Our AC Dock 3000 is a sustainable alternative compared to a conventional diesel generator.

The green generator offers you maximum CO2 avoidance through 2nd life electric vehicle battery upcycling technology. Over its lifetime, 10t CO2 emissions can be avoided in comparison to a 3 kVA generator.

This solution consists of the AC Dock 3000, as well as two betterPacks 2000, made from upcycled electric car batteries. The batteries can be charged via the grid or PV panels. Additional optimizing through green power and online data evaluation is also possible.

No matter what application you would like to use green power for, the AC Dock 3000 is adjustable to your individual needs thanks to its modularity, mobility, quietness and zero emissions. Ideal for indoor, as well as outdoor applications.
