When we purchased our RV, we knew we wanted to be as self reliant as possible. This was part of attaining the simple life we wanted! My husband researched for hours upon hours how solar power works in an RV application and became fascinated with the idea of installing them on our RV. We did not just want to go with the cheapest single panel setup. We wanted to be able to store enough power to not have to plug in to an outlet. With a family of 8, we knew we would be consuming a lot of power, therefore we researched even further to get a plan together on how to do it. There are 4 main components to having an off grid system. The panels, the batteries, the inverter and the charge controller. We were able to find a great deal on new panels, still in the box. A local man had purchased them a few years prior and was not able to use them. Ricky installed (12) 100 watt mono-crystalline Sunwize panels to the roof of the RV using a custom framework out of aluminum poles. This framework will allow us to tilt the panels for maximum exposure to the sun at each of our destinations. Next we purchased 8 Trojan T-105RE batteries for the battery bank. For the inverter we purchased the Magnum ms-pae4024 4000 watt Pure Sine Wave inverter. Then we bought the Magnum PT-100 100 amp charger controller. Ricky has been working on this further still researching the absolute best way to wire the system. Our goal is to have everything completed in 2 weeks so we can begin this crazy adventure! We will keep you updated on the progress. Please feel free to ask any questions or give feedback!
