Hello; Will, my name is Bruce F. I watched & enjoyed your live stream the other day. I learned quite a bit about you & I must say we agree a lot. But that is not why I am writing. You pointed out it's "DIY" solar and your enjoyment is seeing other peoples build ideas. So my way of thanking you for all I have learned from you is to share mine. I have included 6 photos.
Problem; I have a off grid cabin in the woods of Maine. I use solar for power thanks to you. But how do I keep the batteries warm enough to be able to charge in winter when gone for months at a time.
Solution; I took a old cooler I had & set it on a $7 dolly from harbor freight, #1.
Drilled a couple holes for cable, photo #3.
Attached 200w inverter & current meter photo #4.
Also added temperature gauge & power meter photo #5
lined in side with bubble wrap & foam board, then put in DIY battery and a car push bulb light assembly under $10 photo #6
When bulb is lit its consumption is only 7w. It generates enough heat to keep cooler well above freezing 40 to 60 degree range all winter photo #7
Problem solved, hope you liked.
PS: Simply Safe Alarm System $250 runs on 10w consumption and uses cell tower transmissions for communication. So for about 25w consumption rate you can have a warm battery (ie power when your there) & alarm system for your off grid cabin when you're not.
"Note" Use BMS with low temp cut off incase bulb burns out.
Thanks Again
