Power-One showcases its PV solutions for residential usage at Ecobuild 2014

Power-One, a member of the ABB Group and the world’s second largest designer and manufacturer of photovoltaic inverters, has announced that the company will present its extensive portfolio of PV inverters and monitoring systems for landlords and home owners at Ecobuild in London.


From March 4 to 6, Power-One will show select PV inverters, such as the new three-phase TRIO-5.8/7.5./8.5-TL-OUTD and the well-known TRIO-20.0/27.6-TL-OUTD string inverters as well as the single-phase string inverters PVI-3.0/3.6/4.2-TL-OUTD and UNO-2.0/2.5-I-OUTD. Apart from this strings-inverter range, Power-One will also display its innovative AURORA MICRO-0.25-I and AURORA MICRO-0.3-I micro-inverters as well as its monitoring solutions for residential PV installations at booth S2120 (South Hall).


TRIO-5.8/7.5./8.5-TL-OUTD and TRIO-20.0/27.6-TL-OUTD

The TRIO-5.8/7.5./8.5-TL-OUTD are Power-One’s smallest transformerless string inverters. With an output of 5.8, 7.5, and 8.5kW respectively, the devices benefit from a redesigned topology used in other TRIO models. They ensure high conversion efficiencies of up to 98 percent across a wide input voltage range. Both, the TRIO-7.5 and the TRIO-8.5, feature two independent MPP trackers (MPPTs), offering maximum installation flexibility for optimal energy harvesting. Thanks to their robust IP65 enclosure, the three-phase string inverters are suitable for unrestricted outdoor use. A sliding front panel makes installation and maintenance quick and easy. Moreover, a graphic display allows for quick connection, parameter setting, and functional control.


The string inverters TRIO-27.6 and TRIO-20.0 are the ideal choice for large roof top applications on commercial or municipal buildings by contrast. With an output of 20.0kW and 27.6kW, two independent MPPTs, and an efficiency rating of up to 98.3 percent, the three-phase string inverters offer more flexibility and lower wiring cost to installers who have large installations with varying aspects or orientations than its smaller predecessors.


“With the TRIO-5.8/7.5./8.5 we have closed the gap within our residential product portfolio and ensure the availability of excellent, high performing inverter solutions from small residential to large commercial rooftop installations with an output range of 5.8kw to 27.6kW,” said David Lowen, Local Sales Manager for PG Solar, UK, at ABB.


PVI-3.0/3.6/4.2-TL-OUTD and UNO-2.0/2.5-I-OUTD


Complementing the typical number of rooftop solar panels, Power-One’s PVI-3.0/3.6/4.2-TL-OUTD single-phase string inverters are ideally suited for average size family homes: these rugged outdoor inverters have been designed as completely sealed units to withstand the harshest environmental conditions as well as to provide home owners with an energy efficiency rate of up to 96.8 percent due to two independent MPP trackers.


Developed for the average-sized rooftop installation, the UNO-2.0-I and UNO-2.5-I are Power-One’s latest and smallest single-phase string inverters. Both units benefit from the company’s proven high performance technology. The series offers some differentiating features, including a special built-in heat sink compartment, a front panel display system, and an efficiency rating of up to 96.3 percent.


Their wide input voltage range also qualifies the PVI-3.0/3.6/4.2-TL-OUTD as well as the UNO-2.0/2.5-I-OUTD for low power installations with reduced string size.




The AURORA MICRO-0.25-I and AURORA MICRO-0.3-I micro-inverters are especially suited for small, residential installations as they minimize efficiency losses from partial or temporary shading, panel mismatching or module differential ageing. With an output of 300W and 250W respectively, these products offer a broad DC input voltage range, an extended MPP DC voltage range as well as best-in-class efficiency ratings of up to 96.5 percent. Moreover, a rugged outdoor enclosure, a HF isolation and electrolyte-free capacitors allow for unrestricted use under any environmental conditions and further increase the product lifetime and long term reliability.



Power-One’s monitoring device has been specifically designed for the use with the company’s MICRO micro-inverters: CDD connects them to the internet in a simple and quick way. Without any additional wiring, the monitoring solution allows the monitoring of up to 30 module inverters or power optimizers using wireless communication technology. Via Power-One’s web-based monitoring portal, plant operators and installers can control the performance of their PV system in real-time and detect failures rapidly.
