At the events exhibition, the company will also showcase its latest AURORA PV inverter products in hall 3.1 booth C9, including the redesigned AURORA MICRO micro-inverters and the new AURORA CDD monitoring device for micro-inverters and power optimizers.
In addition, visitors will have the opportunity to learn more about Power-Ones broad portfolio for residential and commercial PV installations featuring the AURORA OPTI power optimizer, the AURORA UNO single phase inverter, the AURORA TRIO three-phase string inverters as well as several monitoring solutions. The 27th EU PVSEC, the worlds leading science-to-science, business-to-business and science-to-industry forum for the global PV Solar sector, takes place in Frankfurt, Germany from September 24 to 28, 2012.
At the conference, Power-One will present a new inverter with VSI (voltage source inverter) topology which extends the operating mode of the device from day-time to full-time. The new concept allows absorbing or injecting reactive power into the grid, thereby improving the power quality, the voltage stabilization, and reactive power compensation. Power-Ones presentation PV Inverter Extended Grid Services From Day-Time to Full-Time Operation will take place on Wednesday, September 26, 2012, at 5:00 p.m.
Extending the grid-support services of inverters for utility-grade installations is one of the key factors to ensure long-term sustainability without requiring large investments on system infrastructure, said Paolo Casini, Vice President, Product Marketing at Power-One. The ability of the inverter to support the grid on a full-time basis will become increasingly important in the future. This is why we developed a new topology, which also allows generating reactive currents during times when the primary source is not available for example at night.
AURORA MICRO-0.25 and AURORA MICRO-0.3
Power-Ones new AURORA MICRO-0.25-I and AURORA MICRO-0.3-I micro-inverters offer several improvements compared to the earlier product version, including increased efficiency ratings of up to 96.5 percent, which is one of the best in this class. A broader input voltage range and an extended MPP DC voltage range allow installers to deploy the AURORA MICRO devices with PV modules of different make and performance, thereby giving them greater design flexibility. 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-Ones micro-inverters can be linked to the internet with the AURORA CDD.
AURORA CDD
Specifically designed for the use with Power-Ones AURORA MICRO micro-inverters and AURORA OPTI power optimizers, the new monitoring device AURORA CDD connects them to the internet in a simple and quick way. Without requiring any additional wiring, the AURORA CDD allows the monitoring of up to 30 module inverters or power optimizers using wireless communication technology. Via Power-Ones web-based monitoring portal, plant operators and installers can control the performance of their PV system in real-time and detect failures rapidly.
