The inverters communicate via UDP protocol, by default running on port 8899. They use a native 'AA55' protocol and (some models) ModBus protocol. ET inverters support both protocols, some inverters may not support both of them.
This documentation is based on experiments and v 67BA arious sources (see below). Thus it is incomplete and may contain errors.
An inverter in the local network can be discovered by a UDP broadcast to address 255.255.255.255, port: 48899, message: WIFIKIT-214028-READ
On success, the inverter responses with it's IP address (as a text string) followed by it's WiFi AP name.
A more reliable way to access the inverter may be to access it directly by it's IP address assigned to it by a DHCP server.
