Vincent from Colts Neck, NJ has been a Green Sun Energy Services client since February of 2020. A Generac Protector rated 45 kW went in that April, running on natural gas behind a 300-amp automatic transfer switch. The load survey put 8,000 square feet of living space behind it. This is a different class of machine from the air-cooled units on most of these pages: the Protector is liquid-cooled, like a car engine, which is what lets it hold that output for days rather than hours.

Standby generator questions from Colts Neck homeowners
What should a Colts Neck homeowner look for in a generator installer?
A contractor who can design, permit, install, commission, maintain and repair the whole system rather than one who sells the machine. That means generator sizing and transfer equipment, disconnect and shutdown requirements, grounding and bonding, the manufacturer's own installation requirements, gas or propane capacity and pressure, the model-specific clearances, the municipal zoning setbacks, windows and vents and carbon-monoxide entry points, flood requirements where they apply, permits and inspections, utility coordination, load management, commissioning, warranty registration, monitoring and long-term service. The lowest proposal is not necessarily the lowest cost over the life of the system.
Can a fence be put around the generator?
Potentially, but a fence cannot encroach on the required airflow, exhaust and service clearances. A removable screening panel suits some installations, though technicians still need room to open the machine and work on it safely. Local zoning may separately require or regulate screening.
Does a generator produce less on natural gas than on propane?
Some models do have a lower rated maximum output on natural gas than on propane -- a current 22 kW machine is rated 22 kW on LP and 21 kW on natural gas. Other models carry their own ratings, so the model-specific specification sheet is what settles it rather than a general rule.
