Aurora String Combiners Parallel up to 20 PV Strings

Additional features include: 200 – 850VDC input range, fuse protection for both positive and negative connections, overvoltage protection with a replaceable varistor cartridge, IP65-rated enclosures, and a 0 to 95% relative-humidity operating range. Options include an integrated DC-output switch and analog inputs for up to four external sensors; such as irradiance, temperature, and wind speed.

These products support remote monitoring, via RS-485 communications, of a comprehensive range of critical operating parameters including: string currents, array voltage, fuse status, internal temperature, environmental sensor readings, and overvoltage protection status.

Aurora® String Combiners are ideally suited for use with Power-One’s Aurora® Commercial Inverters. Aurora® Inverters utilize high-efficiency power-conversion technologies, and high-speed independent Maximum Power Point Tracking (MPPT) channels, to increase the amount of usable power that is available from renewable-energy installations. This optimized energy harvesting can significantly increase the ROI of residential and commercial solar power plants.
