Micro Inverters

Converts PV power to single phase power to directly feed the AC loads or can be grid tied with advanced synchronization techniques


  • Optimizing energy harvest from panel by executing real-time MPPT algorithm
  • Max. MPPT Efficiency 96%
  • Anti-Islanding/ Islanding modes
  • Add on to existing UPS system with a power selector switch
  • Fitted back to panel with an easy fitment & arrangement mechanism
  • Can parallel any number of panel micro-converter outputs
  • Grid synchronized when connected to the grid
  • Optional  Communication interface using RS-485

Applications - Micro-inverter Grid Tie Application

  • Single or multiple micro-inverters can be tied to the grid
  • The micro-inverter can directly supply to the AC load avoiding the use of battery
  • On grid power failure the micro inverter can be programmed to work in anti-islanding mode
  • The micro-inverter synchronizes to the grid frequency
  • Each inverter provides around 240 Wp power
  • Providing multiple micro-inverters can enhance power harvesting and also improve reliability of the system
