Solar PV Application Categories

  • Offline solar PV system
  • Grid-connected solar PV systems
     - High power solar PV (>100 kW)
     - Medium power solar PV (1 kW ~ 10 kW)
     - Micro-inverter (200 W ~ 300 W)

Main Challenges and System Considerations

  • Higher reliability and lower assembly/manufacturing costs
  • Relatively harsh environment with temperatures of up to +125°C
  • Power conversion efficiency is critical and need components that consume as little power as possible
  • Keeping the generated harmonics below the regulatory levels
  • Maintain low dc injection current levels onto the grid Why Choose ADI?
  • ADI’s expertise in integrated energy measurement—300 million ADI metrology-based meters deployed
  • 50% of all electrical grid equipment worldwide uses ADI converters
  • Precision measurement of current & voltage through highly accurate converters and amplifiers
