22 kW Generac standby generator in Colonia, NJ by Green Sun Energy Services.
Jaclyn from Colonia, NJ has been a Green Sun Energy Services client since May of 2021. The generator was commissioned in February of 2022: a Generac Guardian rated 19.5 kW on natural gas, on a 200-amp service-entrance switch with two smart management modules. The load calculation asked for 15 kW across the 3,000 square foot house, so the machine carries a comfortable margin – and two sump pumps are the reason that margin is worth having, since both will want to run in exactly the storm that takes the power down. Nine months separated the contract from the commissioning, the equipment lead times of that period rather than anything on site. Annual maintenance, an extended parts-and-labor warranty and monitoring we manage all sit behind it.

An excellent company that is organized, kind and efficient. I got my generator all set up and I couldn't be happier for the coming apocalypse! Thank you so much Green Sun Energy Services!
Green Sun Energy Services replied
Thank you, Jaclyn. The 22 kW Generac at your home in Colonia will handle a great deal more than the apocalypse, but we appreciate the readiness. Organised is the word we work hardest at, because a generator project touches gas, electrical, permits and inspections and any one of them can hold up the rest.
Standby generator questions from Colonia homeowners
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.
What should a Colonia 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.
Does the generator start on its own?
Yes. A properly installed standby generator left in AUTO is designed to start automatically when it detects an unacceptable loss of utility power. The transfer system then moves the household loads across, and when acceptable utility power returns it transfers them back and the generator runs through its programmed shutdown.
