Sure thing. First, make sure the battery management system is actually tracking each cell’s state, not just the aggregate. If it’s averaging, the high‑voltage cells will stay full while the low ones die. Next, pull the load off the inverter during low‑sun periods—those micro‑loads add up. Try a trick: swap out the “deep‑cycle” cells for a few higher‑capacity ones; the extra amp‑hours give you a cushion. And don’t forget the trick of running a small charger at night; it’ll top off the cells when the generator’s idling. Finally, keep a log—if the cells still lag, it might be a subtle wiring fault that only shows when you’re looking for it.
