V3.80~33 Victron triggers SolarEdge Power Limiting via Modbus

Beta testing

Hi,
I’ve been using Solaredge’s modbus TCP connection for a while on several of my installations, without issues.
Now, with V3.80~33, The Cerbo is limiting the power of the solaredge to 0.

  • Happens irrespective of DESS being on or not
  • Happens irrespective of NodeRED sending any limit value.
  • V3.75 has no issues and the solaredge works fine.

Solaredge support helped to confirm the signal comes from Victron’s modbus connection.

I can confirm the behavior on my system as well. Working on 3.75, but as soon as I switch to the v3.80~33, in home assistant it shows: I_STATUS_THROTTLED and output is 0W.

Seems to be fixed with v3.80~36, testing now
