Hi all,
I’m new here and just feeling my way around and moving to upgrade to a DIY lithium battery build.
Anyhow currently have a 48 V system with 8 6 v lead acid 200 ah batteries. We installed the system a little over three years ago and I really noticing some performance drop. We have done some testing and with pretty much everything is shut down at night except for a few timers on some appliances we lose about 7% charge our system usually shuts off with our batteries reading right around 68% we have been through our charge controller parameters and they all seem to be set fine we have been pretty careful and it really never run our batteries past 50% I was wondering what other tests I might be able to run for the batteries or are they just getting too old. When they were installed the solar company we used suggested we would get 6 to 8 years out of batteries. This seems drastically short are batteries also never read 100% state of charge anymore. We would love to get another one or two years out of this before I switched li-on but that doesn’t seem likely I truly appreciate if anyone has any ideas of tests we can use to diagnose problems or ways to get some more performance. Thank you so very much
