DTUProController

Hoymiles DTU-Pro zeroexport controller for 6 Microinverter. Beacuse of the bugs in the Hoymiles DTU-Pro, while doing zero export, I wrote this python script for controlling the Hoymiles DTU-Pro for a "real" zero export.

Data Logger and zero export Controller for Hoymiles DTU-Pro / Microinverter MI1500,MI1200,MI600,MI300,HM1500,HM1200,HM600,HM300,TSUN TSOL-M800 series over RS485/ModbusRTU This script controls zero export power to the grid over DTUPro, monitoring over mqtt/nodered

usage: *.py Controller=0/1 [1=controler&datalog] [0=only datalogger], Output=1/0

dtupro_ctrl.py 1 1 ; script running as zeroexport controller , no output to the console

dtupro_ctrl.py 0 1 ; script is running as datalogger/no zerp export , output to the console

What do you need:

SET !! DTU-Pro as Remote Control/Modbus Protocol
SET !! DTU-Pro RS485 device number to 101 or change it in script
SET !! DTSU666 grid meter device number to 22 or change it in script (DDSU666 or whatever CHINT compatible is also ok)
SET !! Registeradress in dtudtsuregister.json, if you have another Gridmeter
for RaspberryPi or PC get a USB/RS485 stick
connect DTU-Pro, DTSU666 and PC or Pi over RS485 twisted pair (take care of A/B)
install python3
install pymodbus
install MQTT mosquitto
install Node-Red, if you want to use my Node-red functions for data-graphics
CONFIGURE "dtupro_ctrl.py" in script under CONFIGURATION
start the script in terminal
if you want to handle have more than 6 inverters, set it in script
