Solis inverter Ginlong import for Node-Red
This will listen for the output of the Ginlong Wifi stick, connected to a Solis inverter. It will then extract and format the data from the received string and output it to a text file, but you can change the output to go to a database of your choice.
Please note this works for firmware version: H4.01.51Y4.0.02W1.0.57(2017-07-261-D) on a Solis 4G inverter.
You can send the output of the wifi stick to alternative locations under Advanced -> Remote server in the stick's wifi interface.
