Word of warning. My folks have had a standalone solar system using flooded lead acid batteries for about 10yrs now. Decent sized system all professionally installed and properly vented. My father has been monitoring and maintaining it for a decade. I was over there the other afternoon and he went out to the battery room to check the batteries like he has 1000x before. We heard a big BOOM. Two batteries let go in his face. We think the static from his clothes triggered a hydrogen explosion. He got drenched in battery acid, a few cuts and burns, and hearing loss but is otherwise okay. He'll need new glasses as they got destroyed. He had his own personal mini chernobyl.
