GoodWe Inverter

I tried to create an implementation for the DT series. As far as I can tell it is pretty similar to ET except other prefix and command codes are used. I adapted a bit the code for ET to keep as much as possible common, I renamed the EtProtocolCommand to ModbusProtocolCommand because that's what it seems to be. I managed to find quite a lot of the sensors by comparing to SolarGo app (which works with my DT inverter), sniffing traffic and guessing (still not sure about the Running Hours since I can't view it anywhere in the app or on the device). I also managed to enable the setting of the …

It's not possible to do it for `EnumBitmap22` and `EnumBitmap4` because the labels list does not contain all values (tested on my GW10K-ET).

I have a new EH inverter and it seems I can connect quite well with it using the same protocol as the ET series. By extending detection of the model on the serial number (containing "EHU"), I have good communication results. I am not using Home Assistant so that I only use the Python class.

I had the same issue! It depends on your Inverter if you should use the WIFI/LAN Kit 20 or the WIFI/LAN kit GA10081-69-00P. Wifi/lAn kit 2.0 should be used ET Series 15 and higher. Below you should use Wifi/Lan Kit. Anyhow, i have a GWK8ET+ and also by mistake the WIFI/LAN KIT 2.0. Which works fine upto a certain device FW. With V4.00 it works. As i updated it with SolorGo to V106075.00 i had the same issues like you. I reched out to Goodwe support and the downgraded my WIFI/LAN Kit 2.0 back to FW 4.0. As per today nomore issues

Hk1000 is a smart meter attached to your electricity meter to show how much solar you are producing, energy consumption from solar and grid and how much you are sending it back to the grid. The inverter only shows you how much you are producing.
