No weak links and the highest quality

Completely tailored energy supply systems to your wishes and requirements.
You can choose from the diversity of components so you can put together or extend the energy system in your vehicle. We do more for you than just deliver products.  We are there for you from the first idea up to commissioning and we will think with you through the whole process.




The hard of your system.

Your own power station for continuous power

Solar charge regulator

with integrated MPPT offers a far higher yield from solar power for charging your batteries.

Battery charger

guarantees fast and complete charging multiple battery banks simultaneously thanks to its combined functionality.

Sine wave inverter

allows you to easily convert the voltage of your 12 V or 24 V battery to 230V/50Hz or 120V/60Hz, so you enjoy all the comforts of power grid wherever you choose to go.

The new standard in power systems

This compact inverter/ charger combination with a smart transfer system, highly efficient MPPT solar charge regulator and separate second charger (12/24V) is all enclosed within a robust unit that is easy to install.

The compact unit with advanced electronics offers a solar input, a generator input, and a parallel connection, all with very quiet operation. Meanwhile the commercial and industrial sectors benefit from having more power to hand along with the option for three phase operation. The Mass Combi Ultra is available in a series of models, with capacities from 3000 Watt to 7000 Watt. This product is a great leap forward that raises the bar and sets new industry standards.

One touch, full control.

Digital control & monitoring network simplifies installation of electrical systems through the replacement of complicated, cumbersome wiring to switch and fuse panels, with state-of-the-art, robust interfaces and light NMEA 2000 network cable. It also provides a sophisticated solution via the automation of complicated control and monitoring issues associated with today’s onboard systems.

Hugely powerful.
Enormously light.

Lithium ion batteries have a high energy density and are perfect for cyclic applications. They offer savings of up to 70% in volume and weight compared to traditional lead-acid batteries, with three times as many charging cycles (2000 full cycles).

The smartest way to charge batteries.

Lightweight and quiet!

The Fuel Cell charges the on-board battery fully automatically. The integrated charge controller permanently monitors the charge level of the battery. If necessary, the Fuel Cell starts automatically and switches off again once the battery is charged. This gives you more than permanently fully charged power reserves. Your batteries will also last a lot longer because constant recharging protects them against a damaging exhaustive discharge.
