There is a residential solar system I want to model using a building energy simulation tool. Considering the building electricity consumption, I've decided to use seven 256 W panels and my battery capacity is 1100 Ah considering two days of autonomy, 60% DOD and 24V operational voltage. The problem is when I want to define the battery specifications for the software, it requires fully charged and fully discharged open circuit voltage for the battery. I've been searching different battery data sheets but I can't find the data. Does anyone know how they can be estimated?
