The AURORA MICRO-0.3-I and AURORA MICRO-0.25-I. devices are directly connected to each individual solar panel, so there is no need for string sizing nor any topology or orientation constraints within the PV modules.
ORLANDO, Fla., Sept. 11, 2012-- SOLAR POWER INTERNATIONAL
energy and energy-efficient power conversion and power management solutions,
today announced the availability of its micro-inverters, the AURORA
MICRO-0.3-I and AURORA MICRO-0.25-I.
In keeping with Power-One's history of bringing innovation to the PV solar
inverter market to maximize energy harvesting and position as the pioneer of
the dual MPPT string inverter, the company has taken the next step to offer
panel level MPPT with the AURORA MICRO. This inverter system, which includes
the AURORA CDD communications device, expands the AURORA product portfolio
to cover applications with variation in module production. The best-in-class
efficiency rating of up to 96.5 percent and proprietary MPPT all combine to
bring the highest levels of energy production. The AURORA MICRO and the
complimentary AURORA CDD are now available in limited quantities to the US
Market and will ramp up to full availability in Q4 of 2012.
"How micro-inverters will be incorporated into the solar installations of
the future is currently one of the hot topics within the residential PV
industry," said Paolo Casini, vice president of product marketing at
Power-One. "It is our belief that micro-inverters will soon become a very
popular option for residential installers as the setup times will be reduced
without affecting the installation's energy harvesting capabilities. In
addition, micro-inverters also reduce the susceptibility to fault: in case
of a component failure only the energy produced from the affected PV module
will be lost."
The AURORA MICRO-0.3-I and AURORA MICRO-0.25-I. devices are directly
connected to each individual solar panel, so there is no need for string
sizing nor any topology or orientation constraints within the PV modules.
The micro-inverters also allow for a significant reduction of the effect of
module aging. 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.
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.
Additional features of 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. The AURORA CDD is the
proprietary wireless communication hub and grid interface provides the
homeowner an instantaneous view and historical view of the energy production
through the AURORA Integrated Web Server or via the internet through the
AURORA Easy View.
