Use Cases for System Design
By default, the gateway is connected to the
inverter through the RS485 interface.
Certain models provide multiple RS485
interface.
The RS485 interface of the third-party
controller is connected to the AUX interface
of the gateway, which is equivalent to a
direct transmission connection with a daisy
chain.
The gateway can be used as a Modbus/TCP server, connect
to a third-party SCADA system, and forward various
commands to the daisy chain.

Portal provides the flexibilities of
remote O&M.
Third-party servers can use the
open API of portal to develop their
own business systems.
