A diesel DC generator is a dependable source of direct current (DC) electricity powered by a diesel engine. Whether you’re running equipment in remote areas, charging battery banks, or powering DC-driven systems, a diesel DC generator offers an efficient, long-lasting, and fuel-friendly solution. At Innotec Power, we design high-performance DC gensets built for industrial, commercial, and off-grid applications, delivering stable DC output at 48V, 72V, or higher.
We specialize in rugged and compact diesel-powered DC generators that are available in various capacities, including 5kW, 15kW, and 20kW, with customizable voltage outputs to match your specific requirements.
What is a Diesel DC Generator?
A diesel DC generator combines a diesel engine with a direct current generator to supply DC electricity directly, without requiring conversion from AC. Unlike traditional AC generators that need rectifiers or inverters, DC generators produce power natively in the format required by many modern systems — especially in telecom, electric vehicles, battery charging, off-grid setups, and marine applications.
DC generators offer smoother voltage regulation, better control, and higher energy efficiency in systems designed around direct current.

Why Choose Diesel-Powered DC Generators?
There are many reasons why industries choose diesel DC gensets over AC-powered ones:
- Fuel Efficient: Diesel engines consume less fuel and deliver better efficiency under load conditions.
- Long Life Span: Diesel engines are renowned for their exceptional durability and ability to withstand extended working hours.
- No AC-DC Conversion Losses: Direct DC output eliminates the energy loss that happens during AC to DC conversion.
- Low Maintenance: Fewer components compared to inverter-based systems result in easier upkeep.
- High Torque and Stable RPM: Ideal for generating consistent DC power, particularly for battery charging or electric drives.
Whether you need a 48V diesel DC generator, a 5kW remote power supply, or a 20kW genset for industrial use, our solutions are designed for efficiency, compactness, and reliability.
