My Lithium solar batteries can't charge today while the sun is out shining brightly, because it's below freezing and I don't have battery heaters installed. They're in an outdoor shed so they can't burn down my house.

    I've learned a lot from reading RV forums and stuff like that. It's common to install DC-powered battery heating pads that run on relatively low watts to keep batteries warm enough to charge. I'll probably do that too.

    To keep a person warm, you'd probably need more power like at least 250-700 watts to run a heat lamp or small space heater. But that is easily doable with solar and batteries now.
