Does anyone have the BMS communication protocol for the HY5.0 Gen 1? I'm trying to understand the inverter-side BMS interface for protocol analysis. Specifically, I'm looking for the electrical interface (RS485/CAN), baud rate, addressing and the inverter's battery discovery/polling protocol. I have a HY5.0 Gen 1 but no GivEnergy battery, so I'm trying to establish what the inverter expects to see from a battery.
