Zeliox Eco III: The Industrial Mobile Power System

The Zeliox Eco III is the ultimate silent generator for commercial applications, engineered to power heavy-duty equipment where grid power is not an option. It is built around a massive 2.6 kWh LiFePO4 battery, providing the high capacity and industrial-grade reliability needed for the most demanding off-grid worksites. Its colossal 3000W Pure Sine Wave inverter is designed to run power-hungry machinery like welding equipment, high-pressure cleaners, and chainsaws, delivering clean, stable energy that functions as a superior backup power supply.

This unit is a complete, self-contained 12v power system, offering unparalleled charging flexibility for any professional fleet. It is fully compatible with modern Euro 6 smart alternators and can be charged by an Electric Vehicle (EV). For rapid deployment, its advanced shore power connection (120A) achieves a full charge in as little as 1 hour and 45 minutes.

Key Features Include:

Reclaim Your Day. Install in Minutes, Not Days

This is a true all-in-one lithium power supply, not a puzzle box of parts like older units. Forget spending up to 4 hours wrestling with complex electrical systems. Our easy-install power system connects in a fraction of that time, eliminating costly labor and the fatal connection errors that plague multi-component setups.

Stop Waiting. Start Working. Power Up Faster

The Zeliox Eco III is a fast-charging power station built for professionals who value time. Our superior shore power charging and powerful alternator to battery charger ensure you arrive at the job site with a fully charged leisure battery, ready to work, not waiting to power up.

Power Through Winter. The Eberspacher Zeliox Works When Other Batteries Die

A standard lithium battery that won't charge below 0°C is a liability, not a professional tool. Our self-heating LiFePO4 battery is the definitive all-weather off-grid power solution, with an integrated cold weather power pack that guarantees performance down to -20°C. Don't let your power system dictate your work schedule; this is the end of seasonal downtime.

Dedicated Remote Support

This app-controlled solar generator delivers total system intelligence, not just a primitive voltage gauge. The Eberspacher app provides historical event logs, data readouts, software updates, and the ability for our dedicated support team to diagnose any faults remotely. Stop guessing about your power; start making data-driven decisions that increase efficiency and uptime.

Unleash Maximum Power. Run Heavy-Duty Equipment

The Eberspacher Zeliox Eco III is the pinnacle of mobile power. We’ve engineered this beast with an immense 3000W pure sine wave inverter and a massive 2.6 kWh battery—double the capacity of the Eco II. This isn't just for tools; it's for running heavy-duty, power-hungry equipment and multiple appliances simultaneously. When the job demands everything, the Eco III delivers without compromise.

5-Year Warranty. A 5-Year Warranty Isn't a Bonus. It's Our Standard

A company's warranty reveals its confidence. We back our entire inverter charger, including the critical 12V lithium battery, for a full 5 years—more than double the hardware protection on competing systems. Stop gambling on short-term promises; get the long-term security your portable power station demands.
