I have a remote cabin with 5 kW solar, a 150V/100 Victron MPPT and Victron Lithium batteries with a 5 degree C charging cut off. When the temperature drops it's often sunny out, but the batteries won't charge due to the low temperature. Is it possible to redirect the MPPT power to some form of DC heater? Does the MPPT output turn off at 5C or is it the battery BMS that tells it to shut down? I'd like to redirect the DC power to warm up the cabin and ideally get it over the 5C cutoff to start recharging the batteries.
