By combining a Xantrex SunTie XR Grid-tie Inverter with Atlantis Energy System's Sunslates® roofing product, the roof of a house can act as both a roof and a power plant simultaneously.

LAS VEGAS, NEVADA, USA, January 19, 2004 - Xantrex Technology and Atlantis Energy Systems are offering a new inverter and solar panel combination designed to make it easier for home builders to install renewable energy systems.

By combining a Xantrex SunTie XR Grid-tie Inverter with Atlantis Energy System's Sunslates® roofing product, the roof of a house can act as both a roof and a power plant simultaneously.

"We're working with Atlantis Energy Systems to make it easier for homeowners to participate in the emerging small-scale green power market," said Lloyd Gomm, Xantrex director of marketing operations. "The combined system is designed to make the installation of solar power systems easier and more affordable than ever before."

Sunslates® are an advanced photovoltaic roofing product that collect the Sun's energy and turn it into DC electricity. A Xantrex SunTie XR inverter turns solar electric power into utility grade AC electricity, which is used either in a home or fed back to the power company.

The Xantrex SunTie XR is a quiet, efficient grid-tie inverter that offers industry-leading performance and maximum energy harvest. When connected to the electrical grid, it literally spins the meter backwards by supplying any excess power produced to the utility company.

Sunslates® are a fiber cement slate roofing product based on the Swiss Eternit system. The system is popular in Europe and has been used for 60 years with great success. An installation of 216 Sunslates® (about 300 square feet) will cover 60 to 80 per cent of the power needs of a typical residence.

"Atlantis Energy Systems is committed to integrating solar systems into the design and construction of new homes," said Joe Morrissey, Atlantis vice president of sales. "We believe the combination of Sunslates® and Xantrex Inverters makes for the safest grid-connected solar system on the market today."
