The same power as a 6.5 kVA generator, emission-free.

Work with the same power you’re used to, but without emissions and noise. The Wattsun Ventus sets the new standard for powering all your tasks, wherever you are.

Mobile and robust.

The Wattsun Ventus is a powerhouse. Its waterproof and rugged casing allows you to work anywhere and anytime. Simply roll or lift the Wattsun Ventus to the right location and get every job done.

Charged at lightning speed.

Charge the Ventus via the mains power up to 3600 watts in 4 hours, or opt for green solar energy. The system features 2 built-in MPPT chargers with a total charging capacity of 6500 watts, allowing you to fully charge the Ventus in just over 2 hours.

Robust Casing

Thanks to its robust casing, the Ventus can withstand rough handling, allowing you to rely on your power source in all weather conditions.

Solar charging

Charge the Ventus directly with solar energy. Thanks to the two integrated MPPT chargers, you can fully charge the Ventus within 3 hours. Each charger has an MPPT range of 150V ~ 425V with a charging current of up to 13A.

3600W charging speed

Charge up to 3600 watts via mains power. Prefer a lower amperage? Adjust the charging speed via the touchscreen. You can choose from 5A, 8A, 13A, or 16A charging options.

Ergonomic handle

The Ventus is easy to move thanks to the integrated ergonomic handles.

Touchscreen display

The intuitive display provides an overview of your current energy consumption, remaining battery life, charging speed, and much more.

Lifting eye

With the lifting eye on top of the battery system, you can easily move the Ventus using a forklift or crane.

15 kWh capacity

With 15 kWh of capacity, the Ventus is the mobile battery system with endurance. You'll get through the day worry-free, wherever you are.

Mobile

The Wattsun Ventus comes standard with two swivel casters and two fixed wheels. It can be equipped with various chassis options to fully meet your needs.

Bumpers

When you need to perform at various locations, you also need to be able to withstand some rough handling. The bumpers absorb the initial impact and also ensure that the connectors are protected.

Fuses

Each outlet is equipped with 16A fuses to prevent overload.

Frequently asked questions
01 How does the insulation monitor of the Wattsun Ventus work?

In a residential home, the power grid is protected by a residual-current device (RCD). However, this only functions properly with a reliable protective earth (PE).

When using a mobile power solution such as the Ventus, it is often difficult to implement a proper protective earth.

Nonetheless, the NEN1010 standard requires ensuring the safety of people working with the AC generator. The standard mandates the creation of a floating network system (IT system) in combination with an insulation monitor.

The insulation monitor ensures that the 230Vac is automatically disconnected if the insulation resistance becomes dangerously low.
The insulation resistance refers to the resistance between the 230Vac and the touchable parts of the device, such as the metal casing.

02 How can I move the Wattsun Ventus?

You can move the Ventus in two ways: thanks to the (adjustable) wheels under the battery system and the handles on top of the casing, you can easily roll the Ventus from A to B. Additionally, it is possible to move the Ventus using the lifting eye on the top of the battery system.

03 What is the life-expectancy of the battery

All batteries loses efficiency over time. To indicate this efficiency we use the term cycles. One cycle is the same as fully using the battery from 100% to 0%. To benchmark the amount of cycles a battery can handle, 80% is set as the maximum amount of battery degradation. For example, if you charge the Wattsun three times a week, you'll only reach a 20% loss of capacity after 5 years. This means you can still fully utilize the power of the Wattsun, although the battery capacity will have slightly decreased.

 

Wattsun Dock 2000, Wattsun Dock 2000+, Wattsun Pack 1.6

We guarantee a battery life of 600 cycles up to 80%.

 

Wattsun Dock 3000, Wattsun Pack 3000

We guarantee a battery life of >1000 cycles up to 80%.

 

Wattsun Ventus

We guarantee a battery life of >6000 cycles up to 80%.

04 What is the maximum capacity of Wattsun?

The third generation Wattsun Pack 3000 offers 2.3 kWh capacity and Wattsun Dock 3000 offers 1.8 kWh capacity which is an 41% increase compared to the previous generation Stack.

By stacking four Wattsun Pack 3000's on top of a Dock 3000 you can extend your capacity up to 11 kWh.

Do you still need more capacity and perhaps more power? Take a look at the Wattsun Ventus. The Wattsun Ventus provides 5000 W of power and 15 kWh capacity on its own.
