Tristan, I have been following battery technology for 50 fifty years. First as a business consideration, then after retirement as
a home energy storage consideration. Around Yr 2000 I had 12kWh stored in lead/acid deep cycle. In 2021 I replaced them with LiFePO4 types. Left the rest of the system as is: Solar panels, MPPT charger, Inverter/Charger (line), but re-programmed charger(s) for LiFePO4 batteries.
This done because of the more favorable discharge characteristic of those over lead/acid, and almost maintenance free.
That system's life expectancy exceeds my own.
I started from the battery properties, chose the inverter after that, then the panels and the charge controller.
It's been there since 1999. I added a solar panel since then and changed the charge controller from PWM to MPPT.
The LiFeO4 batteries are MUCH different from the LiIon batteries (which would have never considered for storage.)
Learn the difference between all technologies and then decide.
