Power One Aurora, 300 Watt, 208/240 VAC Microinverter

Power One Aurora, 300 Watt, 208/240 VAC Microinverter

The new Aurora 250 & 300-watt micro-inverter product offers something new to Power-One customers. The ability to individually link all modules within a specific installation is an alternative to the traditional Aurora string inverters Power-One is famous for.

Micro-inverters have some advantages over string inverters. They allow you to control the panels output individually and offer Maximum Power Point Tracking (MPPT) for each single module.

They also allow you to control individual panels in different ways and reduce the losses in efficiency in a variety of challenging conditions.


  • ‘Electrolyte-free’ power converter to further increase the life expectancy and long term reliability
  • Outdoor enclosure for unrestricted use under any environmental conditions
  • Increased energy harvesting thanks to the MPPT algorithm which works at the level of each solar panel in any light condition
  • Enhanced MPPT control with reduced DC input current ripple
  • HF isolation to fits any application that requires the positive grounding of DC input terminals
  • 96.5% maximum efficiency
  • Ease of installation by the implementation of a package inclusive of proprietary wireless communication hub
  • Reduced susceptibility to fault. In case of a component failure only the energy produced from one PV module will be lost

Aurora Micro Inverter System Installation

  • The AURORA MICRO Inverter offers ease of installation with an AC trunk and drop cable configuration
  • The mounting bracket on the AURORA MICRO inverter ensures simple and durable mounting on commercially available racking solutions
  • AC Cabling compatible with 60, 72 and 96 cell modules in both portrait and landscape orientation
  • Locking connectors and weatherproof accessories ensure long term reliable operation of the plant

Aurora Vision Monitoring

  • Easy monitoring solution for homeowners with AURORA Easy View
  • Complete reporting, analytics and diagnostic view for installers with complete control of installation process and access security
  • Tightly integrated micro-inverter and monitoring solution
