Central inverter 134kW without LV/LV transformator.

New inverter system based on extractable modules of 67kW of power. Limited losses thanks to the output voltage increased to 380V. For a considerable reduction of the loss due to the mismatching phenomena, each module can be configured in multi-master for up to 6 independent MPPT, or in master slave with a single MPPT to improve the harvest of the energy in case of single failure. The inverter, without transformer, reaches 98% of peak efficiency. Inverter systems are delivered pre-configured and pre-tested, significantly reducing on-site wiring and testing operations.

Tecnical details:

  • New extractable module with increased power up to 67kW
  • Increased output voltage to 380V for limited losses
