Jay,
With the SimpliPhi's we've been installing we require a
shed on slab, walls R-21, roof, R-38 and then the smallest propane wall
heater (they use zero power to operate) we can find and set it at 55
degrees. No need for the insulated box or fretting about toasting $20K+
in batteries. It would be nice to find one with a thermostat that goes
down to 45 degrees.

HI All,
As I get more calls for offgrid designs with lithium batteries I”m wondering
what you all are doing to keep the batteries warm when it gets cold. For some
of you 0 F will seem mild, others super cold.
Doing a battery box and heating that or heating the whole inverter/battery shed?
I’m definitely not looking at batteries like battle born with the built in
heaters.
Simpliphi, Discover, some of the newer server rack ones ( UL listed), etc.
Thanks in advance
Jay
