My Battery is turned off, as well as the furnace, refer, water heater, fans, lights, inverter- all are turned off. My panels ARE connected serially and will go as high as 82 V or 32 amps, that's why the 40 Amp MPPT controller. You get much more power from serial connections, especially in poor conditions, but you have to have the proper controller.
My inverter is the 1800 watt Xantrax. There is a little control switch behind the driver's seat, and it is turned off. But here is the strange thing - when I turn the battery off, and the inverter is off, I can turn the battery back on and the inverter fan starts and runs a few seconds, and the inverter is still turned off.
I bought a DC amp meter and am going to test for discharge. I hope I find something. The electron bucket is leaking!
Thanks for all the help!
