I ran several more tests and the behaviour is consistent:
-
When I remove all Assistants, the system immediately starts exporting normally on all phases (same as my second PV with identical setup, where everything works).
-
When I enter parameteres in ESS assistants back with the exact same settings as on the working system, the setup gets stuck again:
– Only inverter #1 works,
– Inverters #2 and #3 stay in passthrough,
– The system always imports from the grid, no export on L2/L3.
CT readings and internal/external measurements are correct.
The issue appears only when Assistants are active.
My goal is to use as much PV production as possible on-site, not export it on a single phase where the load is low.
I need inverter #2 and #3 to operate normally with Assistants enabled, but this currently does not work.
Adding screenshot below - exporting #L1: -758 W when I need #2L: 148 W and #3L: 446 W ?

Does anyone have an idea what could be wrong or what else to check?
Thanks in advance
