I’ve got a pair of 9.5Kwh Givenergy’s and yes I could avoid emptying completely by setting a limit. However I don’t want forced export to reduce the performance of my battery over time.
Givenergy 9.5, allows for 100% DOD, preferably 80% – 90% and unlimited cycles at 80% DOD without compromising the battery’s lifespan however, what they are saying here is, life cycling at 80% DOD is equal to 6,000 cycles backed by the guarantee, which works out at 500 cycles per year, so you should be fine.
