Polar Power, Inc. announced it has received certification from the Environmental Protection Agency (EPA) for Toyota 1KS natural gas and LPG engines used in Polar’s DC power systems. As part of Polar Power’s ongoing diversification strategy, the company has been working to introduce lower emission, fuel efficient prime power and solar hybrid power systems targeting telecom, residential and commercial markets in sub 40 kw microgrid applications. The company’s engineering team has worked for over twelve months to integrate proprietary control technology with a long-life Toyota engine and Bosch engine controls designed to address the growing market for prime power, CHP and backup power needs worldwide. Polar is currently the only US company to achieve EPA certification for this Toyota 1KS engine that operates on natural gas and LPG (liquid petroleum gas refers to propane or combinations of propane and butane gases).
