Standby Generator Service in Holmdel, NJ | 20 kW Whole-House Backup

Holmdel, NJ · Client since May 2019

Richard from Holmdel, NJ has been a Green Sun Energy Services client since May of 2019. The 20 kW standby generator at the house was installed by another company in September of 2018 — barely eight months old when Richard moved its servicing to us and took an extended parts-and-labor warranty on it. Every interval since has been done in sequence, the one-year check through to the seven-year, completed in September of 2025 with 120.1 hours on the meter and the fuel plenum clear of rust. There has also been one repair carried out under the manufacturer’s warranty. Picking up a machine while it is still nearly new is the easy version of this work: nothing to undo, and a full service history from the first year onward.

Standby generator questions from Holmdel homeowners

Why do outages last longer on some Holmdel streets than others?

Mature tree cover over overhead lines is the usual reason. Limbs coming down in wind, snow or ice take the lines with them, so heavily treed streets tend to see both more frequent outages and longer restoration times than open ones. It is one of the honest arguments for standby power rather than a portable generator.

What does a whole-house generator actually mean?

Whole-house generally means the transfer equipment serves the home's main electrical system rather than a small emergency-circuit panel. It does not promise unlimited capacity. High-demand appliances may still be prioritized or briefly shed while generator capacity is being used elsewhere.

What is a service-entrance-rated transfer switch?

One that is listed for use as service equipment when installed in the appropriate configuration. These are commonly used for whole-house systems, where the transfer switch becomes part of the home's service arrangement rather than sitting downstream of it.
