Michael from Colonia, NJ has been a Green Sun Energy Services client since February of 2022. The generator was commissioned that May: a Generac Guardian rated 17 kW on natural gas, outdoors beside the meter, with a 200-amp service-entrance switch, a smart management module and surge protection. The load calculation asked for 14 kW across 1,508 square feet, with an electric dryer among the loads – the item that most often pushes a small house past what its size would suggest, since an electric dryer draws roughly five times what a gas one does. The generator is supported by annual maintenance, a seven-year extended parts-and-labor warranty, and monitoring we manage.

Standby generator questions from Colonia homeowners
How close to the house can a generator sit in Colonia?
For the air-cooled models covered by the manufacturer's listed installation guidance, the rear of the generator can be as close as eighteen inches to a qualifying structure when every condition of that listing is met. That eighteen inches is a tested installation dimension, not a zoning setback, and a municipality can require more.
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.
Does a 200-amp service need a 200-amp transfer switch?
A transfer switch installed in the service path has to be rated appropriately for the service and the configuration. A 200-amp service commonly uses a 200-amp service-rated switch, but the actual design is confirmed by the electrician rather than assumed from the service size.
