Dyness Inverters

important

Currently, the integration is support upto a state of charge limit to 95%. This is because when the state of charge goes beyond 95%, the battery can stop listening to setpoints due to the actions of the battery management system. We are working on resolving this issue with Dyness and other partners.

Wiring

The SmartgridOne Controller and the Dyness inverters communicate via RS485 or Ethernet.

Ethernet

For correct ethernet wiring: Follow the the guidelines for ethernet wiring.

RS485

RS485 Wiring

• For correct RS485 wiring: Follow the guidelines for RS485 wiring.
• If the wiring shown in the table below is incorrect, please let us know.
• There is no general consensus in the industry about the usage of A and B for the RS485 polarity, so it may be counterintuitive and opposite of what you might expect for some devices.

Configuration

DH100F

The Dyness DH100F needs to be set to remote mode:

1. Click the main menu icon on the upper right corner of the main interface
2. Click "Data" in the main menu bar
3. Click "EMS" in the sub-menu bar
4. Click "RunSet" at the upper left of the navigation bar
5. Set the Control Mode to "Remote"

NOTE: RS485 Device Addresses

• You MUST give each device on the RS485 bus a unique address. Check the manual of the device on how to do this.
• Use lower addresses first (1, 2, ...) because the SmartgridOne Controller will find them faster!
• For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The SmartgridOne Controller will scan on those first.
