I've been off grid since 1985 and, of course, started and continued with flooded lead acid batteries. My 24V system currently produces 4-5 KWH per day which is stored in 20 6 volt golf cart batteries and supplies our need with minimum back up generator operation during the winter months. At current prices, my battery bank costs about $110 for each battery and a bit over $2200 for total replacement. I have always replaced the batteries individually as the cells lose specific gravity numbers. The batteries generally last about 7 years.
I'm giving some thought to upgrading to the new lithium batteries that so many of you use.
Two questions: What would be the approximate cost of replacement of my current batteries? Would the summer heat in my PV shed (100+ degrees occasionally) be a deterrent to using the new batteries?
