what is it?
We are a startup providing energy storage systems for industries. The nuvola device has been designed in the power electronics labs of the Arts&Métiers University in Lille, Francia.
To companies interested, we propose a free test drive.
solar self consumption
In many countries, injecting solar energy in the grid is no more economically rewarding.
A new business model is born: self consume, onsite, the photovoltaic energy produced on the roof.
economy + ecology
In some european countries (Italy, Switzerland, Germany...) photovoltaic energy is twice cheaper than if purchased from the grid!
Thus the interest to self-consume most of it.
how to best self-consume?
Storing energy is a solution (like for example Tesla's powerwall); but it requires a high investment and a long payback time.
However, for small and medium enterprises, a simpler and more economical solution exists!
One day, speaking with a forklift driver, I realised that often these machines are operational only a few hours a day...
...But below these vehicles sit very large batteries: for example one typical forklift battery could power up a floor of offices for an hour!
the new paradigm
...the rest of the time, these "batteries on wheels" are unused - and worse, they stay at low states of charge, which makes them age fast.
then why not using these batteries as solar energy storage?
in concrete terms...
For a small enterprise with photovoltaics on the roof, and owner of a forklift, it would be enough to have an "intelligent plug" that decides whether to charge or discharge the battery, depending on an algorithm which optimises solar self consumption...
...and that's what we did!
After several laboratory tests, and a patent...
...the device is ready for field tests in industrial context.
A free trial is proposed, lasting from 1/2 day to a few weeks, to show the potential of the solution.
Just connect it to a 3-phase plug: there is no need to intervene neither to the main low voltage board, nor the PV installation.
what is needed for the test drive:
The test will allow us to:
and for you...
The charger is tested and verified as per national regulations, and we guarantee the state of health of your battery for 30 days after the trial.
