48 Volt DC Generator

From $5,893.08

Industrial diesel generator designed for direct 48-volt battery charging.

This 48 Volt DC Generator provides efficient charging for large battery banks used in off-grid power systems, telecom infrastructure, and solar hybrid installations.

Why a 48 Volt DC Generator is better for battery charging

This diesel-powered generator produces a regulated DC output designed specifically for charging 48-volt battery banks used in off-grid power systems, telecom installations, and solar hybrid setups. Unlike AC generators paired with battery chargers, this system delivers direct DC power for higher charging efficiency and lower losses.

Why this DC generator matters

  • Direct DC charging for 48-volt battery banks
  • Adjustable charging voltage for different battery chemistries
  • No rectifier losses found in AC generator + battery charger systems
  • Fast, fuel-efficient charging
  • Works with two-wire auto-start systems
  • Low ripple DC suitable for lithium and telecom batteries

What it powers

  • Off-grid cabins and battery-only systems
  • Solar + battery hybrid setups
  • Telecom cabinets and remote sites
  • Energy storage systems requiring clean DC charging

Included with the generator

  • Hatz diesel engine generator set
  • Built-in fuel tank
  • Frame + vibration mounts
  • Glow-plugs and instrumentation
  • Optional auto-start controller (if selected)

AGi4H-48: The 48V DC Industrial Power Solution

48 Volt DC Generator for Battery Charging and Hybrid Power Systems

The Aurora AGi4H-24 is a 48 Volt DC Generator designed specifically for charging battery banks in off-grid and hybrid power systems. Powered by the reliable Hatz 1B30E industrial diesel engine and paired with a Linz Electric ESA2-48/125 9-phase DC alternator, this generator produces regulated DC output for efficient battery charging without the losses found in typical AC generator and charger combinations.

By generating DC power directly, the system simplifies installation, improves charging efficiency, and reduces the number of components required in battery-based power systems.

Why Use a DC Generator for Battery Charging?

Many battery systems use a conventional AC generator together with a charger or rectifier to convert AC power to DC. A dedicated 48 Volt DC Generator eliminates this extra conversion step.

  • Direct DC output for charging 48-volt battery banks
  • Higher charging efficiency compared with AC generator + charger systems
  • Fewer electrical components to install and maintain
  • Cleaner DC output suitable for modern battery systems
  • Simple integration with battery-based hybrid power systems

Key Components

  • Engine: Hatz 1B30E single-cylinder air-cooled industrial diesel engine
  • Alternator: Linz Electric ESA2-48/125 brushless 9-phase DC alternator
  • Controller: Optional DynaGen TG410 generator controller
  • Starting System: Electric start with optional automatic start capability

DC Charging Performance

The Linz Electric ESA2-48/125 alternator is designed specifically for low-voltage DC generation and battery charging applications. It provides adjustable output voltage from 45 to 60 VDC and can deliver up to 125 amps of charging current with very low output ripple.

This clean and stable DC output makes the generator suitable for charging large battery banks used in telecom systems, solar hybrid installations, and remote energy storage systems.

Automatic Operation with the TG410 Controller

When equipped with the DynaGen TG410 controller, the generator can operate automatically as part of a hybrid power system. The controller provides engine monitoring, safety shutdowns, and configurable alarms.

The generator can also integrate with inverter systems or battery monitors using a simple two-wire start signal. When the battery voltage drops below a set threshold, the generator can start automatically, charge the battery bank, and shut down once the batteries are fully charged.

Typical Applications

  • Off-grid cabins and battery-based power systems
  • Solar hybrid energy systems
  • Telecom shelters and communication towers
  • Remote monitoring and instrumentation sites
  • Energy storage systems require reliable DC charging

A Practical Battery Charging Generator

The Aurora AGi4H-48 is built for applications where dependable battery charging is critical. By producing regulated DC power directly, the generator reduces system complexity and provides an efficient solution for off-grid and hybrid energy systems.
