Hybrid Power Generation Systems

Our Power Products:

Dewey Electronics Hybrid Power Generation Systems
Dewey’s hybrid generators reduce your use of fossil fuel by 30-90%, cut maintenance cycles from 50% to 87%, and extend the power system’s life by as much as 400%.

Save Fuel, Reduce Maintenance Cycles with Hybrid Power Generation Systems

These generators are built specifically for battery charging, and are available in several configurations and power ranges. All are based upon the 2kW Military Tactical Generator, with added features and capabilities that enhance battery charging and battery life. Our hybrid power generator systems are available in 2.0kW and 4.5kW hybrid power systems and 2kW enclosed hybrid generator.

Available Models

Dewey Electronics Power Products Hybrid 4.5kW Generation System

4.5kW Hybrid Power Generation System

This robust power generator system comprises a 4.5kW 28V DC diesel generator, battery storage, and DC/AC inverter. Built for excellent availability and long life, it features the Dewey-developed auto start generator controller that monitors battery capacity and provides a current limited battery charging feature. This allows the generator to charge lead acid, AGM, Li Ion, or any battery chemistry combination.

Renewable power source integration reduces fossil fuel use, meets power demands

This system also allows for the integration of solar or wind 28V DC sources to supplement the generator and reduces fossil fuel consumption by at least 30% when compared to standard generators of equal size. Dewey’s 4.5kW hybrid system can replace standard fossil-fueled 5kW and 10kW generators and support peak power loads to 12kW for short periods of time.

The components’ modularity and scalability allow you to build a more operationally, cost-effective power due to the system’s composition, inputs, and configuration:

  • System composition:
    • Fossil fuel DC generator
    • Batteries for energy storage
    • Inverters for AC power
  • Inputs for renewable, alternative energy such as wind and solar
  • System configuration – transit cases, ISO container, trailer mounted unit
  • Fossil fuel reduction of 30% before system optimization with alternative energy sources
  • Scalable to the system’s power needs

Dewey Electronics Hybrid Power Generation Systems 2kW Enclosed

2kW Enclosed Hybrid Generator

This enclosed hybrid unit was custom designed by the Dewey Electronics engineering team to house our current limiting battery charging 2kW generator that delivers 28V DC output. The enclosure delivers quieter operation, keeps the air-cooled engine operating in high ambient temperatures and extreme sandy and dusty environments, and enables trailer mounting for off-road applications. Electrically, this hybrid generator (P/N 100950-501) features auto start/stop controls, battery management technologies (battery status monitoring and battery charging), and remote-control capabilities via industry standard data bus.

Additional enclosed hybrid generator features:

  • Digital generator controller
  • Electric self-bleeding fuel pump
  • Enhanced air filtering system
  • Low fuel usage
  • The 2kW power output means less housekeeping

Dewey Electronics Battery Charging Auxiliary Power Units

Battery Charging Auxiliary Power Unit (BAPU)

Based on our 2kW military heritage, enables the battery charging auxiliary power unit (BAPU) provides a simple power source that is lightweight yet highly reliable and easy to maintain. It is an open frame, heavy fuel generator set that provides a full 3kW military-rated 28V DC power supply in temperatures ranging from -35° F to 130° F, making it suitable to charge batteries—across multiple battery chemistries—under extreme temperatures. The optional enhanced air filter system also enables the BAPU to also operate in extreme sandy and dusty environments.

This basic design can be configured to provide additional power levels such as:

  • 3.5kW of current limited 28V DC at 70°F, derated power output to 130°F
  • 4.5kW of current limited 28V DC at 70°F, derated power output to 130°F

Features that offer flexibility in the field:
The BAPU is designed to be mounted on the ground or on a vehicle with mounting feet adapters.

  • Local control panel that provides voltage and current displays
  • A current limiting voltage regulator
  • Self-bleeding fuel system for vehicle or remote fuel tank interconnections
  • Option to cable a remote-control panel to the unit for monitoring and control of the BAPU from over 30 feet away
  • Electric fuel pump with 72-inch lift
  • Electric start from customer battery
  • Meets Mil-Std-810 sand and dust
  • Remote control via optional control box
  • Simple one-switch operation
