Limited power? No problem.

Stealth Power’s standalone hybrid generators provide flexible, scalable power for remote power applications, such as oil and gas, mining, irrigation, cell towers, sky watch towers, operating bases, micro-grid operations and unreliable grids.



  • intelligent master control unit that cycles on and off, to optimize performance and conserve fuel
  • remote self-monitoring of fuel use, batteries and generator health, to preserve maintenance and man-hours
  • engineered to eliminate the number-one maintenance issue, wet stacking, to improve reliability
  • designed to operate electrical loads at 12/24/36/48 VDC and 110/220 VAC, with black-start capability of 15 continuous seconds of 2,400 cold-cranking amps

Mobile/Cell Towers

Using the same principles used for idle reduction, Stealth Power has developed a mobile/cell tower fuel-reduction unit that diminishes dependence on generators when grid power isn’t available. In areas where cell towers have high dependence on generators, installing our system can result in 60-80% fuel reduction. It also substantially cuts labor costs to monitor and refill generators.

Using Stealth Power’s fuel-reduction unit, the mobile tower draws from the electric grid and the generator only when the batteries reach 20% of capacity; then, the whole power output of the generator is used to charge the battery, rather than to operate the equipment.

The result* is a 50% reduction in fuel use, a return-on-investment within 18 months and a continued 50% decrease in operating costs; savings are further enhanced through lower fuel-refilling costs and fewer maintenance cycles.

Costs depend on generator size and significance of energy cost differentials during day/night.

In locations that have difficulty accessing power, the power/utility provides a tiered rate structure for using power off‐peak rather than during peak hours.

This load shifting can be as high as 25% of the difference between peak vs. off peak usage. In India, for example, the price difference in an energy unit can be as much as 22.5% if non‐peak hours are utilized. This is a guaranteed savings available every day as the load shifting discount is applied at least 5 days a week. In a test case, we used a 78,000 sq. ft., class A office space which was being utilized at 50%. The system reduced the need for a second generator, reduced fuel consumption by 75% and provided a reduction of power costs by 32%. The system cost was recouped within 9 months and the continued cost savings went directly to the owner’s bottom line.
