Ideal Power's Grid-Resilient 125kW Power Conversion System Receives Certification for UL1741 Conformance

Newly Certified Offering Brings Ideal Power Into Large C&I and Utility Storage Space With Product Scalable for Megawatt-Plus Sized Applications

AUSTIN, TX -- 10/20/15 -- Ideal Power Inc. (NASDAQ: IPWR), a developer of innovative power conversion technologies, announced today that its Grid-Resilient 125kW Power Conversion System has been certified for UL1741 conformance by a Nationally Recognized Testing Laboratory. The newly certified 125kW product brings the flexibility and efficiency of Ideal Power's patented Power Packet Switching Architecture™ (PPSA) to energy storage applications requiring larger, more powerful power conversion systems.


Ideal Power's grid-resilient power conversion system features microgrid-forming capabilities that enable back-up power for critical loads in the event of grid challenges, such as power outages. They are also software configurable to enable operation in both 50Hz and 60Hz environments, allowing customers worldwide to support both grid-tied and off-grid applications.

"Our 125kW system represents the latest product and market expansion efforts for Ideal Power," commented Ryan O'Keefe, Senior Vice President of Business Development at Ideal Power. "Our grid-resilient products already support global 50Hz and 60Hz geographical markets, but the 125kW system now adds more power to our portfolio which will accelerate our expansion into larger system installations and megawatt-sized utility projects."

The UL1741 standard is a benchmark for safety and compatibility of inverters, converters, controllers and interconnection system equipment used with distributed energy resources on the electric grid in the U.S. and Canada and certification for conformance to UL1741 is required for such systems to be connected to the utility grid.

TRA SNOW AND SUN - SOLAR TILE MOUNT

TRA SNOW AND SUN - SOLAR TILE MOUNT

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
