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.

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.
