Mobile three-phase current for construction sites, events and professional applications

The lightest three-phase unit on the market

Whisper quiet, clean and maintenance-free

The ecoPowerTrolley does not cause any noise or pollutant emissions. Neither fossil fuels nor lubricants are used for operation. This allows you to concentrate on the essentials even in a sensitive environment.

Powerful household and three-phase electricity

Operate one or more devices with a total of over 1'000 watts of power for more than seven hours, even under adverse conditions. Even powerintensive applications get by without the need to run 400V (three-phase) power cables. The battery is fastchargeable and recharged in two hours

Lower total costs of ownership than classic generators

With the integrated lithium-ion battery of the latest generation, you rely on an economical energy supply. Even compared to weaker and inexpensive classic gensets, life cycle costs are reduced due to lower running expenses.

Mobile three-phase current for remote or powerless locations

With the ecoPowerTrolley, fitters and emergency personnel can supply any location with powerful three-phase current. The capacity is sufficient for the daily use of numerous professional devices and machines. If required, two ecoPowerTrolleys can be connected in parallel to double the continuous operating time.

Electrifying autonomous construction containers and shifting construction sites

Until now, conventional generators were part of everyday life on remote construction sites. The ecoPowerTrolley alternatively operates both local installations and changing sites without interruption. With a suitable PV system, the autonomy is extended considerably. Intermediate charging with a generator is also possible.

Powerful live event in the city and countryside

The ecoPowerTrolley supplies power for the exhibition stand on wheels or for the food truck. It also supplies a complete DJ set-up or the sound system for the band performance with very good performance.

Charging everywhere instead of towing

The ecoPowerTrolley is used to bridge the gap until the next electric charging station if the electric car breaks down with an empty battery. The fully charged ecoPowerTrolley provides power for up to three times the ~20 km range of the electric vehicle. There is no need for a costly towing service, recharging takes within 20 minutes depending on the vehicle and the portable charger used.

FAQ - Frequently asked questions

Yes, when using an additional external charger supplied as an optional accessory. This function will be coming soon (Q4/2023).

Yes, it is possible to use solar energy with solar modules and charge the ecoPowerTrolley with it at the same time as operating it. This function will be coming soon (Q4/2023).

Yes, a total of two ecoPowerTrolley can be connected to each other and thus the capacity is increased accordingly. You can also find more technical information in this data sheet.This function will be coming soon (Q4/2023).

Yes, it is possible to change the battery. However, the battery can only be replaced by the manufacturer or licensed contractors.

Yes, the basic version of the ecoPowerTrolley comes without wheels, feet and pull-out handle. This version is particularly suitable for fixed installation in service vehicles, for example.

No. The integrated insulation monitor means that an external RCD is not necessary, even for several appliances connected at the same time.

Yes, the ecoPowerTrolley can be charged with so-called balcony power stations. The 230 V plug of the balcony power station is simply connected to one of the three ecoPowerTrolley output sockets. In this case, it is even possible to charge (via PV) and discharge at the same time.

No. Due to the certification as a UPS (when charging) and power generator without a fixed earth connection (when discharging), simultaneous charging and discharging is currently not permitted according to the standards.

Yes, absolutely. Thanks to the robust housing, which is protected against water jets and dust, the ecoPowerTrolley is designed for harsh conditions. The large solid rubber wheels, the crane eyes and the high performance in a small size make the ecoPowerTrolley the ideal companion on the construction site.

The ecoPowerTrolley is prepared for an optional GPS & 4G module. This allows the most important parameters to be located and read out via an online platform. This option will be offered by ecovolta if there is greater demand.
