Are Pylontech US3000c batteries good for Off Grid Living??

Going on 18 months since moving off grid with the family, everything from my home office to hot water to Ovens rely on the battery bank, I would have a mutiny on my hands if TV's and xbox's did not function. We have been running a bank of US3000C Pylontechs.... how have they stood up so far? #offgrid #renewableenergy #solar #solarpower #livingoffgrid #lifepo4 #pylontech
