systems This 30 amp shunt
charge controller
provides a versatile and
cost effective solution
for small scale battery
based systems using the
Wren micro turbine as a
power input. Samray have
taken well proven and
trusted PV charge
controller technology and
adapted it for use with
the Wren micro turbine
range.Thanks to the
unique design of the
permanent magnet
alternators used on the
Wren it is possible to
use shunt regulation to
prevent the turbine from
overcharging the
batteries without the
need for dump loads. The
heart of the controller
is based around a
microprocessor control
providing a selection of
different charging cycles
using Pulse Width
Modulation PWM. The
controller also features
a self-learning algorithm
to provide accurate
state-of-charge SOC
metering of the battery -
The best insurance for a
long battery lifetime.
The controller also
features a load
disconnect facility to
prevent the battery from
becoming discharged too
deeply and therefore
further helps protect
your battery bank. All of
these features are packed
into a compact anodised
aluminium enclosure
requiring a minimal
mounting footprint. This
allows hassle free
connection and operation
of the controller and
Wren micro turbine.The
shunt controller is
available for 12V systems
Order Code N08GW and for
24V systems Order Code

50W Telescopic Vertical Axis
Wind Turbine Vertical
WindTurbine

Ideal for motor homes
camping marine and
outdoor use Compact
design with no spinning
blades No mounting
hardware required Not
sensitive to wind
direction Effective with
wind speed of 8 - 10ms
Includes 2m cables with
alligator clips Does not
need a separate charge
controller Conventional
wind generators have the
disadvantage that they
occupy a lot of space
with their spinning
blades and large poles.
This vertical axis
generator solves the
problem this by taking up
much less space. It can
be mounted on a boat
mobile home caravan or
small building. It is
also more suitable for
areas where the wind
direction changes as they
dont need to be pointed
in the wind direction to
work. The telescopic
design means you can fold
the generator to half its
length when not in use or
when there are high wind
speeds and an LED display
give you a readout of
output voltage so you
know when its working
effectively.Cables
mounting bars and a
strong magnetic base are
included so this is a
complete portable wind
generator solution for
camping boating fishing
etc.There is no need to
use a charge controller
when charging the
battery. The battery can
be connected directly to
the battery terminal of
the Wind generator for
charging. When the
battery is fully charged
the generator will
automatically cut off the
power to battery and the
display will go out.
