Ubiquiti`s cloud based sunMAX software provides monitoring capability for desktops and mobile devices.

The Microinverter provides multiple benefits including:
  • Maximizes power for individual solar panels
  • Eliminates high-voltage DC wiring for a safer solar installation
  • Lower installation cost
  • Higher overall system reliability
