Flexible Farm 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. Parameterization, configuration and plant diagnostics can be carried out directly on the Controller’s touchscreen or conveniently via the network. The modular design means that the Power Plant Controller can be individually adjusted in line with future needs and standards. Simulation tools allow valuable information on system behavior and plant design to be obtained as early as in the planning phase of a PV power plant (optional service).

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

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


Sunny Central CP-XT

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.

Dynamische Netzstützung

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