I am working on an off-grid solar project, and I need to store the energy my solar panels produce in batteries. I will use sealed lead acid batteries because they require little maintenance and are less expensive than lithium batteries.
Lead acid batteries perform optimally at a temperature of 25 Degrees Celsius. To save money, I will build an enclosure for my batteries using wood. Since I am off the grid, I do not have a HVAC system installed. I will have a fan and a space heater, but these heat and cool unevenly.
How should I go about storing my batteries so that they do not experience temperature extremes and are properly ventilated?
After accounting for losses due to inefficiency, to meet my energy requirements, I will use 12 Crown 6CRV220 batteries. I will 3 sets of 4 batteries in series and wire all 3 sets in parallel. The entire battery bank will be 24 V and 660 Ah.
