Power-One, Inc. has launched its new AURORA UNO-2.0-I-W and UNO-2.5-I-W single phase string inverters and its new AURORA 25kW-WIND-INTERFACE for small wind applications.

With the AURORA UNO-2.0-I-W and UNO-2.5-I-W single phase string inverters for wind applications, Power-One offers a new look inverter for small residential wind turbines. Designed with the demands of urban property owners in mind, the new devices have an output of up to 2kW or 2.5kW making them the right choice for small wind applications. the redesigned AURORA UNO inverters offer new features, such as a special built-in heat sink compartment and a front panel user interface. Moreover, the AURORA UNO-2.0-I-W and UNO-2.5-I-W feature an efficiency of up to 96.3 percent. A granular, 16 point power curve customization optimizes the energy production for each wind turbine. Designed as a completely sealed unit, the device even withstands the harshest environmental conditions. Both wind inverters are compatible with the AURORA 4000 and 7200 as well as with the 15kW and 25kW Wind Interfaces from Power-One. With the AURORA 25kW-WIND-INTERFACE, Power-One offers more flexibility for small wind applications. The 25kW wind interface is designed to be a smart rectifier: once programmed with the turbine’s power curve, it controls the output of single or multiple inverters allowing scalability for installation. Additionally, the wind interface box offers efficiencies of up to 99.6 percent, provides over-voltage protection and drives both a diversion load and a dumpload braking system.
