My friend has 12 AGM gel led acid batteries 1000 Amp hr, 24 Volt system, each cell is 2.25 Volt and this bank cost him $8,000. He reckons he will get 15 yrs from batteries, assuming you do not cycle them below 80% fully charged, this might work OK. But for the same price, I can take Nickel Iron down to 20% fully charged, no problems with battery chemistry life. And I will get 100 years of life.
