Overview

This is a daemon that will listen on a port for connections from a Ginlong Solar Inverter. Currently tested with a Solis 4G Mini Single Phase Inverter (Solis-mini-700-4G) running on firmware MW_08_0501_1.58 (Solarman-Ethernet protocol v5).

Thanks

graham0 for the inital script: https://github.com/graham0/ginlong-wifi dpoulson for the work on ginlong protocol: https://github.com/dpoulson/ginlong-mqtt

Details

The Solis solar inverters come with the option for wired or wireless monitoring 'sticks'. These are designed to talk to their own portal at http://www.ginlongmonitoring.com/ where the stats will gather. This software allows you to run your own gatherer on a server and push these stats into an MQTT queue for use in other systems such as the OpenHAB home automation software.

You will need a system running python with the following modules:

paho.mqtt.publish
socket
binascii
time
sys
string

You will also need a running MQTT server.

Setup

Log into the monitoring device, and configure the second IP option to point to the server that this daemon is running on. (Daemon defaults to port 10000) There's a hidden menu available at http://ip-of-data-logger/config_hide.html
Make sure that the MQTT settings are correct in the daemon.
Start the daemon
Add the following to your OpenHAB items (Replace XXXXXXXXXX with the serial number of your inverter)

// Environmentals
Number Solis_Temp "Temperature [%.2f °C]" (Solis) { mqtt="<[mymosquitto:ginlong/XXXXXXXXXX/Temp:state:default" }

// DC
Number Solis_DC1Volt "DC Volts [%.2f V]" (Solis) { mqtt="<[mymosquitto:ginlong/XXXXXXXXXX/Vpv1:state:default" }
Number Solis_DC1Amp "DC Current [%.2f A]" (Solis) { mqtt="<[mymosquitto:ginlong/XXXXXXXXXX/Ipv1:state:default" }

// AC
Number Solis_AC1Volt "AC Volts [%.2f V]" (Solis) { mqtt="<[mymosquitto:ginlong/XXXXXXXXXX/Vac1:state:default" }
Number Solis_AC1Amp "AC Current [%.2f A]" (Solis) { mqtt="<[mymosquitto:ginlong/XXXXXXXXXX/Iac1:state:default" }

// Stats
Number Solis_kWhToday "kWh today [%.2f kWh]" (Solis) { mqtt="<[mymosquitto:ginlong/XXXXXXXXXX/kwhtoday:state:default" }
Number Solis_kWhTotal "kWh total [%.2f kWh]" (Solis) { mqtt="<[mymosquitto:ginlong/XXXXXXXXXX/kwhtotal:state:default" }

These items should now be accessible in your rules. If you have influxdb and grafana set up, you should also be able to start producing graphs

Alternative setup

Set a static DNS entry in your router and point data1.solarmanpv.com and data2.solarmanpv.com to the server hosting this script.
Make sure to use port 10000 since this is the default port used by ginlong portal

MW_08_0501_1.58 - 476 length messages

Thanks for pointing me here @codeworkx! Gave this a spin. Small messages with the serial, firmware version etc seem to be decoded OK, but the "long" 476 length messages with most of the data I need seem to not be decoded.

Firmware version is MW_08_0501_1.58.

Some logs:
