We have installed 2x quattro parallel with 24x pylontech us3000 and cerbo gx and 450/100 mppt and 2x fronius 8.2kw primo.
Battery information is only reporting 444A max charge/discharge rate where i would be expecting to see 888A if the cerbo is indeed seeing all 24 us3000.
We have 2x of the lv hubs and have tried many different configurations.
note: 2 hubs are installed to allow for future upgradeability.
The us3000s are arranged in 4 groups of 6 in 2x racks.
I have checked all dip switch settings and cables, all as per manuals.
Tried just 1 lv hub and all 4 groups connected to it, tried 2 hubs with 2 groups on each and hubs interconnected as per pylontechs manual with hubs addressed as per manual.
Still only seeing 444A.
Primos are currently off and only charging with the 450/100, the cerbo reports the mppt charging at 74A yet battery is reporting only 37A yet when i test charge current to each cabinet of 12 us3000, i am seeing 34A per cabinet which matches with the mppt output.
Batteries are staying alive so all 24 are communicating to the cerbo (i'm assuming)
Am i missing something here?
