I recently added two more Revov R100 batteries to my solar installation.
Currently running the following:
2 x SunSynk 5kw inverters in parallel
4 x Revov R100 (100 Ah each) - 2 batteries are just over a year old, and 2 new batteries added.
Everything is connected to Solar Assistant which enables me to see the details of each battery.
After about three days, the two older batteries are on nearly the same charge, and the newer batteries are much less. (See pic attached).
I also include a wiring diagram to indicate how the batteries are connected.
Is the difference in the state of charge normal, or am I missing something here?
