It’s going to come where FIT will be in the negative atleast for part of the day. It’s already negative for wholesale providers amber electric etc.
Are you able to curtail a fronius symo inverter? Would you set the export limit to 0?
Is there a way to be able to do it via api or remotely?
Or what can be done to mitigate the amount of power you feed into the grid?
Chiming in a bit late here, but as I’ve done it - using Home Assistant automation platform I do have curtailment working for Fronius Primo, and I believe Symo uses the same MODBUS map. Uses MODBUS-TCP, so no extra cablign required, just hits the MODBUS API available at its IP address.
curtails by a continuously calculated percentage so the inverter follows changes in house load and solar output and tries to maintain a consistently minimal inwards or outward grid flow.
The Fronius details are embedded in https://www.smartmotion.life/2023/09/12/amber-electric-curtailment-with-home-assistant/?v=6cc98ba2045f which is worth looking at even if you are’t running Home Assistant
