I have a Solis 5K-G Single Phase Inverter with a Ginlong LAN stick. This stick logs statistics of this inverter every 5 minutes to the Ginlong monitoring pages.
Ginlong Solis Inverter
I want use those statistics on the Ginlong site for my own analyses en domotica. To get those statistics to my own systems I created a python script that scrapes PV and inverter statistics from the Ginlong monitor pages every 5 min. And then outputs it to influxdb, pvoutput and/or mqtt.
Possible it also works with the following inverters: Omnik Solar, Solarman and Trannergy inverters, they are using the same kind of stick. Let me know.
Install
Go to https://github.com/dkruyt/ginlong-scraper and clone/download the ginlong-scaper.py script.
Install necessary python modules.
pip install paho-mqtt
pip install influxdb
Adjust the config. Set the outputs that are not needed to false.
# solis/ginlong portal config
username = 'user@name' #your portal username
password = 'password' #your portal password
domain = 'monitoring.csisolar.com' #domain ginlong used multiple domains with same login but different versions, could change anytime. monitoring.csisolar.com, m.ginlong.com
lan = '2' #lanuage (2 = English)
deviceId = 'deviceid' # your deviceid, if set to deviceid it will try to auto detect, if you have more then one device then specify.
### Output ###
# Influx settings
influx = 'true' # output result to influx set to false if you dont want to use
influx_database = 'dbname'
influx_server = 'localhost'
influx_port = '8086'
influx_measurement = 'PV'
# pvoutput
pvoutput = 'true' # output result to pvoutput set to false if you dont want to use
pvoutput_api = 'apikey'
pvoutput_system = 'pvsystem'
# MQTT
mqtt = 'true' # output result to mqtt set to false if you dont want to use
mqtt_client = 'pv'
mqtt_server = 'localhost'
mqtt_username = 'username'
mqtt_password = 'password'

Create a cron entry, every 5 min is ok, because the inverter logs also every 5 min.
