Tue, 10/14/2008 - 6:40am

Power-One AuroraSuiting Aurora commercial inverters, Power-One’s Aurora string combiners support paralleling and integrated current measurement for up to 20 photovoltaic strings. The devices exhibit an input voltage range from 200 VDC to 850 VDC, fuse protection for positive and negative connections, overvoltage protection with a replaceable varistor cartridge, and relative-humidity operating range between 0% and 95%. The combiners provide support for remote monitoring of string currents, array voltage, fuse status, internal temperature, environmental sensor readings, and overvoltage protection status via RS-485 communications. Options include an integrated DC-output switch and analog inputs for up to 4 external sensors, such as irradiance, temperature, and wind speed. The instruments come in an IP65-rated enclosure. Pricing is $3,000 each in 50 quantities.
