Kendis from Manasquan, NJ has been a Green Sun Energy Services client since September of 2019. The generator was commissioned that December: a Generac Guardian rated 19.5 kW on natural gas, feeding two 150-amp service-entrance switches – 300 amps of transfer capacity in total – with three smart management modules. Two switches rather than one is the arrangement a house with two electrical services needs, and it is the only installation of its kind on the site. The load calculation asked for 20 kW across 4,579 square feet, so the machine sits just below the figure and the three modules make up the difference by staggering what starts when. Annual maintenance, a ten-year extended parts-and-labor warranty and monitoring we manage all sit behind it.

Standby generator questions from Manasquan homeowners
Why do outages last longer on some Manasquan 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.
Does a permanently installed generator need a disconnect?
Yes. Permanently installed generators fall under the disconnecting-means requirements of the National Electrical Code's generator article, and the equipment and electrical design have to satisfy those requirements alongside the machine's own listing and instructions.
How quickly does it take over?
The automatic start sequence normally begins within seconds of the controller deciding that utility power has failed or fallen outside acceptable limits. There is a deliberate short delay so that a momentary flicker does not trigger a full start and transfer. Exact timing depends on the controller, the transfer switch and the configuration.
