Off-grid energy cubes from Stäubli provide 230 V AC output


Available from Stäubli Electrical Connectors is the Power-Blox 200, a new
innovative energy storage system that can deliver 230 V AC at powers from
200 W up to the kilowatt range. The modular system uses swarm technology,
and can serve as a “portable socket” to meet off-grid energy requirements.

The standalone energy cubes house an integrated battery and can be stacked
and plugged together to automatically configure a private mini-grid. With a
decentralised architecture and no central control, additional units can
easily be added as power requirements increase.

The Power-Blox 200 system is self-learning and self-configuring, and
regulates power production, storage and distribution within the grid
intelligently and autonomously. It is infinitely scalable, requiring no
configuration, engineering or maintenance, and different energy sources such
as solar power and wind energy can be easily combined.

One Power-Blox 200 cube, with its 100 Ah deep cycle solar battery and
supplied by a 200 W solar module, is designed to run a small fridge, a
television, some LED lights, a mobile phone charger and a laptop computer.

Although designed for off-grid situations, the system can also be used as
backup power to bridge power cuts where public grids are unreliable.
Applications include the supply of mobile or temporary installations for aid
organisations, rural electrification in remote areas and military
installations.

Stäubli acquired a stake in the award-winning Power-Blox start-up in 2017,
and the two companies have signed a strategic cooperation agreement.

“Combined with our market-leading photovoltaic connector systems, Power-Blox
with its swarm technology will open up completely new applications for
energy storage systems,” said Selwyn Corns, managing director of Stäubli
Electrical Connectors UK.
