Aurora PVI Powercontrol
Feed-In Power Control using RS485 based Aurora protocol for PowerOne / ABB / Fimer Solar Inverters
This is supposed to run in the background on any Linux based computer (Tested on Raspberry Pi and Debian/Ubuntu).
Current value of electric power consumption (in watts / kilowatts) are recorded from any locally installed remote-read-out capable energy meter, the values are optionally filtered and then used to regulate the power output of any attached ABB / Fimer / Power One solar inverter using the Aurora protocol to exactly match the currently consumed power wattage.
This way, a zero-feed-in solar system can be realised.
The energy meter is attached using the ESP8266 based Tasmota Smart Meter Interface using any of the interfaces supported (D0 wired / infrared, Modbus etc.), the values are received via MQTT.
In case the MQTT or smart meter connection is lost, a watch-dog timer engages shuting down the solar inverter.
