Power-One Inc. (Camarillo, California, U.S.) unveiled four new inverters at the Intersolar Europe trade show in Munich, including a microinverter and an inverter with a power output of up to 1.4 MW.

On June 7th, 2011, Power-One Inc. (Camarillo, California, U.S.) unveiled four new inverters at the Intersolar Europe trade show in Munich, including a microinverter and an inverter with a power output of up to 1.4 MW.

The new inverters include the Aurora Ultra-1400 central inverter, the company's largest inverter for renewable energy applications, the Aurora Micro-0.3 micro-inverter, the Aurora Uno-2.0 and 2.5 single-phase inverters and the Aurora Trio-27.6 and 20.9 three-phase string inverters.

"The new offerings expand our broad array of products and services for the solar market," said Power-One President of Renewable Energy Solutions Dr. Alex Levran.

"We are excited to present not only several new inverters which combine high innovation content and key features, but also to introduce the AURORA Vision offering which provides greater system control and yield for our customers."



Power-One joins the microinverter movement

Microinverter companies have attempted to position their products as a disruptive technology to conventional string inverters.

As such, the introduction of a microinverter line by the second-largest maker of inverters for solar photovoltaic (PV) applications is an interesting signal for the future of the technology.

In presenting the Micro-0.3, Power-One cites the advantages typically advertised by microinverter makers, including minimizing losses in challenging conditions and module-level MPPT management.



Ultra-1400 offers high conversion efficiencies, wide input voltage range

Power-One states that its large-scale Ultra-1400 offers power conversion efficiencies up to 98.7%. The inverter also accepts an extra wide input voltage range and multiple maximum power point tracking (MPPT) channels, which the company says allows it to optimize energy harvest across a wide array of operating conditions.

The inverter's enclosure includes passive liquid cooling and total segregation of internal compartments. Power-One notes that the inverter's modular structure allows for extraction of sub-assemblies, which it says eases both installation and maintenance.



Aurora Vision offers a range of monitoring and control services

The company also unveiled its new Aurora Vision line at the trade show, which involves hardware, software and accessories.

The company states that in order to maximize system energy output while minimizing costs, the software includes a full range of system fault management, diagnostics, asset tracking, performance index and alerting services.

Accessories include a desktop monitoring system and the EVO Easy control, which allows monitoring of inverter performance over the internet.
