Introduction: A New Benchmark in Mobile Power
The ISUZU NPS has long been the backbone of service fleets, remote operators, and off-road work trucks. From mine sites to construction zones, this rugged 4×4 platform has proven its reliability. But what if one of the toughest trucks in Australia could also become a mobile powerhouse, running hydraulic services, tools, and onboard electronics without a separate generator?
That’s exactly what Safiery has achieved with the launch of its 48V 8kW Belt Motor Generator, engineered specifically for heavy-duty service trucks like the ISUZU NPS. And it doesn’t stop there — the system can also split this power with up to 3kW at 24V and/or 12V, powering everything from hydraulic pumps to work lights and communication gear.
With this breakthrough, the ISUZU NPS has earned a new title: the Power BEAST.
The Challenge: Powering Service Trucks Efficiently
Service trucks, particularly those equipped with hydraulic equipment, demand serious electrical power. Traditional setups often rely on:
Separate diesel gensets mounted on the truck, adding weight, noise, and fuel complexity.
PTO (Power Take-Off) systems connected to the driveline, which can be costly, maintenance-intensive, and difficult to retrofit.
Alternator upgrades, which are typically limited to 12V or 24V and struggle to provide stable high-power output for demanding loads.
For operators in industries like mining, construction, rail, and utilities, these solutions add cost, complexity, and downtime. What was missing was a clean, compact, and integrated way to generate high levels of DC power directly from the truck’s engine.
This is a SECOND “Alternator”
But it's not an old school alternator but the new high efficiency permanent magnet generator. It produces 8kW of power and at least 2kW at Idle.
It has an isolated ground (or negative) so it doesn't in ANY way connect to the trucks starter motor nor the trucks 24V system. It is totally isolated and independent.
It is totally isolated and independent power system.
Safiery’s Solution: The 48V 8kW Belt Motor Generator
Enter Safiery’s 48V Belt Motor Generator — an alternator-class unit that redefines what’s possible for mobile service power.
8kW continuous output at 48V, Split into 48V and either 24V or 12V
The split power can be up to 3kW at either 24V or 12V outputs
Designed for integration with hydraulic services, tools, lighting, and communications
Belt-driven from the engine, eliminating the need for separate PTOs or gensets
This isn’t just an alternator upgrade — it’s a complete rethink of how trucks can generate and distribute power. By tapping directly into the engine’s belt drive, Safiery has created a system that’s lighter, cleaner, and more reliable than conventional setups.
Why 48V? The Future of Mobile Power
The shift to 48V systems has been happening across industries, from automotive hybrids to marine applications. Here’s why it makes sense for service trucks:
Higher efficiency: 48V allows for lower current at the same power, reducing heat and cable thickness.
Better integration with lithium batteries: 48V packs charge faster, hold more energy, and deliver higher output for demanding tools.
Scalability: With 8kW at 48V, the ISUZU NPS can now power everything from welding gear to hydraulic pumps.
By pairing 48V with 24V and 12V outputs, Safiery ensures total system compatibility. Operators can run their existing 12V accessories while preparing for a future that’s increasingly 48V-centric.
This is 85% Efficient when Hot. A traditional Alternator is only 50% when hot.
Real-World Application: Hydraulic Service Trucks
One of the first deployments of the 48V Belt Motor Generator is on ISUZU NPS service trucks that run hydraulic equipment. Traditionally, these trucks carry bulky gensets to power hydraulic pumps. With Safiery’s system:
The 8kW 48V output drives hydraulic systems directly.
The 3kW 24V/12V outputs handle lights, radios, diagnostics, and auxiliary tools.
The truck remains lighter, quieter, and more efficient without an extra genset.
This results in lower fuel consumption, less maintenance, and more payload capacity — critical factors in industries where every kilogram and every minute counts.
Benefits Over Traditional Systems
1. No More Gensets
Operators can finally retire their noisy, heavy, and maintenance-hungry diesel gensets. The belt generator provides all the power they need whenever the truck is running.
2. Compact and Lightweight
By integrating into the existing engine system, the Safiery generator eliminates bulky add-ons. This means more space for tools, equipment, or payload.
3. Multi-Voltage Flexibility
Whether it’s a 48V lithium pack, a 24V compressor, or a 12V lighting rig, the system powers it all.
4. Lower Total Cost of Ownership
Fewer moving parts, no separate fuel system, and less downtime mean real savings over the life of the vehicle.
5. Australian Toughness
Designed and tested in Australia, the system is built for heat, dust, and rugged work environments.
Adding Solid State Lithium Batteries
The batteries are the centre of the energy universe and have to be “managed” CAN BMS that broadcasts the maximum charge and discharge rate:
The 8kW 48V output synchronises directly with the battery BMS command for absolute safety and compliance.
The 3kW 12V outputs Operate from this battery bank directly and there is NO NEED for an additional 12V battery.
This results in an electrical system that is simpler with a single managed battery system all visible on the Victron One Touch Display.

ISUZU NPS: The Perfect Match
The ISUZU NPS is already known as a go-anywhere, do-anything service truck. With 4×4 capability, robust chassis, and strong payload ratings, it’s the platform of choice for countless operators.
By pairing it with Safiery’s 48V Belt Motor Generator, the NPS gains a new dimension:
A mobile energy hub that supports hydraulics, tools, and electronics.
The ability to operate as a field service station without additional equipment.
An edge over competitors, especially for operators bidding on jobs requiring flexible, efficient power solutions.
Industry Impact: A Game-Changer for Fleets
The implications extend well beyond individual trucks. For fleet managers:
Simplified maintenance – fewer systems to service.
Standardized power – all trucks can deliver consistent output across 48V, 24V, and 12V.
Improved uptime – reduced failures from separate gensets or PTO systems.
Better sustainability – lower emissions and reduced fuel burn.
In industries under pressure to cut costs and emissions, this technology provides a clear path forward.
