Explanation DRM Port
(For remote shutdown function)
Understanding the DRM Function
In photovoltaic inverters, DRM stands for Demand Response Management. Solis inverters include a remote shutdown feature, enabling the inverter to be powered on or off remotely using logic signals.
The DRM port is equipped with an RJ45 terminal, where Pin 5 and Pin 6 are designated for the remote shutdown functionality.
Example RHI-(3-4.6)K-48ES-5G
Example S6-EH3P(12-20)K-H
Example S6-EH3P(5-10)K-H-EU
Advantages of DRM
- Enhancing grid stability: By adjusting power output according to grid requests, DRM-enabled inverters contribute to maintaining grid stability, especially during periods of high demand or unexpected fluctuations.
- Supporting renewable energy: DRM facilitates the integration of renewable energy into the grid by preventing overloading.
- Environmental impact: During peak demand periods, DRM can help reduce dependence on fossil fuels, lowering greenhouse gas emissions.
How DRM Works
Solis inverters support remote shutdown function to remotely control the inverter to power on and off through logic signals.
How to activate DRM
DRM default setting is “OFF”, if DRM set “ON”, but the logic interface un-connected to the switch or the switch is open, the inverter HMI will display “Limit by DRM” and the inverter output power will be limited to zero.
Via the Display (5th Generation):
Please note: The on-screen menu may vary depending on the HMI version installed on your inverter. If you are unable to locate the option, please contact your local After-Sales Support team for assistance.
Option 1:
- Navigate to “Advanced Settings”.
- Select Special Settings
- Chose “Work Mode Setting”
- Go to “DRM” and set it to “On”.
Option 2:
- Navigate to “Advanced Settings”.
- Select “STD. Mode Settings”.
- Choose “Initial Settings”.
- Go to “DRM” and set it to “On”.
Via direct Bluetooth connection (S6 Generation):
Create a direct connection to your inverter via Bluetooth. See https://solis-service.solisinverters.com/a/solutions/articles/44002504766?lang=en for details.
- Navigate to “Grid Code Settings” and select “Advanced Settings”
- Click on DRM Settings
- Move the toggle to activate the DRM port
Via SolisCloud:
- Log in to your SolisCloud account at https://www.soliscloud.com/ .
- Navigate to the Menu option, select "Device", and click on the serial number of your inverter.
- In the top right-hand corner, click on "Inverter Control".
- A pop-up window will appear. Carefully read the Disclaimer and agree to the Terms and Conditions to proceed. Note: If you do not agree to the terms and conditions, access to the inverter control will not be granted.
- For security reasons, another window will open. Enter your SolisCloud account password and click "OK".
- This will direct you to the inverter control landing page. In the menu on the left side, click on "Grid Code Settings".
- In the sub-menu, select "DRM Setting".
- Here, you can enable the DRM port. Once enabled, ensure you click "Save" to apply the changes.

Key Considerations
- DRM participation may be optional or required, depending on local regulations and your utility provider.
- Enrolling in DRM programs could impact your solar energy production and self-consumption patterns.
