Green inverters boast high conversion efficiency

Edited by the Electronicstalk editorial team Feb 28, 2007

Photovoltaic and wind inverters optimise energy harvesting in installations with multiple PV arrays oriented in different directions.

New from Power-One is the Aurora PVI-6000 Series of photovoltaic and wind inverters.

These grid-tie products use two high-speed, independent MPPT (maximum power point tracking) channels to optimise energy harvesting in installations with multiple PV arrays oriented in different directions.

The amount of available energy is also increased through the use of transformerless designs that provide up to 97% (96.5% CEC) conversion efficiencies.

Bill Yeates, Power-One's CEO, commented; "The PVI-6000 is the first of many exciting new products from Power-One that are designed to further address the fast-growing alternative energy markets".

"In addition to providing unmatched energy harvesting under varying weather conditions, the PVI-6000 Series offers best in class communications capabilities, and a robust design that is designed to provide full-rated power on a continuous basis with a 25 year MTBF".

The PVI-6000 Series provides grid-connected operation certified to international standards.

Additional features include: laptop-free configuration via front-panel mounted buttons, true sine-wave outputs with self-selecting voltage capabilities, less than 3.5% total harmonic distortion (typical), anti-islanding protection, and rugged IP65 (NEMA 4) enclosures.

Communications interfaces include RS485, powerline modem (PLM) and the optional Aurora Easy Communication System, which facilitates remote monitoring via the Internet, analogue modem, or GSM modem.
