AT YOUR SIDE
FOR A BETTER FUTURE

January 21, 2013 © CGroup Srl [CGroup Srl confidential]

CGroup Srl, a start-up engineering and manufacturing company based in Italy, has
grown out of the venturing of engineers and international market developers with an
experience in renewable mobile energy, expanding through dedicated partners in
various countries and continents.

About us

Our aim is to provide efficient but affordable solutions for consumers and
small to medium size commercial applications in remote areas.

To receive or create energy in remote areas has always been a logistically
difficult and a cost intensive task.
Fuel generators have been the only solution up to now, with their well known
advantages, but also with great disadvantages:

Instant energy at any moment of the day or
night
Low cost of unit
Independence from environmental conditions
Reduced dimensions

Dependence from fuel (logistics )
Costly maintenance
Negative impact on the environnement (noise,
fumes)
Overproduction of energy
No energy storage capacities

Actual Energy Production

Our commitment is to find a clean and environmental friendly alternative
without compromising efficiency at the same time be able to guarantee a
constant energy output.

Renewable Sources
Independent
Free Energy
Hi-Tech
Mobile

We Offer…

The most efficient alternative to fuel generators are our
Mobile Hybrid Generators (MHG)
combining Photovoltaic and the Vertical Axis Wind Turbines (VAWT),
united in a compact, foldable, mobile plug-n-play unit,
which includes the modular energy storage.

sources. The monitoring can be effectuated directly or via remote control (WiFi).

Inverter MGH

Example situation with MGH Hybrid 3000
Weather conditions:
Case 1: High Sun Radiation
• No Grid connection (for backup) Wind ~ 4-7 ms
• No Appliances
• All energy produced by VAWT and PV
recharges the batteries only.

Inverter

Grid 0 KW
(backup only) Battery pack
Appliances Min. 3.7 Kw/h
0 Kw/h Max.7.4 Kw/h


Weather conditions:
• Appliances require 1 Kw/h
• The energy produced by PV goes to appliances,
rest goes to batteries
• VAWT recharges the batteries only.

Inverter

Grid 0 KW
1 Kw/h Max.7.4 Kw/h


Weather conditions:
• Appliances require 2.6 Kw/h
• The energy produced by PV goes to appliances
• The energy produced by VAWT goes to appliances
• Batteries are full and on stand-by

Inverter

Grid 0 KW

VAWT

Our partner company S&H has engineered and built a unique and personalized
inverter that guarantees an exact administration of the VAWT according to the
application (Grid Connected or Stand-Alone), subject to irregular wind conditions.
The monitoring can be effectuated directly or via remote control (WiFi).

Inverter VAWT

Each situation needs a solution adapted to the circumstances and the
environment, this is where our modular systems are ahead of other
products, as the standard product can be engineered and manufactured
according to each individual case.

Modular Systems

Some case studies…


Our R&D is developing new technologies in order to optimize the
space required to create and store energy in a safe and affordable
manner.

R&D

Our partners will have the advantage to be on the frontline of these new
technologies and be ahead on the market against competitors

We will be glad to discuss with you the different
possibilities to become a distributor or
manufacturing partner in your area.
