1. What is the difference between a portable gasoline generator
and an automatic generator system?
Noise… Complete Automation ... Comfort … Safety …
Convenience … Back Feed… Run time … Preset Self
Exercise … Diagnostic Check… Otherwise, they are the
2. How does a standby generator work?
Please refer to the System Set-up
& Operation section.
3. What size standby generator do I need for my house during
a power outage?
Please refer to the Sizes/Options/Prices/Specs
4. What does a Standby Generator System typically cost?
The all inclusive, turnkey cost of automatic generators ranges from
$8,000 to $12,000 for the small systems (8-13kW), from $17,000 to
$25,000 for the medium systems (18-35kW), and from $35,000 to $55,000
for the large (whole house) systems (45-100kW), depending on the
size, manufacturer, options, site conditions, and difficulty of
installation. Please refer to Sizes/Options/Prices/Specs
section for more information.
5. What is the process for a typical installation?
Please refer to the Process, Pictures
6. Can my generator be installed inside my home?
NO! A generator has an internal combustion engine and uses gas and
oil. The exhaust from running the generator contains lethal carbon
monoxide. Therefore, a generator should always be located outdoors
in a well ventilated area.
7. How long will my generator run during an extended power
Your generator will run for as long as your fuel supply is available.
Provided the proper oil level is maintained, natural gas fueled
generators can technically run for weeks at a time, while run time
for propane gas and diesel fueled generators is usually between
2-7 days without refueling, as determined by the size of their supply
8. Is financing available?
Yes! Financing is available, up to 100% of the total cost of the
project. Please ask your sales engineer about the specific financing
programs available for your system.
9. How will I know if and why my generator has failed to
All our generators have a diagnostic center inside the generator
and on the transfer switch. The flashing light indicator panel display
will alert you if the generator has failed to start and the nature
of the problem.
10. Can I run a computer or other sensitive electronic equipment
off the generator during a power outage?
Yes, the power coming from your generator is just as safe as what
you normally have coming from your utility company. The spikes or
surges that accompany power generation are just a normal aspect
of electricity. However, you should use a good surge protector to
guard against small influxes in power when using sensitive or expensive
electronic equipment running off a wall outlet, regardless of whether
you have a generator or not.
11. Do I have to worry about “back-feed” when
the generator is running and the utility power is (or comes back)
No. All of our transfer switches are automatic and designed to keep
back-feed from occurring, much like it is not possible for you to
turn a light switch on and off at the same time.
12. What is the warranty on automatic generator systems?
The warranty on generators and switchgear is from 1-3 years or 1,500
hours, depending on the manufacturer.
13. What’s a Preventive Maintenance contract? Is it
included as part of my warranty? If not, how much does it cost?
Does it affect my warranty if I don’t chose to do it?
A preventive maintenance contract is a monthly, quarterly, semi-annual,
or annual service to check your generator’s proper operation
and readiness. It includes an oil change, operational and functional
checks of all system components, testing, minor repairs/ adjustments,
and recommendations for additional repairs and services if needed.
Our typical preventive maintenance contract is for semi-annual service
and costs between $300-500/year (for both visits).
Preventive maintenance contracts are unrelated to nor included as
part of your warranty. Warranty is offered by the manufacturer and
remains valid regardless of your decision on a preventive maintenance
How often does the oil need to be changed and what type of oil
should be used?
Synthetic oil is the best choice when an oil change is needed.
An oil change is recommended every 50 hours and the oil filter
every 100 hours. The hour meter located on the control panel inside
the generator will help you gauge when maintenance is needed.

service, warranty, or preventive maintenance?
