Lillian from Manalapan, NJ has been a Green Sun Energy Services client since October of 2021. The generator was commissioned in May of 2022: a Generac Guardian rated 17 kW on natural gas, on a 200-amp whole-house transfer switch. The load calculation asked for 13 kW across the 1,800 square foot house, so the machine sits well above the requirement – which on a smaller house is worth doing rather than sizing to the minimum, because a generator running near its limit for three days ages faster than one that never has to try. Two refrigerators, a separate freezer, a sump pump, a washer, a gas dryer and a dishwasher all keep running. The generator is supported by annual maintenance, an extended parts-and-labor warranty, and monitoring we manage.

Standby generator questions from Manalapan homeowners
Can the generator be connected to any nearby gas pipe?
No. The branch supplying the generator has to be sized for the flow and pressure the machine needs. A pipe that happens to be close by may be too small, or may already be carrying too much load. Undersized piping shows up as poor starting, unstable running, reduced output or a generator that shuts down under load.
What happens when the utility power comes back?
The system detects the return of acceptable utility power and transfers the house back automatically. The generator then runs through a programmed cool-down before shutting off and returning to standby. Nobody has to switch anything back by hand.
What should a Manalapan 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.
