7. 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 mechanical 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.
