I am currently making a final decision between Rolls Surrette 2v 5000 series cells and Pylontech 3000c’s for my battery bank. My daily power budget is 25kwh and the battery bank will be sized for two days of autonomy. If I go the rolls route I would be using 24x 2v Cells 2190ah each for 113.9kwh 56.9 usable at 50% DOD 28.4kwh Per day. On the Pylontech side I would use 16x 3000c’s 3.3kwh usable for 53.3kwh usable, 26.3kwh per day. Just for context this will be tied to two sunny islands in split phase a 21kw solar array and a auto start diesel generator with 250 gallon fuel tank. Generator would auto start around 45% dod for the lead acid and 85% for the pylon just to be conservative. Everything will be housed in a temperature controlled solar room 25c 24/7 365. Now my main concern is long term reliability of of the system this will be 100% off grid primary residence. In terms of cycle like rolls are rated at 4200 at 50% did while pylon are rated at 6000 at 90% dod. My main concern with the Pylontech is unknow calendar aging and reliability long term of the bms. I’m looking to hopefully get around 15 years out of these batteries. Any opinions?
