Flexibility in power plant design

  • The photovoltaic power plant can be built for extremely demanding conditions, whether they involve heat, cold, high altitude and/or highly corrosive areas.
  • ACE 300 is compatible with all module types, including bifacial and the latest high-power modules.
  • A large number of inputs enables various plant design configurations and does not limit options.
  • ACE 300 is designed for hybrid solutions including both solar PV and energy storage.

Reliability and efficiency

  • The ACE 300 design is based on reliable, proven technology with a new innovative approach to guarantee reliability.
  • The structure is simple and innovative; a smaller number of components requires less maintenance and maximizes reliability, especially in challenging conditions.
  • Due to the two-part structure, maintenance and transport is cost-effective.
  • Excellent DC to AC conversion efficiency.

Low investment and maintenance costs

  • ACE 300 can be connected to up to one thousand modules, which reduces the number of inverters in the solar power plant and saves costs.
  • The PV strings can be connected directly to the inverter without combiner boxes, saving costs.
  • The ACE 300 inverter is designed to be reliable and durable, taking into account the estimated 25 years’ lifetime of the PV plant.
