all of our options, we have decided to go with an all electric house system and power our #BusLife by the sun. We currently have six 235W Solar Panels with a plan to expand and have a total of over 3000W of solar on our roof. Capturing the power from the sun is one thing but the key to going solar is all about storing that power.
After years of research we knew LiFePO4 (Lithium Iron Phosphate) batteries were the way to go to power our future home. In our search we kept returning to Battle Born Batteries as our top choice to install in our system because of their reputation and reliability.
The most important features for us for choosing Battle Born Batteries were the built in battery management systems and the support from the Battle Born team as we approached learning about building an electrical system.
Battle Born suggested we go with the 3x BBGC3 also known as the Gamechanger 3.0 which is 12V 270 Ah Deep Cycle Lithium Ion Battery. Having 3 of these for our bus is the equivalent of having a little over eight 100Ah hour batteries. What we like about he BBGC3s already is they have a small footprint and only weigh 80 lbs each.
In order to be sure we would have enough solar and power for all our needs, we first collected data on the power draws for the appliances and electronics we will have in our bus.
We used Dons Dad's multi meter to measure the power usage for the things we already had and estimated the usage for the appliances we still needed to purchase. We created a detailed spreadsheet, shared it with Battle Born and they came up with a system recommendation so we can stay off grid and know we won’t run out of power.
We’ll share more on our full electric system and all the components we’ll be using when we get to the electric bay install, but first on the agenda was getting our solar panels secured to our roof rails.
To mount the solar to the roof rails, we used four z bracket on each solar panel and then clamp brackets between the panels closest together. We were given the tip to place some wood under the lip of the panel frame while we drilled holes for securing the z brackets to make sure we didn’t drill into the solar panel and crack it, which worked great.
We used Loctite Threadlocker Red 271 to adhere the bolts and nuts we used for our brackets and ran all our 12AWG PV Solar Cable inside the unistrut channel connecting to PV Y Branch Connectors .
We pulled out our old bus antenna (which we are not using) to position a Weatherproof Solar Cable Entry over and utilize the whole in the roof that was already there.
We used some conduit piping to thread our wiring through our ceiling and wool insulation and sikaflex 221 to seal the entryway.
We prepare one of our luggage bays to house our electric system.
