Always there. Everywhere.
The mobile energy storage system: Emission-free, quiet and powerful.

In many areas, such as on construction sites, at open-air events, for first responders or disaster response, traditional diesel generators no longer meet the requirements in terms of sustainability and climate protection.

Environment-friendly energy always available.


The VOLTSTATION® is a powerful energy storage system which offers an environment-friendly, economical alternative that is flexible in use – both mobile and stationary.

The electricity requirements are covered independently of the grid infrastructure, operation is emission-free, and the compact design means it can be used flexibly, wherever and whenever needed. As in our guiding principle: Always there. Everywhere. And in times of rising fuel prices and cost-efficient use of off-peak electricity, our energy storage system is also an attractive solution economically.

Easy to transport – with a Class B driver’s license and a trailer – the VOLTSTATION® is a thoroughly well-thought out energy storage solution.

The reliable energy source for every requirement

There are many good reasons why our mobile energy storage is the solution to ensure a sustainable energy supply for a wide variety of applications.
Developed and produced in Austria! With over 16 years’ battery expertise, we guarantee the use of leading European manufacturing technology.

Awareness is increasingly growing of the need to ban emissions such as CO2 and exhaust gases from urban areas. In the 20 kVA segment the emission-free VOLTSTATION® is the perfect solution.
The mobile energy storage system is substantially quieter compared to diesel gensets, and also follows the trend for freeing urban environments from all noise.

No regular maintenance or servicing work is necessary, so the operating costs are lower and less time and resources are consumed.


Easy to transport
Any driver with a Class B driver’s license can transport the VOLTSTATION® to its place of use quickly and easily using a small single-axle trailer. On site the energy storage system can be moved effortlessly to the desired spot using a crane, forklift or pallet truck.


Battery charge indicator
The charge indicator enables users to monitor the energy consumption so that they charge the battery in good time, thus avoiding unnecessary stoppages.


Easy to use
The labeled controls and user-friendly interface make the system fast to start up and intuitive to use.


Construction sites

The modern construction site is electric, emission-free, clean and quiet. Today clients are increasingly taking note of ecological criteria during tenders.

The VOLTSTATION® is the solution to substantially reduce emissions such as exhaust gases and noise.

Industry and commerce

Our mobile energy store prevents production downtimes at short notice and unplanned scrappage due to power outages.

By smoothing out peaks in power consumption, it also ensures more efficient use of grid connections.

Open­air events

Sustainability is a central topic for organizers of open-air events, because they often leave a high CO2 footprint behind, particularly due to the energy consumption.


The low-noise VOLTSTATION® is an excellent alternative for film and TV productions.

Operating several VOLTSTATIONs® in parallel allows the energy demand to be scaled, guaranteeing smooth operation for a whole day’s shooting without having to recharge.

Charging infrastructure

The VOLTSTATION® offers a rapid and simple energy supply in regions without charging stations.

Charged using photovoltaics, it can reduce the CO2 footprint and optimize costs by charging during low-cost times and using power during the expensive periods.

Disaster response

During large-scale power outages or disasters such as storms, earthquakes or floods, a power supply for the first responders is crucial.

The VOLTSTATION® can be transported rapidly to the place of use on a small car-trailer by any driver with a Class B driver’s license.
