Hi all

How many kW does my battery bank store? Would someone explain battery storage to a rookie?

I'm asking because I have 690Ah battery bank @ 24v that I decided to take for a spin before my panels are installed. My understanding is that 690ah x 24v = 16.56kW of energy to full depletion, 8.3kW at 50% depletion. However, per prior watt meter tests there's no way I've used 8.3kW since 4pm yesterday (I'd estimate < 1kW), but my battery voltage was at a critical 23.6v when I woke up this morning (Deca indicates 50% depletion is indicated at 24.2v). What am I missing?
