The new
Wattsun® Ventus 12K
Work with mobile three-phase power. Anywhere you go.
The Wattsun Ventus 12K makes professional three-phase power mobile. With 12 kW of continuous power, this compact battery system provides 400V exactly where the work happens: without a fixed grid connection, when grid capacity is insufficient, or when additional energy security is needed. Ready for immediate use, virtually silent, and with zero emissions.
Why Ventus
On site, only one thing matters: the work needs to keep moving. That requires three-phase power that is quick to deploy, capable of powering heavy equipment, and reliable under changing conditions. That is exactly what the Ventus 12K was designed for.

The silent power that moves with you
The Ventus 12K delivers 12 kW of continuous three-phase power, comparable to the power class of a 15 kVA generator. Thanks to its compact design and significantly lower weight, the system can easily be moved wherever three-phase power is needed. Roll, hoist, or lift the Ventus 12K into position, connect your equipment, and get straight to work.
Mobile power for all sectors
Security & Safety
Power for incident sites, mobile command posts, emergency shelters, communication systems, and temporary healthcare facilities. Suitable for situations where a rapidly deployable and reliable power supply is essential.
Construction
Three-phase power for construction hoists, welding equipment, pumps, electric equipment, mobile workshops, and temporary facilities. One mobile system for a wide range of tasks on the construction site.
Events & Media
Power for stages, lighting and sound, production vehicles, film sets, hospitality, and temporary production sites. Quiet and with zero local emissions, allowing the system to be used close to audiences, crew, and equipment.
The Ventus 12K at a glance
- Hybrid off-grid operation For fully off-grid environments, the Ventus 12K combines battery capacity, solar energy, and a generator. The system automatically switches between these power sources, providing a reliable energy supply without manual management.
- 230 V to 400 V In situations where only 230V is available, the Ventus can be charged or powered from this supply and then provide 400V output. This makes the system suitable for locations with limited infrastructure where three-phase power is unavailable.
- Solar charging The Ventus supports charging via solar panels thanks to its wide MPPT range. This allows a variety of configurations, from 8 to approximately 80 panels. This makes the system highly flexible for projects where solar power is the primary energy source, regardless of location.
- Emergency power The Ventus 12K can function as an emergency power supply. In the event of a grid outage, the system switches to battery power within a maximum of 80 ms. This rapid switchover time keeps interruptions to a minimum.
