Automatic Transfer Switches
Every standby generator we install is paired with a Briggs & Stratton automatic transfer switch (ATS). The ATS constantly monitors utility power; the moment an outage is detected, it starts your generator and switches your home’s circuits over — automatically, in seconds. When utility power returns, it switches back and shuts the generator down.
- 100 Amp — typical for older homes with 100-amp electrical service
- 150 Amp — for upgraded service panels
- 200 Amp — the most common choice for newer homes with 200-amp service
- Dual 200 / 400 Amp — for larger homes and small businesses with split distribution

Symphony® Choice Power Management
Want whole-house coverage without oversizing your generator? Briggs & Stratton’s Symphony® Choice Power Management intelligently prioritizes your home’s biggest loads, so a smaller (and more affordable) generator can safely power your whole home:
- Low Voltage Module — manages thermostat-controlled loads like air conditioners; indoor installation, no extra wiring, 3-year limited warranty.
- Low Voltage Dual Module — controls two thermostat-based systems at once (e.g., dual AC units).
- 50 Amp Module — manages standard 120/240V appliances such as stoves, ovens, and electric heat.
Power management reduces fuel consumption and can significantly lower your total installed cost. Ask us whether a smaller generator plus Symphony Choice is the smarter fit for your home.
Generator Repair & Service — All Briggs & Stratton Models
We don’t just install — GSHA Services repairs and maintains Briggs & Stratton generators of every generation, including discontinued models. Whether your generator won’t start, fails its weekly self-test, shows an error code, or is due for annual maintenance, our technicians diagnose and fix it.
Own an older Fortress-series generator? The Briggs & Stratton Fortress line (10kW, 12kW, 17kW, 20kW, 25kW, and 30kW) has been discontinued and replaced by the PowerProtect™ DX series. We still service and repair Fortress units — and when parts availability or repair cost makes replacement the smarter choice, we’ll show you the equivalent DX model.

What Does Installation Cost?
A completely installed 20kW-class standby generator system typically starts around $6,000, with complex installations exceeding $15,000. Your final price depends on the distance from your gas meter, the location of your electrical panel, generator size, and site conditions. Our quotes include the generator, automatic transfer switch, labor, and materials (municipal permit fees are billed separately).

Frequently Asked Questions
How fast does a standby generator turn on after an outage?
Within seconds. The automatic transfer switch detects the outage, starts the generator, and restores power without you lifting a finger — even if you’re away from home.
What fuel do Briggs & Stratton DX generators use?
Every DX model runs on natural gas or liquid propane, with NGMax™ technology delivering full-rated power on natural gas for most models. We’ll configure the unit for your home’s fuel supply during installation.
What size generator do I need?
It depends on your home’s square footage, HVAC equipment, and which circuits you want backed up. A 13kW unit covers essentials; 22–26kW units handle whole-house loads including central air. Our free consultation includes a load calculation so you don’t overpay for capacity you don’t need.
How loud are they?
PowerProtect DX generators run at 65–69 dB(A) — about the level of a normal conversation or a quiet dishwasher, and quieter still during the brief 16-second Eco-Cise™ weekly self-test.
Is the 10-year warranty really included?
Yes. PowerProtect DX models include Briggs & Stratton’s 10-year comprehensive warranty covering parts, labor, and service — no out-of-pocket costs.
My Briggs & Stratton Fortress generator needs repair — do you still service it?
Yes. Although the Fortress series has been discontinued and replaced by the PowerProtect DX line, we repair and maintain Fortress 10kW–30kW units. If a repair no longer makes economic sense, we’ll quote a DX replacement. See our generator repair service.
