Use assistents to Ignore ac

We are using a 3f multiplus 3000 setup with mppt’s for solar coordinated by a cerbo gx.

We would like to ignore ac when the load is lower then 2000w or when soc is higher then 30%.

And connect to ac when load is higher then 2500W or when soc is lower then 15%.

Therefore we tried the following but it looks like it doesn’t work:

  • Programmable relay (size: 198):
    Use General Flag
    Set relay of:
    In case of a general system failure
    When load higher than 2548 Watt for 10 seconds
    When SOC lower than 15%

  • Programmable relay (1) (size: 53):
    Use General Flag
    Set relay on:
    When load lower than 2000 Watt for 10 seconds
    When SOC higher than 30%

General flag user (size: 5):
Use general flag to ignore AC Input 1

Total size:
Total size of all assistants including the required (hidden) system assistants: 327

Anybody any idea what i am doing wrong?

The way they are set up both have to be true for the condition to happen. (And logic)
If you want a connection with a
Either or, then separate them into 4 assistants.

On a three phase though it becomes more interesting as usually it is the master that decides. Do you have 3 phase loads/appliances?
