4.2 DRM Connection/ Logic Interface Connection

The AS/NZS 4777.2:2020 requires inverters to support demand response modes (DRM).
Solis Australian version inverters fully comply with the DRM requirements in AS/NZS 4777
.2:2015. The pin definition is showing below. For details on the working logic, please refer
to the standard document of AS/NZS 4777.2:2020. The DRM controlling device is not in
the scope of supply of Solis.
Some European countries may require a simply logic interface relay or contactor switch to
operate the RUN/STOP of inverters. For Solis European version inverters, the Pin 13 and
Pin 14 can be used to perform the control logic (Not available in South Africa).
The logic interface relay or contactor switch is not in the scope of supply of Solis.
When the relay is closed (Short between Pin13 and Pin14), the inverter can operate normally.
When the relay is opened (Open between Pin13 and Pin14), the inverter will reduce its output
power to zero within 5s.
After wiring connection of DRM or Logic interface, please refer to section 7.5.8.1 to enable
the DRM/Logic interface function..

4.3 Meter Connection

The inverter can work with a three phase smart meter to achieve Export Power Management
function and/or 24hour consumption monitoring function.
The Pin 1 and Pin 2 of the 16-Pin COM port are used for Meter RS485 communication.
