# SunSpec (Generic)

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

{% hint style="info" %}
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.
{% endhint %}

### 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.
