Overload L1 on VE.Bus System [276]

Hi,

Recently installed my Victron system (1x MultiPlus-II 48/5000/70-50, 4x Pylontech US5000-1C - 48V 4.8kWh, 1x Cerbo GX MK2, VM-3P75CT energy meter)

I have 3 fase grid 25A. My Victron is connected via AC in on L1. I don’t have anything on the AC out.

Every Saturday, when my wife starts to get cooking and fires up all possible appliances at the same time, I get multiple Overload messages. I don’t understand why the Victron tries to give more then it’s capable of or even how to understand this error message. Any help or ideas would be appreciated!

In dynamic ESS I have the following configured:

  • Can you sell energy back to the grid? Yes
  • Maximum import power: 17 kW
  • Maximum export power: 17 kW
  • Operating mode: Green mode
  • Battery energy capacity: 18 kW
  • Maximum discharge power: 4 kW
  • Maximum charge power: 4 kW

In VEConfigure I have these settings:

  • General
    • 50Hz
    • AC input limit: 25A (Overruled by remote)
    • Enable battery monitor: Yes
      • State of Charge when Bulk finished: 85%
      • Battery Capacity: 400Ah
      • Charge efficiency: 1.00
  • Grid: Belgium C10/11 ed.2.1:2019-09
  • Inverter
    • output voltage: 230v
    • DC input shutdown: 44V
    • DC input low restart: 48V
    • DC input low pre-alarm: 48V
  • Charger:
    • Enable Charger: Yes
    • Lithium Batteries: Yes
    • Charge current: 25A
  • ESS Assistant
    • LiFePo4 with other type BMS
    • battery capacity: 400 Ah
    • Sustain voltage: 48V
    • Cut off voltage: 46V
    • Inverting is allowed when voltage rises: 1.2V
    • PV Inverters on AC out: No

In the console I have these settings:

  • Multiplus: Grid current Limit: 25A
  • AC input 1: Grid
  • Position of AC loads: AC input only

    • Minimum SOC (unless grid fails): 20%
    • Limit inverter power: off
    • Grid setpoint: 50W
    • Grid feed-in: AC-coupled PV-feed in excess
    • Peak shaving: Always
      • Limit system AC import current: Yes
      • Max import current (per phase): 17A
      • Limit system AC export current: Yes
      • Max system export current (per phase): 17A
    • DVCC: shows ‘forced on’ but disabled.
      • Limit charge current: off
      • Limit managed battery charge voltage: on
      • Max charge voltage: 55V
      • SVS - shared voltage sense: Forced off (disabled)
      • STS - Shared temperature sense: Forced off (disabled)
      • SCS - shared current sense: disabled
      • Controlling BMS: Automatic selection
      • Auto selected: Pylontech battery
