I think this is quite a common point of discussion, but I need just need some confirmation that I understand correctly.
This installation is as follows:
- 2 x Multiplus II 5kva 48V units set up in single phase parallel
- CCGX unit
- 4x Pylontech US3000 modules
- No solar array installed as yet, purely back-up.
Setup and settings done exactly as per https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom
System was commissioned today and seems to function normally, except for a "Battery monitor (512)- High voltage" alarm.
Battery is at 89% SOC with voltage at 51.81V
Batteries were reasonably discharged (66% SOC) when turning on the system for the first time, so it stands to reason that they might have been standing for quite some time before we received them.
Am I correct in saying that this is a cell balancing issue, and should self-rectify? Or is there something I am missing?
Thank you in advance
