Power Plant Controller

Power Plant Controller

Feed-in management made easy

With its fast and direct control, the SMA Power Plant Controller guarantees the maintenace of setpoints for responding to requirements from the PV power plant and the utility grid to both plant- and grid operators. It controls PV power plants in accordance with the requirements of the grid operator and, through the adaption of active- and reactive power, contributes to the stabilization of the utility grid. Thanks to the fast implementation of control commands, it ensures the highest possible system availability at all times.

Flexible park control for all PV power plants

The SMA Power Plant Controller offers intelligent and flexible solutions for the park control of all PV power plants in the megawatt range. It is suitable for PV power plants with central inverters as well as for those with decentralized string inverters. With simulation tools valuable predictions on the behaviour of the Power Plant Controller and the design of the plant are already possible before the commissioning of a PV power plant.

The parametrization and configuration of the Power Plant Controller can be performed with ease via remote access. With easy expandability for new communication protocols, standards for individual connections and a modular design, the Power Plant Controller is well suited to meet the future requirements of PV power plants.

Extremely quick response times

The SMA Power Plant Controller manages all parametres which are necessary for a constant stability of the grids.

On demand

On demand
New target values for reactive power or the power factor are implemented in a matter of seconds.


Predefined values for reactive power or the power factor are recieved and then implemented on time.

Constant reactive power or a power factor are made available on a permanent basis or by request.


Dynamically specified values for reactive power or powqer factor are managed at the grid connection point.

Ramp Rate Control

Ramp Rate Control
The increase rate of active power is limited.

Continuous Curtailment

Continuous Curtailment
There is a seamless reduction of active power.

Active power control

Active power control
Automatic reduction of active power at a defined grid frequency according to a definable characteristic curve.

Sunny Central CP-XT


SMA inverters like the new Sunny Central CP-XT accomplish the functions of the Power Plant Controller.


Q at Night
PV plants can also provide reactive power at night. Constant or dynamic values are preset.

Dynamische Netzstützung

Dynamic grid support
The inverter stays connected to the grid during voltage drops and supports the grid by feeding reactive power.
