By code, the frost line is 48". It could be possible to bury the lines and the box just outside the foundation. Perhaps within a root cellar (yet to be built).
I see there are 24v, 200Ah batteries for around $1100 (SOK) to $1500 (EG4) each. Now I get messed up on the math. If I use two of them, am I getting 24v at 400Ah or 48v at 200Ah? Which is better?
So looking at this from the idea of buying separate components, I want to make the following assumptions on electrical requirements:
While occupied:
Mini-fridge (100 watts?)
A few LED lights
Charging electronic devices (phone chargers, maybe a laptop)
Charge batteries for overnight backup...
I need your recommendations.
I'm looking to install solar with 48v battery storage in northern Wisconsin. The scenario:
This is an unattended, non-climate controlled building (occasional use cabin)
Weather service data shows that more than 50% of the days have had a low temperature below 35F...
