wamcneil Posted March 12, 2021 Share Posted March 12, 2021 Hi all, I've got what might be a crazy idea. The problem: My batteries are waaaaaay at the back of the coach right-rear. But my inverter is up forward on the left. 4/0 cables between, but still a lot of voltage drop at high current. No easy way to fix this, unfortunately... Moving the inverter closer to the batteries has entered my mind, but then I'd need to re-route a lot of wiring.😞 What if I replaced the inverter with a 24v inverter? Dropping the current in half should get my voltage drop down to the 3% range. Other than the obvious voltage change, a 24v Magnum inverter/charger would be plug-n-play swap for the existing MS2012. Solar controller can run 12v or 24v, so that would only be a dip switch setting. It would be pretty simple to separate the 4/0 cable run from the high-current run-bay and repurpose it for 24v, then wire the existing house batteries in series for 24v Magnum AGS is good with 12v or 24v I've got enough room on top of the batteries to install another 12v battery for the house loads and run cables back to the high-current run bay to feed everything except the inverter. Add small 12v charger or 24v/12v converter for new house battery Anything I'm missing that might make this plan end in sadness? I remember needing to connect the neg inverter cable to the chassis and the neg battery cable. I suppose I'll need to connect the new 12v battery neg to the chassis when I disconnect the inverter from the chassis. Thanks, Walter Link to comment Share on other sites More sharing options...
