8. FAQS
(1) How does the wind turbine control power and RPM in high winds?
Your wind turbine’s operation will be halted to reduce the risk of damage due
to overcharge and over-spin of the rotor blades. This process of braking is
handled internally through your MPPT charge controller.
(2) What is the maximum wind speed the wind turbine will survive and do I
need to take it down in a storm?
Your wind turbine is designed to operate in most climatic conditions. Should
you expect or experience winds of 30 mph (13 m/s) upwards, please utilize
your manual stop switch to protect from any over spin. When the wind is
getting stronger up to 112 mph (50 m/s) it is necessary to lay down the Tower
to offer further protection.
(3) How long will the bearings or other wearing parts last?
According to engineer calculations, the bearings should have a 10-year
life span in 6 m/s average wind speed sites. Bearing life will vary from
one application to another; however, you should expect at least a 5-year
performance in adverse conditions and 10-year in normal conditions.
(4) Can the wind turbine be connected in reverse-polarity to the battery
without causing any damage?
Reverse polarity will cause damage to both your MPPT controller and battery
if not quickly remedied. Always double check any wiring to reduce the risk of
reverse polarity. Your turbine is equipped with polarity protection to reduce
the risk of damage, but it is still possible to degrade your wiring and cause
damage to the overall system.
(5) Will it hurt my wind turbine to short-circuit the output?
No, the wind turbine is designed to be short-circuited as a normal shutdown
procedure by a fuse. The function of the stop switch is to disconnect the
turbine from the batteries as well as short-circuit the output of the turbine.
