The OEM manufacturer and model is EWAY-VNV6204. Eway makes more power electronics such as car chargers. There are a couple more models in this series such as the EWAY-VNV6208 where the last number corresponds to the wattage. | The OEM manufacturer and model is EWAY-VNV6204.

What is really neat is that the MCU responsible for network connectivity is an ESP32-C3 which I am familiar with. Moreover, it has a 4-pin header right next to it which is most likely UART and a physical push button labeled "BURN" which may very well be a button to put the ESP in flashing mode. | |||

I bought a solar power set from the Lidl in Germany for just 200 euros. A decent deal for 370 Wp panels, a microinverter and some mounting brackets.
On problem: the microinverter runs Tuya, which is notoriously connected to Chinese clouds. The inverter can be used without setting up network connectivity and the Tuya app, but I would like to have stats from this device in Home Assistant.
So let's hack it!
