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 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.

The CPSS consists of the following components:

  • blueplanet 50.0 TL3 inverters
  • Inverter mounting rack
  • blueplanet Mini-Argus 50.0 DC combiner boxes
  • Pre-assembled 12 or 20 ft container with low-voltage AC distribution board, medium voltage transformer, switch-gear

Available system sizes of the CPSS with blueplanet 50.0 TL3 inverters: 0.6 MVA / 0.8 MVA / 1.0 MVA / 2.0 MVA / 2.5 MVA.

Coming soon: the CPSS 3.0 and 6.0 including the blueplanet 125 TL3 inverter with 1,500 V input voltage.


  • Flexible design
  • Multiple MPP trackers available
  • String monitoring solution not required due to use of string inverters
  • Easier, faster and cheaper service possible
  • Much lower downtime losses and hence faster return on investment
  • Compatible with all available monitoring and park control systems
