I have what I consider to be a large battery bank, all LIFEPO4. I have six EG4 100 Ah batteries and eight 270 amp hour batteries for a total of 2,840 Amp hours or 581,632 nonimal watt hours. This has been in operation since 2024.
I turned off the six EG4 batteries and two of my 280AH batteries leaving me six 280 Am hour batteries on line. this is leaving me with 1,680 Amp Hours as an experiment to see if I can survive the spring/summer/fall seasons with reduced batteries on line, thereby saving daily duty cycles on approx. 40% of my battery bank. Batteries would only be a click away if needed and on full time from November through February when I need them the most.
I am hoping this will save my duty cycles on the more expensive batteries if I check on them once a month and charge them up if needed.
any thoughty?

Don't worry about duty cycles your batteries will age out before cycles a full lithium type battery cycle is counted 100% to less that 20% SOC if you have all of your batteries combined and only drain to 80% SOC and recharge back to 100% that is not considered a cycle count. My 6 server rack batteries are a year old and only have around 150 cycles on the counter they run the house every night until solar takes over the next day and recharge. At that rate in 20 years I will only have around 3,000 cycles on 6000-8000 cycle batteries. You paid alot of money for those use them as much as possible.
