Q. Do I need a charge controller, stop-switch, and resistor?
A. Installation of a charge controller, stop-switch, and power resistor is mandatory to
protect your batteries, as well as the turbine. A charge controller and diversion load
power resistor will safely dissipate excess power to avoid overcharging when the
batteries are completely full. A stop switch is mandatory and will allow you to safely
perform maintenance near or around your unit.
The use of a Superwind 48V SRC marine charge controller enables your system to be
completely autonomous and helps ensure a full state of charge and long battery life.
Q. What size wire do I run to the Superwind and the charge controller?
A. This Superwind manual specifies wire sizing for various distances (the wire run). The
proper wire size is important to optimize charging and eliminate the risk of fire. Refer
to the wiring specifications provided in this manual. Please do not hesitate to contact
us for recommendations regarding your specific project.
Q. Can I hook up to my hot water tank and avoid overcharging?
A. No. The internal electrical components in hot water tanks will not withstand
overcharging and will fail. This will, in turn, shed power to your batteries, which can be
very dangerous. Always install the provided Superwind power resistor for use as the
system diversion load.
13.3 Operation
Q. Can the Superwind be left ON while unattended?
A. The Superwind 350/48V kit allows for safe autonomous operation 24/7 when installed
properly with the SRC marine charge controller and diversion load resistor (included in
the kit).
The Superwind 350 is a commercial turbine designed for off-grid use in remote areas.
When installed properly, it is maintenance-free and can be left unattended. While you
can always use the safety-stop switch to temporarily shut down the unit, it is not
required.
Q. Do I need to tie down the Superwind in high winds or storms?
A. No. Tying down a Superwind 350/48V blade or vane can actually damage the unit.
Instead, utilize the safety-stop switch to enable the dynamic (magnetic) brake. The
Superwind 350/48V is designed to operate in wind conditions nearing hurricane force
speeds. In most circumstances, the unit can be left on without endangering the turbine
or the batteries.
Q. How long do the bearings last?
A. The Superwind 350/48V ‘auto-feathers’ during high wind conditions, which prevents
over speed of the turbine and lessens the wear on the bearings. This technology
allows Superwind units to have a long life – many have been in the field for over a
decade and are still going strong.
