Our Mission

Energy Technologies, Inc. (ETI) is dedicated to providing highly reliable, yet cost effective product solutions for the computer and power conditioning requirements of critical applications including the military, industrial, medical, and telecommunications sectors.

Company Profile

Founded in 1991, Energy Technologies, Inc. has become the leader in rugged power products with their field-proven, highly-reliable and cost effective designs. Utilized in tens of thousands of installations worldwide, these product solutions cover the production, conditioning, storage and control of AC and DC power for a wide range of environments. These rugged products meet the demands and rigors of defense, government, industrial, medical and telecommunications sectors.

Mobile applications include shelters, vehicles, shipboard, submarine, aircraft and field deployment. Stationary applications consist of permanent or temporary facilities, factories, process plants, utilities, networks, even offshore platforms and desert pipelines installations.

Both the Rugged Systems™ and Military Power® (COTS and Mil Spec) lines are comprised of intelligent UPS, power distribution units, frequency converters, inverters and battery systems. Each is available in rack mount, NEMA or custom enclosures suited for mechanical shock, vibration as well as extremes in temperature and humidity. The intelligent features include the ability to monitor and control the equipment and their loads via local and/or remote interfaces such as SNMP and HTTP. The World Power™ versions operate from all voltages and frequencies worldwide including aircraft or vehicular power.

The Tactical Power® series includes deployable inverters, converters, and global UPS that operate from either vehicle DC or whatever AC is locally available. The Tactical Generator® line includes lighter weight, deployable generators and packaged power plants. Tactical Fuel Cells® include complete portable power systems that replace traditional generator sets that are heavier and noisier. Tactical Field Office® systems include modular/deployable field-office desks with built-in power conditioning/backup plus Tactical Computer Workstations® and Tactical Task Lighting™. Operating from available AC or DC power sources, the Tactical ECU™ units provide heating and cooling for shelters and/or equipment enclosures.

The Tactical Solar® family consists of high-performance solar panels that are both rugged and flexible, charge controllers, battery modules and complete solar power solutions for hostile environments. The solar panels configurations include foldable blankets and shelter flies. Tactical Wind Turbines® are light-weight, easily setup power sources that can run independently or as a hybrid system with the solar. These turbines are designed to operate in minimal wind conditions. The Tactical Micro Grid® pulls all of this together with an intelligent controller managing the various power sources, energy storage devices and equipment loads to maximize performance and economy for the given priorities.

From the sedate office and control room environments to the shock and vibration of shipboard and military vehicle applications to the temperature extremes of unprotected desert installations, ETI's products have become the Standard in rugged power applications today.


ETI started in 1991 in an abandoned masonry building originally built as a car dealership in the early 1940's. This was located in a run-down area of Mansfield, Ohio near downtown that the City government considered a blight. We replaced the roof, renovated the inside and set up initial production in 1992. As we grew, we needed more space and began acquiring other distressed properties in the area. We bought the original drive-in restaurant in Mansfield and converted it to Engineering offices. Later we bought the first (in the world) coin-operated laundromat building and converted it to Research and Development. We then acquired a two-story building that was originally a jewelry manufacturer but was converted to slum apartments with lots of drug activity. We gutted the build and renovated it into our Warehouse.

Then we worked with the City to acquire land for future growth. We purchased what was once a farm bureau, then became a bunch of dilapidated and collapsing buildings housing drug deals and stolen cars. The City allocated some funds to help us demolish it all in preparation for a future manufacturing site. Today we have a campus of five buildings and ten 40' ISO containers totaling 30,000 square feet. We have City Planning Commission approved plans for new buildings totaling 30,000 square feet. We took an area of Mansfield that was considered a slum and converted it into a modern and attractive facility with landscaping around each building. The City continues to praise us and the Ohio Governor has been to and spoken publicly at our facilities twice. He even did a ribbon cutting ceremony when we opened our R&D building.


Our R&D has patented new technology that takes organic waste and directly produces hydrogen for use in the growing fuel cell market. This essentially eliminates the need for landfills and thereby eliminating the methane and carbon dioxide that landfills produce. For more details,
