Configuration

CATCH Solar Relay can participate in a MODBUS RTU control system. The Modbus
interface is implemented over an RS485 physical layer. All aspects of the relay can
be updated, and controlled via the Modbus interface. For more information about
using Modbus, visit the tech docs section of our website.

Modbus Configuration

Modbus Device Id:

The unique device id for

this device on the Modbus. This can be a
number between 0 and 255.

Baud Date:

Baud rate in use on the Modbus.

Stop Bits:

Valid values are 1 or two

Parity:

Valid Values are even, odd or none.

IMP

OR

TANT

The CATCH Solar Relay implements
inverter control using the RS485 Modbus
interface. My details on how to configure
your inverter and the CATCH Solar Relay
can be found under the tech docs page of
our website. www.catchpower.com.au
