Diesel DC Generator 24V and 48V Battery Charging Generator
Designed for Hybrid Power Systems
The AGi4P-DC diesel DC generator is designed for reliable battery charging in hybrid power systems, telecom infrastructure, and off-grid energy systems. Powered by a Perkins 402F-05G two-cylinder diesel engine and paired with a Linz Electric DC alternator, this generator delivers regulated 24V or 48V DC output with extremely low ripple and adjustable current limiting.
Unlike high-speed air-cooled generators commonly used in telecom systems, the AGi4P-DC operates at 1800 RPM with liquid cooling, enabling quiet operation and continuous duty performance in demanding environments.
This makes it an ideal battery charging generator for solar hybrid systems, telecom power sites, and remote energy storage applications.
Key Features of the AGi4P-DC Diesel DC Generator
Continuous Duty Operation
Key design advantages include:
- Liquid-cooled Perkins diesel engine
Low 1800 RPM operation for durability and quiet performance
- Industrial generator design suitable for continuous operation
- Long service intervals and global Perkins parts support
These features make the generator suitable for remote installations where reliability is critical.
Direct DC Battery Charging
The AGi4P-DC produces regulated DC power directly, eliminating the need for external rectifiers or AC-to-DC conversion equipment.
Benefits include:
- Higher system efficiency
- Reduced electrical components
- Lower installation complexity
- Improved overall system reliability
Extremely Low Output Ripple
The Linz DC alternator produces less than 1% output ripple, even without batteries connected.
Benefits include:
- Cleaner charging current
- improved battery life
- stable operation for sensitive DC loads
This makes the generator suitable for telecom equipment, battery banks, and DC power systems.
Adjustable Voltage and Current Limiting
The generator includes integrated voltage regulation and current limiting capabilities.
This allows operators to:

- control charging current
- Protect battery banks from excessive charge rates
- integrate easily with hybrid energy systems
Quiet Low-RPM Diesel Operation
Many small generators operate at high speeds between 2800 and 3600 RPM.
The AGi4P-DC operates at 1800 RPM. This lower speed provides:
- Reduced noise levels
- Longer engine life
- Lower vibration
- Improved fuel efficiency
This makes it suitable for installations near sensitive environments such as telecom shelters and remote monitoring sites.
