Inverters Receive Positive Reviews

SatCon Technology’s power inverters for on-site power generation have been determined to be in compliance with the “Standard for Inverters, Converters, and Controllers for Use in Independent Power Systems.

Cambridge, Massachusetts – October 23, 2002 [SolarAccess.com] SatCon Technology’s power inverters for on-site power generation have been determined to be in compliance with the “Standard for Inverters, Converters, and Controllers for Use in Independent Power Systems, UL 1741” by the Underwriters Laboratories Inc. The independent, not-for-profit product safety testing and certification organization tested SatCon’s power inverters for compliance with standards for alternative energy, distributed and grid parallel energy generation systems. According to SatCon, their power inverter is the highest power rated on-site generation inverter to comply with the UL 1741 standard, an important step in gaining approval for installations in California where such compliance is a requirement. “We are beginning to see the implementation of a whole new power system that uses on-site power generation tied to the existing utility grid to provide users with high-quality, reliable power,” said David Eisenhaure, SatCon president and chief executive officer. “Recently, California passed a Renewable Energy bill requiring that 20 percent of its electricity come from renewable sources,” said Eisenhaure. “With the uncertainty of an uninterrupted supply of oil from the Middle East, we believe that American energy independence will become an increasingly important issue for U.S. industries. By meeting the UL 1741 requirements, SatCon’s Power Conditioning Systems (PCS) are well-positioned to become the leading choice for customers interested in creating their own distributed power using fuel cells in conjunction with, or completely separate from, the utility grid. In addition to fuel cell applications, these UL compliant inverters will be suitable for photovoltaics, micro-turbines and other on-site power generation systems.” “Compliance with UL 1741 is a requirement for interconnection in California, long known as being in the forefront of energy legislation. We anticipate other states will follow shortly,” said Eisenhaure. The power inverter includes an “anti-islanding” protection feature for detecting when the utility grid is out of tolerance or “black.” The onboard disconnect scheme automatically disconnects the inverter output from the grid to provide seamless transition from “grid connected” to “standalone” mode, preventing power flow to the black grid. Thus, a manufacturing facility that wants to be independent from the power company can generate its own power from a fuel cell system using SatCon’s PCS to generate quality, reliable and interruptible power, said the company.
