I am busy to calculate an off grid system with PV panels in combination with 2 LFP batteries of 300Ah
It is for a vacationhouse without power in the north of Sweden, around Östersund
Because we are mostly there during the summer I am intent to disconnect the LFP and store them in the house during the winter.
But is it possible to store a LFP while it freesing around ? House is not heated during the winter and it can freese around -20°C
If not I have to take them back home or find an other solution.
