Hi community, I am very new to ESS. I want to build a system myself using multiple battery packs and Vitron devices. I live in the northeast part of America, which is fairly cold, below -10 during the winter.
I want to use the LifePO4 battery because its price is more friendly than Li-ion. And I want to put the whole system in the garage. However, like most houses in NA, the garage is not insulated. So it will get -10 Celsius easily.
I heard that LifePO4 will go dead below -20c. So, should I go for the Li-ion battery? Or, should I move the system indoor, like the basement? Maybe it is fine. Any comments and suggestions are appreciated.
