and Uses
The e300
iiii
is suitable for electrical power generation on various installations that include battery
charging, water delivery and grid tie applications. Each application requires specific additional
electrical equipment. Consult the manuals supplied with this equipment.

Any wind turbine produces uncontrolled power that varies with incident wind speed. The open
circuit generator voltage is directly proportional to generator speed (rpm). Some form of
regulator must control this “raw power”. A battery charging regulator is often referred to as a
charge controller.
A charge controller is required for the Kestrel to charge a battery. Kestrel can supply a standard
charge controller for the e300
iiii
. A suitable diversion resistor is available from Kestrel.
An inverter can be connected to the battery and is used to convert the battery dc power to ac
power. An inverter therefore allows the use of standard electrical equipment that works on ac
voltage.

The 200Vdc version of the e300
iiii
is suitable for connection to an approved Grid Tie Inverter. Grid
Tied installation is subject to local electrical codes of practice and is usually carried out by
qualified personnel. Prior approval from the local utility company must be obtained before
connection to the mains.

Voltage Limiter
Grid tied applications require a Voltage Limiter to be connected between the e300
iiii
(200Vdc
version) and the Grid Tie Inverter. Certain operating modes of the inverter allow the Kestrel output
voltage to rise beyond the limit of the inverter. The Kestrel Voltage Limiter will restrict the rise in
voltage as the inverter performs various functions. Refer to the manual provided with the Kestrel
Voltage Limiter.
