The complete system
Everything Delta installs — not just a generator.
A standby system is four parts working together. Delta sizes, installs, permits, and monitors all of it.
Guardian standby
An air-cooled Generac Guardian, sized to your home, in a corrosion-resistant aluminum RhinoCoat enclosure built to live outside for years.
Automatic transfer switch
The brain of the system. It senses an outage, safely disconnects the grid, and moves your circuits to generator power — then switches back when utility returns.
Free Mobile Link Wi-Fi
Check your generator’s status, run history, and maintenance alerts from your phone — included free on every Guardian we install.
Natural gas or propane
Tied into your existing gas line or propane tank so it runs for days — no refueling, no gas cans, no extension cords.

Every Guardian we install: aluminum RhinoCoat enclosure · free Mobile Link Wi-Fi monitoring · 5-year limited warranty · runs on natural gas or propane. 14 kW and 18 kW models are also available — your sizing confirms the right one.
Liquid-Cooled Standby
More power for big homes & light commercial.
When a large home, estate, or small business needs more than an air-cooled unit can deliver, Generac’s liquid-cooled standby generators step up — a liquid-cooled engine built for higher output and extended run time, installed and serviced by Delta.
Solar & Battery Storage
Store power. Use it on your terms.
A Generac PWRcell battery system stores energy — from solar or the grid — so your home keeps running through an outage and you can lean on stored power during peak-rate hours. Pair it with a Generac standby generator for layered, all-day backup.
EV Charging
Fuel your car at home.
A Generac EV charger brings fast, safe Level 2 charging to your garage or driveway — installed by Delta’s licensed electricians and ready to work alongside your home’s backup power.
ecobee Smart Thermostat
Comfort that pays attention.
ecobee — a Generac company — learns your routine, balances comfort room by room with remote sensors, and trims wasted energy. One more piece of a connected, efficient Delta home.
How it works
Automatic backup power, in four steps.
Utility power is lost
A storm hits or the grid fails — the electricity you depend on is suddenly gone.
Your system detects it
Within seconds, your Generac senses the outage and prepares to restore power.
The generator starts
It starts on its own and, through the automatic transfer switch, powers your home’s circuits — no cords, no manual steps.
Power is restored
Your home is back up in seconds and runs on natural gas or propane for days. When the grid returns, it switches back to standby.
