# SunSpec (generic)

> Generic SunSpec Modbus integration within our EMS

Source: https://voltmasters.io/en/docs/device-integrations/pv-inverters/sunspec/

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

> **Note**
>
> 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.
