We built a foldout PVC frame for this “extra” panel so we can prop it up and plug it in when needed. Step 1: Calculate the amount of electricity you plan on using in Watt-hours (Wh). And those are in series with the first battery. I’m a little confused on which appliance has priority for that slot, or is it acceptable to leave it empty – if you’d even want to? I’m concerned about the solar_factor variable you use to compute the required power output from the solar panels. Go bigger if you can with this, unless you don’t have enough roof space or if you’re on a significant budget. Solar Panels (DC) Solar panels are a great supplemental and sometimes primary power source for many RVs. Ok, next up is the inverter. If you have to run these, this inverter number is our general recommended max size based on your batteries. Yet easy to use, but many left us with a single 50Ah AGM just to run the units.
