Standby Generator Service

Green Sun Energy Services installed a Generac standby generator at a home in Ocean Township for a client since June of 2024, commissioned in October. This installation sits closer to its calculated limit than most. The house runs to 3,158 square feet and carries an unusually heavy electrical load: an electric cooktop and a double electric oven, three refrigerators, two sump pumps, a dishwasher, a microwave, and a washer with a gas dryer. Worked through under the National Electrical Code, that came to a minimum of 21 kW, and the installed machine delivers exactly 21 kW on natural gas. There

Green Sun Energy Services installed a Generac standby generator at a home in Far Hills for a client since June of 2024, commissioned at the end of July. This house is a useful illustration of why the load survey matters more than the floor area. At 2,012 square feet it is one of the smaller homes we have fitted a generator to, yet it needed a larger machine than houses half again its size, because the dryer and the range and oven are all electric rather than gas. Electric cooking and electric laundry are among the heaviest draws in any

Green Sun Energy Services installed a Generac standby generator at a home in Red Bank for a client since June of 2024, commissioned at the end of August. The job made use of what was already in place: control and power wiring had been run into the attic previously, so rather than pull new cable through the house the existing 18/7 control wire and aluminum feeders were kept and extended by about seventy feet to reach the generator position. Less disruption, and less of the cost going into work nobody ever sees. The 2,500 square foot house carries a double

Green Sun Energy Services installed a Generac standby generator at a home in Atlantic Highlands for a client since June of 2024, with the machine commissioned the following month. This one runs the whole house rather than a selected group of circuits: the automatic transfer switch is rated at 200 amps and carries the full service, so nothing has to be chosen in advance and nothing is left off during an outage. Sizing came from the load survey rather than the square footage. The 2,650 square foot house has a gas dryer and washer, two refrigerators, a freezer, a dishwasher,

Martin from Fair Haven, NJ has been a Green Sun Energy Services client since April of 2026. We installed a 22 kW Generac in June, making 21 kW on the natural gas it runs on here, switching the whole house through a 200-amp service-entrance transfer switch with surge protection built in. At 3,800 square feet this is a large house, and the code calculation put the minimum at 16 kW, so the machine that went in carries a comfortable margin above what the arithmetic required. Two refrigerators and a sump pump are the loads that decide whether an outage is

Ismael from Tinton Falls, NJ has been a Green Sun Energy Services client since April of 2026. We installed a 26 kW Generac at the end of May, making 24 kW on natural gas and switching the whole 3,200 square foot house through a 200-amp service-entrance transfer switch with surge protection built in. The code calculation put the minimum at 15 kW, so this is considerably more machine than the arithmetic demanded, and the margin is the point: a motor draws several times its running current in the instant it starts, and a generator sized exactly to the minimum is

Ken from Brick, NJ has been a Green Sun Energy Services client since March of 2026. We installed a 14 kW Generac in June, running on natural gas and switching the whole house through a 100-amp service-rated transfer switch. The well pump is what makes the sizing matter here, because a house on a well loses its water altogether when the power goes rather than only its lights, and that is the difference between an inconvenience and having to leave. Two refrigerators and a freezer add to what the machine has to hold, and the code calculation put the minimum

Oded from Leonardo, NJ has been a Green Sun Energy Services client since May of 2026. We installed a Generac in June, rated 24 kW on propane and 22.5 kW on the natural gas it runs on here, standing outdoors beside the meter. The two heat pumps are what set the size: a house heated and cooled electrically loses its heat in an outage rather than just its lights, and heat pumps pull hard at the moment they start. With two refrigerators alongside them the code calculation put the minimum at 21 kW, and load management modules keep the largest

Robert from Fair Haven, NJ has been a Green Sun Energy Services client since July of 2019. We installed a 16 kW Generac Guardian that October, running on natural gas and sited outdoors beside the meter, switching the whole house through a 200-amp service disconnect with automatic load shedding. The sizing came from the load survey rather than the floor area alone: 3,000 square feet is only part of it, and the well pump and sump pump are the reason the number matters, since a house on a well has no water at all without power and a sump that
