OneBox Energy
A unit that enables energy conversion and distribution for your boat.
DEFINITION
Heart of the energy-propulsion system
The OneBox is the central module of every JOOOL hybrid-electric system. It connects all energy sources : shore power, solar, generator, to battery storage and all onboard consumers, and coordinates every energy flow through the EPMS intelligence layer. Available in two configurations for different vessel profiles and use cases.
AUTOMATED ENERGY MANAGEMENT
OneBox Energy : energy management and silent mooring
The OneBox Energy manages all onboard power, battery storage, solar input, shore charging, and generator management, while the vessel retains its existing thermal propulsion. Hotel loads run silently from battery storage at anchor and in harbour. The EPMS manages generator cycling automatically, minimising runtime and fuel consumption.
- For all vessel sizes: 40 to 120 ft
- Retains existing thermal propulsion: no engine replacement
- Silent hotel loads at anchor: lighting, refrigeration, AC, watermaker
- Automated generator management: starts and stops based on battery state
- Solar and shore power inputs optimised simultaneously
- Up to 152 kWh battery storage per unit : up to 3 units in parallel

QUESTIONS
Everything you want to know
Yes. The battery packs, EPMS, and installation architecture are shared across both configurations. Upgrading involves replacing the OneBox module and adding the PowerPod, the electrical infrastructure already in place is compatible. JOOOL's engineering team can advise on the upgrade pathway for each vessel.
Up to three OneBox units can run in parallel on the same vessel, for total battery storage up to 456 kWh and combined AC output up to 18 kW. For the Propulsion configuration on a catamaran, two OneBox Propulsion units drive two PowerPods independently.
