victron 3phasen -> Batrium BMS

Hallo,

ich habe heute meine ersten Geräte aktiviert:

3x Victron Multiplus II 5000
1x Cerbo GX

Soweit so gut, ein Problem stellt sich mir in den Weg...
Die rote LowBattery Anzeige blinkt obwohl ich 53V anliegen habe...

ESS (Energy Storage System) (size:985)
*) System uses LiFePo4 with other type BMS
(This can be either a BMS connected via CAN bus or a BMS system in which the
batteries are protected from high/low cell voltages by external equipment.)
*) The battery capacity of the system is 608 Ah.
*) Sustain voltage 50.00 V.
*) Cut off voltage for a discharge current of:
0.005 C= 52.00 V
0.25 C= 50.00 V
0.7 C= 49.20 V
2 C= 48.00 V
*) Inverting is allowed again when voltage rises 1.20 V above cut-off(0).
*) Relevant VEConfigure settings:
- Battery capacity 608 Ah.
- PowerAssist unchecked
- Lithium batteries checked
- Dynamic current limiter unchecked
- Storage mode unchecked

Total size of all assistants including the required
(hidden) system assistants is: 1044
