We highly recommend using the RS485 connection for the GoodWe inverters. The Modbus TCP connection is available but not recommended at all, we do not provide any support for this connection. Furthermore, curtailment is only supported via RS485.

If you have multiple goodwe devices it is possible to change adresses seperately for each device. Or you can daisy chain them. (https://docs.eniris.be/wiring-best-practices/#wiring)
