The complex, highly customized PV installation covers four individual sites, each divided into multiple sub-sites, and a mix of rooftop, ground, and carport installations.

Plano, Texas, October 21, 2013 - AEG Power Solutions (AEG PS), a global

provider of power electronics for renewable energies, and its subsidiary
skytron energy, a global leader in monitoring and control solutions for
utility-scale renewable energy power plants, today announced the successful
deployment of a 5.8 MWp commercial PV installation for PPA Partners in Yuma,
Arizona.

The complex, highly customized PV installation covers four individual sites,
each divided into multiple sub-sites, and a mix of rooftop, ground, and
carport installations.

AEG PS supplied solar inverters from its broad range of modular and central
inverter products to optimally cover the different sites. The solution
included Protect PV.500 inverters, which feature power stacks with advanced
measuring and control technology to enable DC input voltages of up to 1000
VDC. It also included MPV.Systems, whose transformer-less modular design
allows up to five inverter modules to be turned on as needed to match the
solar power available, and therefore to run at optimal efficiency. This
optimization, with advanced inverter design and no transformer losses,
yields efficiencies of up to 98%.

skytron energy provided a complete monitoring, control and supervision
package which includes the PVGuard control room platform. The PVGuard
software integrates all sites into one intuitive visualization platform. The
installed instrumentation and control system incorporates intelligent string
combiner boxes, data loggers, weather and irradiation sensors, and a central
power plant controller. All functions of a complex power generation plant
are covered: real-time condition monitoring and data acquisition, long-term
data storage, and grid stability management. The skycontrol power plant
controller ensures automatic control of grid injection and provides newly
developed remote interfaces for manual setpoint inputs. These enable the end
user to remotely control active and reactive power, ramp rates, and power
curtailment.

PPA Partners is a national renewable energy project development company with
over 50 MW of projects currently under development. "Delivering this highly
complex installation from the design to the final grid connection has been a
fantastic collaborative effort," says Bruce Mercy, CEO of PPA Partners.

"The joint AEG Power Solutions and skytron energy team supported us in
planning the architecture of the entire PV power plant, in choosing the best
components and in designing an optimum plant operation," continues Mercy.
"The comprehensive service and support from a very competent team has been a
great experience."

"AEG PS and skytron energy are joining forces to meet the demand of their
growing North American customer base. North American customers are served
by local experts in the companies' joint sales and service center in Plano,
Texas, which is focusing on commissioning, operations, maintenance, service,
and sales support," comments Enrique de La Cruz, President Americas of AEG
Power Solutions. "Our combined expertise allows us to propose complete
solutions and services for resilient, efficient solar installations but also
for complex micro-grids."
