All, I will do a load analysis for the 24v loads. I am looking to get around 800ah of LI storage at 24v. I typically use the larger 48v batteries from fortress. The space constraints will not allow for a wall full of small 50ah 24v units. I am not finding much selection of 24v 200ah+ options. Is sounds like most of the advice I am getting is towards not upgrading to 48v.
