Generac 20 kW Standby Generator in Holmdel, NJ | Dual Transfer Switches, 4,400 Sq. Ft.

Holmdel, NJ · Client since March 2013

Jeff from Holmdel, NJ has been a Green Sun Energy Services client since March of 2013. He signed in early March and the generator was commissioned in late June, and it is the most involved residential installation in our records: a 20 kW Generac behind two 200-amp service-rated transfer switches with six load management modules, covering 4,400 square feet with two refrigerators, two freezers, a dishwasher and the laundry. A house with two service panels needs two switches. Holmdel is in Monmouth County.

Standby generator questions from Holmdel 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 size standby generator does a Holmdel home need?

The correct size is decided by the electrical loads the generator is expected to run, not by the square footage of the house. Central air, heat pumps, electric heat, well and sump pumps, refrigerators and freezers, electric ranges and dryers, pool equipment and EV chargers all count. Where a load is connected automatically, the generator either has the capacity for it or an approved load-management system controls it.

How often should a standby generator be serviced?

Maintenance follows the schedule for the exact model and its operating hours. For current air-cooled units that means an annual inspection plus scheduled work at hour-and-year intervals. Extended running during a long outage can bring the next service forward.
