Solar Inverter Ginlong Solis Mini 700 4G

Post by Toulon7559 » Friday 08 June 2018 14:56

As 'gapfiller' in my PV-configuration I purchased a (secondhand) solar inverter make/type Ginlong Solis Mini 700 4G.
For monitoring of that device in an simple way, I could either use an external energy-meter, or the Ginlong WiFi-stick related to the proprietary Ginlong Monitoring system.
The 1st choice is OK for externally, very straightforward reading the PV-production-information, by addition of a DIY measurement-configuration of kWh-meter with S0-interface and optional RS485-interface, linking to a readout by e.g. Domoticz.
The 2nd choice may be more interesting giving also 'internal' information. It needs investment to a company-solution and related, additional DIY read-back like described in this thread.

I would like to avoid the use of the Ginlong-servers, because it is just an extra part in the chain.
Has anybody seen (or has available) a 3rd option solution which directly reads the RS485-interface of the inverter by means of a lua-script or Python-script?
Set1 = RPI-B+RFXCom433+S0PCM+Linksprite-shield for BMP180/DS18B20/RS485+DDS238ZN1
Set2 = RPI-3+RFLinkGTW+ESP8266s+PWS_WS7000
Common = 2*PVLogger+PWS_TFA_Nexus+KAKUs
=> Energy & Data Management based on Time and on PV&Consumption&Meteo

(Not with help of Ginlong) some Basic protocol information for the 3rd Option seems to be at https://github.com/graham0/ginlong-wifi/issues/5
But no luck for a 'progressed' script.
Choice therfore seems to be to buy a datalogging stick for Option 2, and then to apply the solution described here.

But no luck for a 'progressed' script directly applying the RS485-interface, dissecting the modbus-datastream, and compile an upload to Domoticz:
lot of homework to be done .........
Takes some money, but most practical & quickest choice therefore seems to be to buy a datalogging stick for Option 2, and then to apply the solution described here.
