Central Inverters

SUNNY CENTRAL- High Tech for solar power stations

We have developed the Sunny Centrals specially for use in large PV power stations and open-field plants. Hence they possess completely special properties. String monitoring, capacity for teamwork and the ability to feed into the medium-voltage power grid make them first choice for PV systems with homogenous structure.

The Sunny Centrals are easy to install - indoors as well as outdoors. With peak efficiencies of over 98 % they belong to the most efficient central inverters on the market. maximum reliability and durability furthermore ensures the greatest investment security.

High performance on the scale of power stations

High flexibility in plant design and minimal systems costs with even more power: the proven High Efficiency series for direct connection to the medium-voltage transformer has once again been improved and complies with the complex demands of PV plants on the scale of power stations. This means that maximum power in continuous operation has been increased by ten percent compared to the nominal power for as long as the ambient temperature does not exceed 25 °C. At the same time, the devices offers comprehensive grid management functions - including immediate reconnection after a grid voltage drop. The device class can be simply expandable and connected via several communication interfaces.
