  • Inverter/Charger and Solar Charge Controller - Current Concern - Trailer

    I've built a 24 volt battery system in a travel trailer before, but I never got around to installing the solar. So... current concern (pun intended). My inverter/charger is 3000 watts, capable of charging the 24v battery at 120 amps. If I add a solar charge controller that's capable of 50...
  • Solar Charging While Driving?

    Possibly a stupid question, but my wife asked and I couldn't say for certain. We're planning a long cross country trip this summer, I'm planning on 1,365 watts of solar for our travel trailer's roof. Will those panels charge our batteries while we drive? It seems like they obviously would, but...

    Hi y'all! As I catch up on all the latest info (I built my batteries 2 years ago) I see a lot of chatter about active balancers. I already own 2 Overkill 8s BMSs for my 2 24v batteries, so I figured I'd add a NEEY 4th gen 4 amp active balancer to each battery and call it a day. Then I saw the...
  • DC Switch for lights, switch positive or negative leg of circuit?

    This may be a silly question, but I'm new to wiring the DC load side of the house. In the past I retrofitted a travel trailer with 24v LiFePO4 batteries and an inverter, but all of the house wiring from the 12v distribution/fuse box to all the switches and lights were stock from the RV...
  • Looking for advice, doing a top balance after 2 years in storage (clean bus bars?)

    Hi guys, first time posting on this forum. I built 2 x 24v LiFePO4 batteries a few years ago, but sold that camper and disassembled. I'm now onto a new project and I'd like to start with a good top balance and had a few questions. I am pleased to report, that all cells appear to have...
  • New Travel Trailer Build, Solar Charge Controller Advice Needed (EPEVER, Tracer, XTRA, other?)

    Hi all! I'm building a new DIY camper and I'm looking for advice on a charge controller. I'm re-using some components from a previous build, but am buying some things new, thus some of my components are locked in, others aren't. I am open to any and all sound advice! We do plan on running a...
