First

This repo is no longer being developed. (I had to switch to a Hoymiles Inverter because Deye lost a needed certification and was broken...)

but still Thanks...

• ...to @jlopez77 https://github.com/jlopez77

This is a fork from jlopez77/DeyeInverter

• ... to @fjcarretero https://github.com/fjcarretero

• ...to @xtheone https://github.com/XtheOne

for the initial work and code in the origin Repo

and aswell

• ...to @jmccrohan https://github.com/jmccrohan for his lighwight Solarman Scan utility!

DeyeInverter

Small utility to read data from DEYE Micro Inverters with integrated Wifi Modules.through the Solarman Datalogger.

Tests indicate that the full ModBus is available through the TCP connection.

Probably this can lead to modifying Inverter Configuration via TCP calls.

Tested and works with

Deye SUN800G3-EU-230 Micro Inverters

• Logger SN: ++ 39xxxxxxxx ++ 41xxxxxxxx
• Inverter SN: ++ 22xxxxxxxx ++ 23xxxxxxxx

Scan for Logger

python3.x deye_scan.py

Configuration

Edit the deyeconfig.cfg and enter the following data:

[DeyeInverter]
inverter_ip=192.168.X.XXX
inverter_port=8899
inverter_sn=41xxxxxxxx
installed_power=XXXXX #power in Watts e.g. for 4.5kW write 4500

Run

python3.x InverterData.py

{
    "Running Status()":4,
    "Daily Production(kWh)":0.1,
    "Total Production(kWh)":3.3,
    "Total Production 1(kWh)":1.6,
    "Total Production 2(kWh)":1.6,
    "AC Voltage(V)":234.0,
    "Total AC Output Current(A)":0.1,
    "AC Output Frequency(Hz)":50.1,
    "Total AC Output Power (Active)(W)":30.0,
    "Inverter Temperature(Cº)":12.2,
    "PV1 Voltage(V)":26.0,
    "PV1 Current(A)":0.5,
    "PV2 Voltage(V)":28.2,
    "PV2 Current(A)":0.5,
    "Grid Voltage Upper Limit(V)":275.0,
    "Grid Voltage Lower Limit(V)":180.0,
    "Grid Frequency Upper Limit(Hz)":52.0,
    "Grid Frequency Lower Limit(Hz)":47.5,
    "Installed Power(W)":3.8
}

Use with Domoticz

Create Virtual Devices in Domoticz (look at domoticz_sample.config)

and let the Script run every 5 minutes. (Example with Cron)

Known Issues

The inverter is not fast enough to answer, you can get timeouts if you query it too often.

Contrib

Python is not my strengh - also the BASH Script wont be the nicest, both both do its work.
