The problem with that is what if the main charging system is not producing power, because it is covered in snow, or it may heat the batteries at night (which you may or may not want). If you connected it to the same bus as the main SCC. I would not want the heaters to drain the batteries when I can't get to my cabin to clear the snow. For me this could be months.Yes. Although the main charging system should power the heaters even if the BMS blocks charging.
Is the "load" port on SCC isolated from the battery, if so that would work. I guess you could put a blocking diode into the run from the SCC to the battery so the batteries can't power the heaters. I could just put a switch in to not heat the batteries when I am not there as well.
I am just working through the planning for my off grid cabin for this summer.
