REST ASSURED THAT THE KESTREL WILL BE SERIOUSLY DAMAGED FROM POLARITY REVERSAL.
OVERCHARGING OF THE BATTERY CAN OCCUR WITH NO FITTED CHARGE CONTROLLER. IT IS
UNWISE TO DISCONTINUE CHARGING BY DISCONNECTING THE e300
iiii
FROM THE BATTERY.
THE TURBINE THEN HAS NO LOAD WHATSOEVER AND CAN REACH VERY HIGH ROTATIONAL
SPEEDS.
Uncontrolled output voltage can reach LETHAL values.
IF THE e300
iiii
IS DISCONNECTED FOR ANY REASON, SHORT THE GENERATOR OUTPUT WIRES.
THIS WILL LOAD THE GENERATOR AND MINIMISE ROTATION.
DO NOT ALLOW THE e300
iiii
TO OPERATE WITH DAMAGED BLADES OR TAIL. DAMAGE TO
THE BLADES WILL CAUSE VIBRATION THAT CAN INCREASE TO DESTRUCTIVE LEVELS.
DO NOT ALLOW THE e300
iiii
TO OPERATE WITH ANY SIGN OF UNBALANCE. ANY REPETITIVE
SWINGING OF THE TAIL INDICATES THAT THE MACHINE IS UNBALANCED.
Q There is wind but the e300
iiii
does not rotate or only rotates very slowly.
A
The e300
iiii
output is shorted. There is an electrical short elsewhere in the system. The blades
are fitted the wrong way round. The e300
iiii
is restricted from swinging 360 degrees into the
wind. The charge controller is defective. Other connected equipment is defective. (Disconnect
the e300
iiii
from the equipment and check that the blades rotate easily). There is a short
within the turbine generator. In very light wind, the e300
iiii
may well not rotate. This is quite
normal as there is no useful power in such a light wind and bearing life is greatly extended.
On older machines, check the generator bearings.
Q
The e300
iiii
is rocking from one side to the other at low speed but appears to run smoothly at
higher speeds.
A
The blade rotor assembly is unbalanced. Remove the rotor and check for damaged blades.
Rebalance the rotor if possible or fit a new blade set.
Q
The e300
iiii
is vibrating or noisy.
A
Check all fasteners on the unit, in particular the blade assembly. Vibration or noise can only
be caused by the imbalance of damaged blades. Check for bearing wear on older
machines.
Q Can the e300
iiii
be left running and disconnected?
A Theoretically yes, but high voltages may be produced. Always short the output wires when
the e300
iiii
is disconnected from the regulator.
Q What should be done in storm conditions?
A Never approach the e300
iiii
during strong wind conditions. The e300
iiii
has been tested up to
winds of 160km/h and is designed to survive such conditions. It is acceptable to lower the
turbine for predicted extreme weather conditions simply for peace of mind.
