Concur about vagueness... what does this mean?
Does it need to be depleted to 60% to store or that it will go down to 60% after 5 years???
1% . onht = 12% / yr = 60% dod after 5 years...
Great post Simon (Karrak)
I run about the same sized setup as you. 300Ah 24v LIFEPO4 (Sinopoly) 8 cells in series and 1400 watts solar 5kw inverter, Cellog 8. Installed 2013 and was a bit of a leap of faith.
My settings have been the same since installed, approximately the same as yours. Cells 2.95v - 3.45v. Pack 24v to 27.4 volts and I manually top balance every 6 months or so (which is never out much).
So far so good, haven't noticed any drop in performance over the years.
The cellog disconnects my inverter if needed via the output alarm and works fine. My battery monitor (voltronics) gets a bit out of wack if I don't reach 100% SOC for a few days, which is frustrating and means I have to rely on voltage monitoring.
Good reassurance for me to see your settings are similar.
Simon, on the minimum voltage line the last value in the string is 1.795, was there a problem with that cell, it is also reflected in the delta voltage difference, or am I misinterpreting the numbers?
