Xantrex inverters provide power for new amphitheatre in Arizona

SW Inverter/Chargers from Xantrex Technology (TSX:XTX) are playing an integral role in delivering electricity to the Highlands Center for Natural History's new amphitheater.

PRESCOTT, ARIZONA, U.S.A., June 4, 2004 - SW Inverter/Chargers from Xantrex Technology (TSX:XTX) are playing an integral role in delivering electricity to the Highlands Center for Natural History's new amphitheater.

The Center, located near Prescott, Arizona, installed a renewable energy system to power the 50-seat amphitheater because of its remote, off-grid location and to support its mandate to help children and adults discover the wonders of nature and become wise caretakers of the land.

"We wanted to encourage more use of renewable energy by demonstrating how it works, through educational programs on site, and by providing information to visitors," said Nichole Trushell, Executive Director of the Highlands Center for Natural History.

The Center has a 1.2 kW solar installation that includes Xantrex Inverter/Chargers, which convert the DC energy produced by the solar panels into AC power used at its amphitheater. Since the amphitheatre is not connected to utility power, its renewable power system includes a backup generator for times when there is not enough solar power. The Inverter/Chargers also ensure the batteries that store power maintain maximum charge, while minimizing the generator's run-time. The system was installed by Sun Amp Power Company of Phoenix, Arizona.

"We installed two Xantrex SW 5548s in the first phase of the project," said Jon Walker of Sun Amp Power Company. "They are being used to provide power for the amphitheater, the water and irrigation systems and lighting for pathways."

The Center will soon be building a new 4,000 square foot learning center and more SW 5548 Inverter/Chargers will be added as the renewable energy system expands to accommodate the additional power requirements.

The Highlands Center has encouraged the study of the natural sciences in an outdoor setting for more than a decade. The Center's programs and materials reach over 10,000 children and adults throughout central Arizona.

Equipment installed at the site:
- Two Xantrex SW 5548s
- Trojan L16 battery bank
- LED very high efficient pathway lighting
- Compact lighting
- 12 kW Kohler propane generator - connected to the SW Inverter/Chargers and set in auto-start mode
- Unisolar PV L64 solar panels 1.2 kW size array

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
