Power-One has launched the second generation of its micro-inverters, the improved AURORA MICRO-0.3-I and AURORA MICRO-0.25-I. The new version version is claimed to offer a broader DC input voltage range with a maximum of 65Vdc, an extended MPP DC voltage range and an enhanced MPPT control with reduced DC input current ripple. Moreover, the new units are said to reach best-in-class efficiency ratings of up to 96.5%. Power-One is showcased the products at Intersolar Europe.

Problem

One of the main benefits of equipping each module with its own micro-inverter is that each panel benefits from a separate MPPT, which creates the optimum power curve for any light conditions. This does not only minimize efficiency losses from partial or temporary shading, but also from panel mismatching. Moreover, the units ensure system expandability at panel level without the hassle of string re-sizing or panel matching.

Solution

The AURORA MICRO-0.3-I and AURORA MICRO-0.25-I micro-inverters have broader DC input voltage range with a maximum of 65Vdc, an extended MPP DC voltage range with an enhanced MPPT control supporting a reduction the the DC input current ripple. As the devices are directly connected to each individual solar panel, there is no need for string sizing nor to stand to any constraint in terms of topology and orientation of the PV modules not to mention the reduction of the effect of module aging. Moreover, Power-One’s AURORA MICRO micro-inverters offer many benefits to small rooftop installations including the speed and ease of installation, increased control of individual panels and maximized energy harvesting for every installation – regardless of its size.”

Applications

Residential PV installations.

Platform

The AURORA MICRO micro-inverters include a rugged outdoor enclosure and HF isolation allowing to fit any application which requires the grounding of either one of the DC input terminals. The units are electrolyte-free to further increase the product lifetime and long term reliability. As there are no high voltage DC BoS components, the installation of the micro-inverters is very easy. A proprietary wireless communication hub and grid interface which is included in the package further simplifies the set-up of the devices. To allow for easy and fast controlling of the energy harvest produced by a single module or the entire plant, Power-One’s micro-inverters can be linked to the internet with the AURORA CDD monitoring device.

Availability

June 2012 onwards.
