MIG300 Microinverter

Model Number: MIG300
Darfon believes in creating solar power solutions that are efficient, dependable, and user friendly. With that in mind, the MIG300 microinverter was designed to be easy to handle and install. It has a nominal input power rating of 300W with a voltage range compatible with all conventional 60 and 72 cell modules.
Improved Safety
  • Eliminates the need for high voltage DC wiring
Flexible PV Array Design
  • Integrated grounding eliminates the need for additional GEC
  • Up to 15 units on a 20A breaker and 23 units on a 30A breaker
  • Scalable for future expansion
Maximized Energy Production
  • Debris/shading does not impact energy production for the entire PV array
  • Cloud-based monitoring through web browsers and mobile apps
  • Fully potted design for better heat dissipation
