On-Board Power That Keeps Heavy Fleets Rolling
Long-haul trucks, livestock carriers, and heavy haulage vehicles need reliable on-board power for driver amenities, load monitoring, and site work — without idling a big diesel for hours at a rest stop or loading bay. Zeliox charges off the alternator on the move and delivers silent 240V wherever the truck stops.

Heavy Diesel Idling Costs More Than Fuel
A heavy truck burns 2–4 litres of diesel per hour at idle. Multiply that by mandatory rest breaks, loading dock waits, and overnight stops, and the annual cost per vehicle runs well past what most fleet managers have budgeted — before counting accelerated engine wear and DPF maintenance.
| Idle Fuel Rate | 2–4 L/hr per truck |
| Overnight Idle Cost | $15–$30 per night |
| Annual Idle Fuel | $4,000–$8,000+ |
| Engine Hours | Pushes service intervals |
| DPF Stress | Low-load idle damage |

Silent Power From the Alternator to the Rest Stop
Zeliox stores energy from the alternator while the truck is moving and delivers 240V on demand when the engine is off. Drivers run air-conditioning, fridges, inverters, and monitoring systems from the battery — no diesel burned, no noise, and no engine hours added while stationary.
- Drive Charging: Alternator input at speed
- Silent Output: 0 dB at rest
- 240V Delivery: Aircon, fridges, inverters
- No Engine Hours: Battery handles stationary loads
- Solar Supplement: MPPT input for top-ups
- 5-Year Warranty: LiFePO4 platform
The engine moves the truck. The battery runs the stop.
The Zeliox Advantage
Heavy vehicles burn diesel at a rate that makes idling genuinely expensive. A truck idling overnight at a rest stop or for hours at a loading dock is pouring fuel into the exhaust for air-conditioning, a fridge, and device charging. Over a year, that is thousands of dollars per vehicle. Not to mention engine hours that push service intervals forward. Zeliox mounts in the cab or chassis and charges from the alternator while the truck is moving. When the driver stops, the battery takes over — running aircon, fridges, inverters, and monitoring equipment without the engine. The system also handles site power for livestock monitoring, refrigeration checks, and load equipment that would otherwise need a generator or a running engine.

Frequently asked questions
Can Zeliox run a truck air-conditioner overnight?
Yes, depending on capacity. A configured Zeliox system can power cab air-conditioning, a fridge, and device charging through a standard rest break without the engine running.
Does the system mount in the cab or on the chassis?
Zeliox can be mounted in either location, depending on the vehicle layout and available space. Our team will advise on the best fit for your truck configuration.
