Power-One's AURORA ULTRA(TM) Series Increases Return on Investment for Utility Scale Power Plants
Power-One has focused on maximizing the ROI for PV utility plant owners from the product concept phase of the AURORA ULTRA(TM), through maximizing energy harvesting, lowering the total plant investment and minizing maintenance costs.
ORLANDO, Fla., Sept. 11, 2012-- SOLAR POWER INTERNATIONAL
energy and energy-efficient power conversion and power management solutions,
today announced their newest solution for large scale PV Plants, the
ULTRA-700/1100/1500-TL inverter series which is available in 780kW, 1.17MW
and 1.560MW models.
Power-One has focused on maximizing the ROI for PV utility plant owners from
the product concept phase of the AURORA ULTRA(TM), through maximizing energy
harvesting, lowering the total plant investment and minizing maintenance
costs. The AURORA ULTRA extends the power range of their inverters to 1.56
Megawatts and continues to provide the features AURORA customers have come
to expect. With a maximum of 98.6 percent efficiency and up to four
independent MPPT's, Power-One continues its leadership in energy harvesting.
In addition to high energy harvesting, the solar power generation loss in
the event of an inverter failure is reduced to 390kW, the power level of one
inverter building blocks. The inverter's modular design allows a 390kW block
to be field replaceable supporting up-time with a short mean time to repair.
The system level approach to lower initial investment of the entire plant
has resulted in innovations such as the 690Vac output voltage which enables
the use of high volume commonly available standard transformers and
protection equipment. The higher output voltage also results in decreased
cable costs offering further cost reductions.
Built with a NEMA 4X cabinet, the ULTRA is able to operate in harsh
environmental conditions. The AURORA ULTRA is available in pre-configured
turn-key solutions including the mounting pad and MV transformer under the
AURORA ULTRA STATION product line eliminating the cost of engineering.
"Power-One has looked beyond optimized inverter cost and developed inverter
features to maximize energy harvest and lower BOS costs for multi MW
projects", said Alex Levran, president of Power-One.
The AURORA maximum power point tracking (MPPT) algorithm ensures that the
inverter operates at the absolute maximum power point of the array.
The ULTRA inverter further improves the MWH plant output due to a maximum
inverter efficiency of 98.6%. In addition, the ULTRA's wide input voltage
range provides maximum energy harvesting over a wide module temperature and
The ULTRA 700/1100/1500 inverters host some of the most sophisticated
communication and grid management capabilities for utility monitoring and
interconnection requirements. These features can be configured based on
specific customer requirements. The ULTRA inverter series is a true utility
scale product in every sense. The inverter monitoring further incorporates a
Power-One intelligent string combiner option to provide array level
