Maximum flexibility and reliability.

The Central Power String Solution (CPSS) is a system solution combining the advantages of centralised and decentralised plant configurations.

The string collector transports the direct current from the solar modules to the respective string inverter via a DC line. All string inverters are mounted on a rack (optional) with a protective cover in a central position in the solar park. AC wiring is only required from there to the adjacent container with transformer, switch-gear and low-voltage distribution. Alternative the Inverter can be mounted directly under the solar modules near the CPSS container.

The CPSS is shipped in five standard sizes for PV systems with 0.6 MVA, 0.8 MVA, 1.0 MVA, 2.0 MVA and 2.5 MVA.

The turnkey system consists of:
