GridTek 10, Utility-Intertie Inverter

BWC has begun shipments of a new, advanced UL-certified, grid intertie inverter system for their 10 kW BWC Excel-S wind turbine. The all-new GridTek 10 "Power Processor" replaces the Powersync inverter, which was first introduced in 1983. Its advanced power switches and digital controls allow home wind turbines to produce true 110-volt power that is easily integrated into the grid. "We are calling it a "power processor" to more accurately reflect the full AC-DC-AC process that the GridTek uses to convert wind power to utility power." notes Mike Bergey, president and CEO of Bergey Windpower Co. Price starts at $7,400. Web: www.bergey.com/News.htm

Thermal Max, Solar Water Heater

Conventional flat-plate solar collectors were developed for use in sunny and warm climates. Their benefits are greatly reduced when conditions become unfavorable during cold, cloudy and windy days. Thermomax solar collectors are specifically designed for operation in all kinds of climates. This superefficient heater system begins with a 60" x 80" roof-mounted model MAZ 2-20S. It is a 20-Tube collector system, complete with fittings and accessories that retails for $1,865.

Solarex, MSX-120 24 volt PV Pane

In the old method of stringing 12-volt PV panels for a home system configured at 48-volts, panels had to be purchased in sets of four or the system simply would not function correctly. Higher voltage panels can mean greater flexibility in system design and more efficient use of mounting space. They are available for $599 in 120w and 110w and output at least 24-volts.
