So i wanted to get some opinion on setting up a separate system, 100W panel with a small battery that would run a heating pad for our Bigger 5KW LiFePO4 battery.
Our specs (48V 5.12KW LIFePO4 battery from signature solar, 48V growatt 5000es, and 4S2P, 2,280 Watt solar array)
We currently have an off grid cabin that we visit on the weekends during the winter months (November - January). So while we are gone during the week days, we want our batteries to be above 32 Degree Fahrenheit and charging.
Our first idea is to connect heating pad directly to our battery, but our battery is a 48V system and the heating pads are 12V. we could buy a step down converter but when the batteries die, and there are snow on the panels, the temperature will drop and everything would shut off until the sun clears the panels and the temp is above 32F to charge the batteries.
We thought it might be best to create a separate system, which runs off a 12V AGM battery, 100watt panel (Mounted at a steep angle). Is this over Kill to have a separate panel and battery for the battery heater? ive seen systems where they have separate system for a well pump.
Would love to hear some thoughts and what other people do during the winter months when they are not around.
Thanks,
