My power supply only goes to 30 vdc, so i hooked up the solar panel directly to the batteries and charged them up to 50 v, then switched back to charge controller. Now if I can just figure out where the shunt and BMS? Currently, the BMS is bypassing the shunt by connecting to the B- and P-.

Thanks

Had a few cloudy days where I live at below freezing temperatures, The controller worked and stopped the load on the batteries at 44 vdc. Later, I came home to a battery voltage of 24 V. The MPPT won't come back on now. The batteries are heated to 55 F. I was thinking of hooking up my power...

Hello All, I am just getting started so I have the first question. The 5048 Charge controller/inverter has a limit of 145 VOC input to either of the two controllers. I would like to attach 6 X 400 watt panels in a 3S 2P , which would give 149.9 VOC at the solar panel output. The manufacturer...
