Ok.. RV (trailer) came with a small system. I have upgrade all the hardware (panels, controller, inverter and batteries) but not the wires.
system consists of: 4 400w Trina panels, 4 100Ah BB lithiums, Victron 150\100, BMV712 smart, CERBO with touch 50 and a Xantrec 200 ProWatt. Everything works and does charge the batteries, BUT only once ever (last summer) it peaked at 1012w. I wasn't working on it or had made any recent changes to it. There are 1600w of panels, but they don't get much over 800 in any one day.. Could smaller gauge PV wires slow down getting more watts\volts..? The inverter wires heat up (after a few minutes of trying to pull 500w) because they're too small. (original inverter was 1200w) I'll share some pix. PS. The Lower controller and the Multiplus are NOT connected. I NEED an electrician to install the MP.
