I'm in the beginning stages of planningmy 48vDIY powerwall (harvest/used 18650s). I'm thinking of putting them in an enclosed rackmount server cabinet and placing thatin my detached garage which is not insulated. The garage walls are made up of6 feet of cinder blocks (pony wall) then 2 feet of woodframingthat meets the open rafters (all wood).I'm in Seattle, so we're looking at a typical range of low 40's to high 70's degrees Fahrenheit with once in a while extreme temps at mid 20's and high 80's, respectively. On really hot daysI've measured the garage's temps to beabout 5to 7degrees hotter than outside.
Based on this setup and considering insulating the garage might not be an option (insulating over the concrete perimeter would make this 2 car garage, a 1 car garage),what's the next best thing I can do to help prevent the powerwall's performance from suffering during the colder and hotter temps??
P.S. - The solar panels will likely be installed on the garage roof, that's why I'm thinking of placing the powerwall in the garage. Also for safety reasons, in case the powerwall catches fire (yes, I will be fusing the battery, but still,you never know) - that building would possibly burn down, but not the house.
P.P.S. - The reason I'm thinking of building the powerwall in a rackmount server cabinet is thatthe steel enclosure would hopefully better protect it and/or contain itin the event ofan earthquake (instead of flying off the wall in a wall mount setup). Plus I can get cabinets for as low as$50 andthey're 28" deep which means more cells in parallel and longer battery run time.
