Sustainable Energy Reports Successful Inverter TestsJune 12, 2002 by Jeff Shepard
Sustainable Energy Technologies Inc. (Calgary, Alberta) reported that in stand-alone tests conducted by Sandia National Laboratories (Albuquerque, NM) the company's 5kW power inverter demonstrated better than 93-percent power conversion efficiencies across a full power range, ranking it among the most efficient inverters at this power rating in the industry.
"Perhaps the most significant result of this testing is the demonstration of our inverter’s ability to maintain a high conversion efficiency across the full power range," stated Brent Harris, director of technology for the Sustainable Energy. "Although competitive inverters often have high peak efficiencies, the efficiency drops off rapidly as the load increases beyond about 20 percent of full load. Full load efficiency is very important since the bulk of an inverter’s energy transfer occurs at higher power levels."
