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.

 

Sunny Central 800MV / 1000MV / 1250MV

for direct medium-voltage feed-in


High-performance medium-voltage station

For even more power, two Sunny Central HE inverters can be combined in a medium-voltage (MV) station, which feeds directly into a shared medium-voltage transformer. For example, two Sunny Central 630HE inverters can be combined into one Sunny Central 1250MV station. By removing the need for low-voltage transformers and using an amorphous transformer, efficiency is increased and, at the same time, inverter costs are lowered. The Sunny Central MV makes an investment that will continue to pay off in future.


 

Efficient

  • Greater efficiency without low-voltage transformers due to direct connection to the medium-voltage grid


Turnkey delivery

  • Complete with medium-voltage transformer and concrete substation for outdoor installation


Optional

  • Medium-voltage switchgear systems for a flexible structure in designing large PV farms
  • AC transfer station with measurement
  • Medium-voltage transformers for other line voltages (deviating from 20 kV)
  • Amorphous transformer for minimum open circuit losses
