PoC single solar panel system
#4
Make your string 7s20p, then you can put two strings together to make your 14s later on. I would go with 20p for the amp delivery.

Remember, the lower the voltage, the higher the amp draw. If you plan to use that UPS as an inverter, 980W @ 230V is 4A. Under surge conditions, that could be 8A (tho UPS's are usually not rated with a surge rating, so this is a guess).

With 10p, that would 0.8A per cell. For used cells, that's a bit high unless they are power tool high drain cells (which being 2600mAh I'm guessing they are not). The lower the amp draw on the cell, the longer it will last, both longevity and capacity. And that's the other reason for 20p vs 10p, as the battery bank will last twice as long as parallel determines ampacity and capacity. Series only determines voltage.
