At its booth in the foyer east, Power-One will present the new transformerless AURORA PVI-8.0-TL and AURORA PVI-6.0-TL three-phase string inverters for residential applications to the German public for the first time. Furthermore, visitors will have the opportunity to learn more about Power-Ones innovative AURORA MICRO inverters as well as its broad portfolio of PV inverter products and monitoring solutions, including the single-phase AURORA UNO inverters and the three-phase AURORA TRIO inverters.
At the Symposium Photovoltaische Solarenergie, the German PV industry meets to discuss the future of renewable energy generation, says Gerhard Schackert, Sales Director Northern EMEA at Power-One. This is why we have chosen this event to present our latest PV inverter innovations to the public.
AURORA PVI-8.0-TL and AURORA PVI-6.0-TL
With an output of 8kW and 6kW respectively, the AURORA PVI-8.0-TL and AURORA PVI-6.0-TL are the smallest transformerless three-phase string inverters Power-One has ever offered. Both models benefit from the cutting-edge technology perfected in the AURORA PVI-10.0/12.5 inverters and are ideally suited for single-family or semi-detached houses.
Thanks to two independent MPP trackers, systems can be designed with two separate strings with different orientations. This allows for an optimal energy yield from installations with two different roof pitches. Moreover, a wide input voltage range and high efficiency values of up to 97.6 percent permit deploying the two inverter models in different installation conditions. This does not only ensure a maximum energy harvesting, but also guarantees the high reliability and flexibility that distinguishes Power-Ones AURORA inverters.
AURORA MICRO-0.25-I and AURORA MICRO-0.3-I
Both the AURORA MICRO-0.25-I and AURORA MICRO-0.3-I micro-inverters offer efficiency values of up to 96.5 percent, which are amongst the best in their class. Their broad DC input voltage range with a maximum of 60V DC and the improved MPPTs allow installers to use these micro-inverters with a number of different manufacturers modules as well as a range of various outputs. By offering greater design flexibility, the micro-inverters guarantee maximum energy harvest on roofs with different pitches and orientations.
Minimizing efficiency losses by partial or temporary shading, panel mismatching or differential module aging, the AURORA MICRO inverters offer a valuable alternative to traditional string inverters. Moreover, the micro-inverters allow expanding existing PV installations at panel level. This not only reduces the susceptibility to fault, but also simplifies plant monitoring. All of Power-Ones micro-inverters can be connected to the internet with the AURORA CDD monitoring device. Specifically designed for the use with Power-Ones AURORA MICRO inverters, the device can monitor up to 30 Power-One inverters thanks to its integrated wireless technology.
