SunSpec (generic)

Generic SunSpec Modbus integration within our EMS

Our EMS supports a generic SunSpec integration for PV inverters. SunSpec is an open communication standard, maintained by the SunSpec Alliance, that defines a common Modbus register layout for solar inverters and related equipment.

Because the SunSpec model is implemented by many manufacturers, this integration allows our EMS to connect to many SunSpec-compliant PV inverters without a brand-specific adapter.

Supported devices

• Generic SunSpec inverter: any PV inverter that exposes a standard SunSpec Modbus interface

When a dedicated brand integration is available (for example SMA, Huawei, ABB, Sungrow, Growatt, or Solis), use that integration. The generic SunSpec option is intended for inverters that are SunSpec-compliant but do not yet have a dedicated brand integration.

Compatible brands

Many SunSpec-compliant manufacturers can be added directly by selecting the brand in the add-device wizard; they connect through this same generic SunSpec integration, without a brand-specific adapter:

• Afore

• Aiswei

• Altenergy Power

• Canadian Solar

• Danfoss Solar

• Delta Electronics

• Deye

• Eltek

• GoodWe (PV inverters)

• Hoymiles

• Ideal Power

• Kaco

• Outback Power

• Q Cells

• Schneider (PV inverters)

• Sofar

• Solectria

• Yaskawa Solectria

If your inverter is not in this list but exposes a standard SunSpec Modbus interface, use the Generic SunSpec inverter option.

EMS functionality

With the current integration, our EMS enables:

• Monitoring of PV production data

• Control functionality where supported by the inverter (for example active power curtailment)

• Integration of PV production into broader energy management strategies

Additional functionality may be added over time as integration capabilities evolve.
