• Full compliance with the regulations on protection and grid connection (synonymous with safety)
  • Possibility to use the products with any type of photovoltaic panel (versatility of use)
  • Supervision of the design and production processes in accordance with ISO 9001 standards (certainty of product robustness and reliability)
  • High conversion efficiency (for certain and on-going profitability)
  • Customizable Megastation turnkey solutions with integrated MV transformer

Advanced Modularity exists at inverter & component level

  • High redundancy and protection against energy loss
  • Long product life –
    • Electronic components work at lower temperature
    • Modules switch on and off in a balanced way, with a full electronic control, until the machine reaches its maximum power

High availability from Independent power modules due to service simplicity

  • Defective power modules can be easily replaced without stopping the functioning of the inverter
  • Semi skilled labor on site can replace power module

Higher energy yield due to unique inverter architecture

  • Higher generation due to wider MPPT window, leading to longer working time for inverter (early start and late sleep)
  • Inverter operates in higher efficiency zone for longer period of time as compared to other inverters
  • Lower auxiliary losses (Fan runs only when module is operational)
