Hybrid Power Source

The Lithium-Ion Advantage
Using the reliability of lithium-ion technology, Stellar’s Hybrid Power Source offers robust power for hydraulic equipment operation, with flexible battery capacity that can be upsized or downsized based on operational demands. The system provides up to eight hours of runtime and more than 10 years of life. With up to 12.8 kWh of output, you will have plenty of available power to meet your equipment needs. Designed as the slimmest and lightest configuration in its class, the HPS reduces weight without sacrificing performance. These systems deliver matchless dependability with the most power in the least amount of space. It’s not a battery — it’s a power system.

Versatile Compatibility
Stellar’s hybrid power system is designed to work seamlessly with both traditional internal combustion engine (ICE) and electric vehicle (EV) chassis.

• For ICE chassis, the HPS can be charged using the chassis engine, allowing for a smaller, cost-effective battery setup.
• For EV chassis, the system functions as a standalone unit with a larger battery that is not reliant on chassis charging

This versatility makes the HPS a future-ready solution, keeping pace with the evolving electric power landscape.

Always Ready to Perform
Stellar’s hybrid power system is always ready with multiple options to keep the unit charged. It comes equipped with integrated power electronics, allowing the system to be charged from the chassis onsite or while driving to the next jobsite. Shore power charging is also an option with a standard 120V, 15-amp connection to enable the unit to slow charge while parked for the night or when chassis engine charging is unavailable.

Low Voltage
The utilization of a 48V system enables the entire HPS unit to qualify as low-voltage, removing the need for compliance with high-voltage placarding.

Zero Emissions & Quiet Operation
When using the HPS, the system allows for 100% emission-free operation, reduced fuel consumption, and decreased engine maintenance costs. The flow and pressure control system ensures consistent pressure, even as flow increases, for improved efficiency.

Because it’s electric, Stellar’s hybrid power system is far quieter than diesel and gas engines. This is a direct safety-related benefit because, as a service technician, you may spend your entire career working next to the loud roar of a diesel engine, which can ultimately result in hearing loss.

Working with heavy machinery, you always have to keep a watchful eye out just to see if things are going smoothly and safely. The absence of engine noise provided by hybrid systems enhances jobsite awareness, allowing operators to hear potential issues instead of just an engine rumbling in the background.

Seamless Equipment Integration
The HPS is engineered to integrate directly with Stellar cranes, compressors and stabilizers for optimized performance. It also supports efficient pneumatic operation, with the standard HPS capable of running a 40P compressor—enough power to effectively get the job done.

Equipped for Any Climate
The hybrid renewable energy power source is prepared for multiple climates with internal thermal protection to insulate the energy packs’ core temperature in extreme heat or cold. The HPS also comes equipped with a heating system that will automatically activate to keep the unit’s core temperature above the minimum for charging.

What’s more, the HPS is a great power generating solution for many operations in remote locations.

An Easy Addition
Simplicity in upfitting a service truck is made easy when it comes to the fully self-contained HPS unit. Weighing only 790 pounds and measuring 47″ long x 21″ wide x 28″ high, the system can be side-pack-mounted or mounted in the load bed, lengthwise, making it the perfect addition to any service truck package.
