Where is the temperature sensor mounted for my Easy Solar 48v system? Or is it mounted inside my BYD Lithium battery box? My problem is in the winter, when the shed temperature is lower than 15 deg C and I'm running the generator, then the sun comes over the hill, and my solar panels' charging capacity is throttled back, due to the low temps. I'd like to install a small heat source, say a 100w light bulb, running off the generator output, to warm the system up enough to make the most of the brief winter sunlight.
Another question: Do lithium batteries need this low temperature protection? Is it possible to adjust the temp threshold down a few degrees?
