Maximum Yields - Stable Utility Grids

The Power Plant Controller guarantees PV system operators maximum yields and contributes to the stability of public utility grids. It meets the requirements of grid operators worldwide with its ability to regulate voltage, reactive and active power and the power factor at the grid feed-in point quickly and precisely.

The SMA Power Plant Controller allows large-scale PV power plants to meet all needs of modern competitive PV power plants.

Higher Yields for PV System Operators

Quick and precise regulation guarantees PV system operators optimized yields. Downtime can be reduced and smooth plant operation guaranteed. Remote configuration and monitoring reduce maintenance costs in the module array.

Higher Stability for Grid Operators

The Power Plant Controller makes your PV farm's behavior a calculable variable in the utility grid. It meets all grid control requirements, guaranteeing grid stability at all times. The advantage: reliable integration of large PV power plants into public utility grids.

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.



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.

Active power reserve

Active power reserve
Automatic active power increase with a set power underfrequency along a predefined characteristic curve.

Control of Compensation facilities (STATCOM)

Control of Compensation facilities
Capacity banks and static reactive power compensators (STATCOM) can be integrated into plant control.



SMA inverters like the new SUNNY CENTRAL 2200 / 2500-EV expand the functionality of the Power Plant Controller for grid stability.


Q at Night

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

Dynamic grid support

Dynamic grid support

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