Power Take Off (PTO)
generators offer a very cost effective way to produce electrical power. It
eliminates the need of the tractor owner to maintain an additional engine. It
allows the tractor owner to utilize their tractor that is normally well
maintained and ready to run rather than a portable generator with a light duty
engine that does not want to start after it has been sitting with stale fuel,
varnished or stuck carburetor, and a dead battery. PTO generators operate from
the tractor's power take off to produce clean, reliable power. Brushless PTO
generators require no maintenance. They have a useful life many times greater
than engine generators.

|ALL Tiger Power Generators are AVR Regulated
An AVR takes in a range of voltage levels and automatically outputs a
voltage with a much narrower range of voltage levels. For example, Tiger
Power automatic voltage regulators may have an input voltage range of +10%
to -25% and convert this to a regulated voltage range of +2% to -2% of the
nominal output voltage. A vast majority of economy PTO generators use
capacitor regulation which is not nearly as stable and can be detrimental to
the electronics in your home.
Frequently Asked Questions (F.A.Q.)
Generator Sizing Calculator
#1 Who can use a
Anyone with access to a tractor equipped with a power take off.
do I power my whole breaker panel?
A Manual Transfer Switch is required to safely transfer between the PTO
generated power and the Power Company to your breaker panel. Other methods are
possible but not recommended for risk of back feeding the power grid. Each
generator has several outlets where extension cords can be plugged in directly.
size PTO do I need?
A PTO generator should be sized to power critical demands in a start-up or
"surge environment." Your load must be determined by the critical electrical
demands need to be supported when utility power is down; with a specific focus
on any equipment with electric motors.
2 Kilowatt (kW) per motor
(based on Code G motors) horse power is required to allow the PTO generator to
provide the required starting amps to start an idle electric motor.
For example: a customer that needs to support (2) 2.5 HP motors will need at
least a 10 kW PTO (5 HP x 2 = 10 kW)
If the customer's load is
all resistant load (like light bulbs), simply add the wattage of each load. For
example: a warehouse has (40) 100 Watt light bulbs, a 5000 watt electric water
heater, a 700 watt refrigerator, and a 5 watt phone system will need a 10 kW PTO
(4000 watt + 5000 watt + 700 watt + 5 watt = 9705 watts = 9.705 kW)

calculator OR go to the TigerPower website for an automatic kW and HP calculator
Horse Power (HP) tractor do I need?
The customer will need at least 2 (HP) per kW. For example, a customer needing a
10 kW PTO will need 20 PTO-HP.
Larger tractor than
required for the generator. If you only need 10 kW and own a 24 PTO-HP
tractor, you can still use a 10 kW PTO generator. You will only generate the 10
kW rating. You will have the benefit of better surge capacity and less speed
variation with the extra tractor HP.
than tractor can handle. If you only have a 24 PTO-HP tractor and
purchase a 15 kW generator, you will only generate 14 kW output. There will be a
benefit of added surge capacity and less speed variation due to the additional
mass that gives additional momentum (Flywheel effect).
#5 What does all
copper windings or all copper wiring refer to?
All copper winding and wiring refers to the same thing. It simply means that the
material used in the generator windings are made of 100% copper. Some
manufactures use copper coated aluminum to reduce cost, which expands and
contracts causing connection failures and does not conduct power as efficiently.
is TigerPower’s Digital Frequency Meter superior to other meters?
There are three main alternatives to using the “FreqMon2005”; the analog hertz
meter, the digital hertz meter and the three light displays. The analog meter
can be prone to errors from vibration and can be difficult to see in low
visibility situations. Both the analog and digital meters have no indicator to
determine what the acceptable range is for the PTO to operate safely. The three
light displays provide very limited information. It only informs the operator if
the frequency is good or bad, it cannot indicate how close the frequency is to
good or bad.
The “Freqmon2005” is an
innovative display that solves all of these problems. Its solid-state design
makes it immune to the problems caused by vibration. It is capable of displaying
11 different frequency ranges showing the operator how close they are to the
safe operating frequency. To use correctly the only thing the operator needs to
know is that green is good, yellow is marginal, and red is bad. Its five, high
visibility, LED’s make it easy to see from the tractor so the operator can
easily adjust the RPM’s to obtain the proper setting.
is class “H” Insulation?
Class H refers to the temperature rating of the insulation. Insulation is
degraded by long term exposure to high temperatures. Higher temperature class
insulation can also withstand higher temperatures without failure. Class H
insulation is rated for 180º C continuous operations without shortening
does “Tropicalized” mean?
This refers to the resin used to coat the generator windings. Tropicalized
windings are coated with a resin that protects the winding from adverse weather
conditions and salt air.
#9 What is the
difference between the many ratings?
Standby rating - The rating that is assigned to a unit to be used
as an emergency backup source. Generator will produce the rated kW for a short
amount of time. This is a very common rating of large standby power systems for
facility backup power.
- The rating at which a sudden temporary variation (surge) in current, voltage,
or frequency can occur without harming or stalling the generator. This is the
rating used by portable generator manufacturers. It can be very misleading if
you are comparing this rating to commercial duty equipment such as a TigerPower
rating - Refers to the rating that is assigned to a unit to be used as
an emergency backup source with varied load. This generator will produce
continuously at the rated kW at varied loads. This is the rating TigerPower uses
for their PTO generators.
- The rating at which the generator can operate with a constant non varying load
for an unlimited time. This is set by the manufacture and is the machines
capability to produce “x” amount of power continuously if the load doesn’t
change. This is a typical rating for large engine driven units used for peak
- The rating at which the generator can operate with a varying load for an
unlimited amount of time. (24/7/365) Used when the generator is the sole power
is an Automatic (or Electronic) Voltage Regulator (AVR) and the meaning of +/-
A generator with an AVR monitors the output voltage and automatically adjusts
the output voltage to maintain a very stable voltage. The +/- indicates the
window of accuracy. If you set the unit at 240 Volts and the regulator is +/-
2%, the voltage will be maintained between 235.2 and 244.8 volts, which are
within 2% (+/- 4.8v) of 240.
is better continuous duty rating at a higher or lower ambient temperature?
The ambient temperature refers to the temperature of the air surrounding the
unit. It is best to be able to operate at a higher ambient
temperature. Most generators are designed to operate at an ambient temperature
of 40º C.
TigerPower PTO generators be operated outdoors?
Yes they can. The TigerPower PTO is designed for “Drip-proof” operation.
Drip-proof is an industry term meaning having ventilating openings constructed
so that drops of liquid or solid particles falling on the machine at an angle of
not greater than 15 degrees from the vertical cannot enter the machine.
Sheltering the PTO unit is highly recommended for use during inclement weather.
