Power One Aurora Micro 320 Watt 230 VAC Micro Inverter
Micro Inverter
International Model
Manufacturer Part Number: MICRO-0.3-I-OUTD
The new Aurora 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.
Features
- ‘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
- No DC input current ripple
- The HF isolation allows it to fit any application that requires the grounding of either one of the input terminations
- 95.5% of efficiency
- Ease of installation by the implementation of a package inclusive of proprietary wireless communication hub and grid interface
- Reduced susceptibility to fault. In case of a component failure only the energy produced from one PV module will be lost
- Up to 10 micro inverters directly connectable in a string

Detailed Description
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.
