I am having an issue with one of the batteries we have in the installation. Its a us3000c, it keeps giving an internal comms alarm when vied on batteryview. when discharged, when the inverter usually switched over to main, the other batteries in the system are working fine, just this US3000c. can it be the battery only has 1400 cycles. and the cells are all fine. Can this be a firmware issue on the battery this battery was bough 5 years ago. the us2000c is still working perfectly.
