When homeowners first explore backup power solutions, they’re often surprised by the total cost of a whole home standby generator system – especially the installation. “Why is it so expensive?” is a question we hear often at Power Source Electrical. The reality is the generator itself is just one part of a much larger picture. Installation involves a wide range of professional services, equipment, and expertise – all of which are essential for a safe, reliable, and code-compliant system.
As a Generac Power Pro Premier Dealer proudly serving the Charlotte, NC metro area, we’ve installed hundreds of standby generators and know exactly what goes into making your system ready for any outage. Here’s what’s typically included in a whole home standby generator estimate—and why it’s worth every penny.
1. The Generator Itself
At the core of your estimate is the generator unit. The price varies depending on the size (measured in kilowatts), brand, and features such as Wi-Fi connectivity, remote monitoring, or load management capabilities. Larger homes or higher power demands require more powerful (and more expensive) units.
2. Automatic Transfer Switch (ATS)
The ATS is a critical component that automatically detects a power outage and switches your home from utility power to generator power in seconds. This switch must be correctly sized for your electrical panel and properly integrated into your home’s system – something we handle start to finish.
3. Professional Installation by Licensed Experts
This is where many homeowners see a jump in cost—and for good reason. Installing a standby generator isn’t a plug-and-play job. It requires:
- Licensed Electrical Work: Our certified electricians will run wiring, conduit, install the ATS, and connect your generator to your service panel – all in compliance with local and national codes.
- Fuel Line Installation: Whether you’re using natural gas or propane, safe and proper fuel line installation is essential. This often involves licensed plumbers or gas fitters.
- Permits & Inspections: We pull all required permits and coordinate with your local municipality to ensure the system meets code and passes inspection.
- Site Preparation: Your generator needs a level, stable base – often a concrete pad or gravel bed. We handle excavation and prep as needed.
- Startup & Testing: Once installed, we conduct a full system test to confirm everything is working properly and walk you through how to operate and maintain your system.
4. Materials & Supplies
Your estimate also includes all necessary materials: electrical conduit, copper wiring, weatherproof boxes, fuel piping, shut-off valves, mounting hardware, and more. These materials add up – especially for longer runs or more complex installations.
5. Complete Installation by One Trusted Team
At Power Source Electrical, we don’t subcontract the core parts of your generator installation—we are the licensed electricians, gas line professionals, and delivery crew. That means you’re working with one experienced in-house team from start to finish.
We also take care of the entire permit and inspection process, coordinating with your local municipality to ensure every step of the project meets or exceeds code requirements. By handling everything under one roof, we eliminate the delays, miscommunication, and quality concerns that often come with juggling multiple contractors.
6. Optional Add-ons & Upgrades
Depending on your home and needs, you may also see optional items in your estimate, such as:
- Wireless remote monitoring
- Larger propane tanks
- Load-shedding modules for optimized power use
We’ll explain these options and whether they’re necessary based on your unique situation.
