Solar Power UK: Power-One to present micro-inverters and utility-scale inverters for the UK market

Popular Articles

Solar Power UK, Birmingham – September 27, 2012 – Power-One, Inc. (Nasdaq:PWER), a leading provider of renewable energy and energy-efficient power conversion and power management solutions, will present both its largest and its smallest PV inverters at Solar Power UK: the AURORA ULTRA central inverter system with an output of up to 1.5 MW and the improved AURORA MICRO module inverter with an output of 250 W and 300 W. Solar Power UK is one of the leading solar platforms in the UK, bringing together the entire PV industry. It takes place in Birmingham from October 2 to 4, 2012.

Inverter solutions for small residential applications as well as large utility-scale solar parks will not only be the highlight at Power-One’s booth B40, but will also be subject of two presentations the company will be hosting at the accompanying conference. At the “Practical Large Scale PV” area, of which Power-One is one of the sponsors, it will demonstrate how the energy harvesting in large-scale solar installations can be maximised with the right inverter solution. The company’s presentation “Inverters for large scale – products and possibilities” will take place on Thursday, October 4 at 10:40 a.m.

Power-One’s second presentation “Inverters for domestic roofs – micro-inverters versus string inverters” will address PV inverter solutions for the residential sector. On Wednesday, October 3 at 4:20 p.m., the company will compare the advantages and disadvantages of both solutions and will give plant designers and installers practical advice on how to choose the perfect inverter for their specific needs.

“Due to the new feed-in tariff regulations, the UK solar market has experienced some major challenges in the last months. However, the changes also opened up new market segments. For example, the large-scale PV sector with up to and over 5MW is reviving as a consequence of the declining PV component prices and the new Renewable Obligation,” said David Lowen, Director of Sales for Western Europe Renewable Energy at Power-One.

“Moreover, the market for micro-inverters and power optimizers also offers great potential in the UK. According to a recent study by IMS Research, the UK will on the one hand continue to support a healthy residential and small commercial sector. On the other hand, the analysts expect module inverter solutions, which are ideally suited for small residential installations, to amount for one fourth of the total market share by 2016.”


With an output of up to 1.5MW, Power-One’s ULTRA-1400 is the largest solar power inverter currently available in the Power-One AURORA product range. Designed with the specific needs of large utility-grade installations in mind, this liquid-cooled, high-powered inverter offers industry-leading power conversion efficiencies of up to 98.7 percent over a wide input voltage range. Four high-speed MPPT channels optimize energy harvesting across a wide array of operating conditions.

An IP65 enclosure, which protects the active parts of the unit in a watertight and pollution-free chamber, further improves the system long-term reliability, extends the maintenance cycle and reduces the costs of maintenance. Moreover, this very large system also significantly reduces the wiring requirements and on-site testing thanks to separated and dedicated compartments for DC and AC.


Power-One’s improved AURORA MICRO-0.25-I and AURORA MICRO-0.3-I micro-inverters offer several advantages, including increased efficiency ratings of up to 96.5 percent, which is one of the best in this class. Furthermore, a broader input voltage range and an extended MPP DC voltage range give installers more design flexibility, since the AURORA MICRO devices can be deployed with PV modules of different make and performance. Thanks to a robust IP65 enclosure, an HF isolation and electrolyte-free capacitors, the product is ideally suited for unrestricted use under any environmental conditions and benefits from an increased product lifetime and long term reliability.

By minimizing efficiency losses from partial or temporary shading, panel mismatching or module aging, the AURORA MICRO module inverters offer an alternative to traditional string inverters. In addition, micro-inverters ensure system expandability at panel level, allow for easy plant monitoring and reduce the susceptibility to fault. Power-One’s micro-inverters can be linked to the internet with the AURORA CDD.
