The power goes out. It happens in Scottsdale more often than most people expect — a monsoon rolls through the Valley, a transformer blows, or the grid simply buckles under a record-breaking Arizona summer heat demand. For most homeowners, a blackout is an inconvenience. But for a family running medical equipment, a professional working from home, a restaurant owner mid-dinner service, or a dental office mid-procedure, an outage is a crisis. Whole-Home Automatic Backup Power is the only real answer — not a surge strip, not a gas generator you have to drag out of the garage, but a fully automatic standby power system that kicks on within seconds and keeps your home or business running as if nothing happened. At FHR Electric, we design, install, and commission whole-home generator and battery backup systems for homeowners and business owners across Maricopa County — from North Scottsdale and Fountain Hills to Chandler, Gilbert, and Glendale — with every permit pulled and every connection made by licensed electricians who treat your property the way they’d treat their own.
Why Scottsdale Homeowners and Business Owners Are Done Gambling on Grid Power
Arizona’s electrical grid is reliable most of the time. But “most of the time” isn’t good enough when your sump pump fails, your smart home loses its settings, your refrigerator full of groceries spoils, or your child’s home oxygen concentrator goes silent. And if you run a business — a restaurant in Old Town Scottsdale, a dental practice in North Phoenix, a law office in Tempe — the financial and liability cost of even a two-hour outage can far exceed the cost of a properly installed backup power system.
We hear the same concerns from homeowners across Maricopa County every week:
- “We lost power during a monsoon and our HVAC was down for six hours — in August.”
- “My home office went dark in the middle of a client call and I couldn’t recover my work.”
- “My EV charger is on the same circuit as everything else and I’m terrified of an overloaded electrical panel.”
- “We have a gas generator but nobody ever starts it in time and it runs out of fuel by morning.”
A whole-home automatic backup power system eliminates all of those scenarios — permanently. And when it’s installed by a licensed, permitted electrician using quality equipment, it also adds measurable resale value to your home in a competitive Scottsdale market.
What We Install: Complete Backup Power Solutions for Every Need
No two homes or businesses have identical power needs, which is why we never sell a one-size-fits-all system. We assess your load, your priorities, your budget, and your property — then we build a solution around you. Here’s what we offer:
Standby Generator Installation (Natural Gas & Propane)
A permanently installed standby generator is the gold standard for whole-home backup power. Unlike portable generators, standby units are hardwired to your electrical panel, connected to your home’s gas line, and monitored automatically. When the grid drops, the generator starts within 10–30 seconds — no fumbling with extension cords, no gasoline runs, no manual switching. We install and wire standby generators ranging from 10 kW units ideal for essential circuits to 22–48 kW whole-home systems that power everything including central air conditioning, an EV charger circuit, and your home network. Every installation includes a properly sized automatic transfer switch, a dedicated new circuit installation where needed, and all required municipal permits.
Home Battery Backup Systems
Battery backup systems — including whole-home battery banks and units paired with solar — are increasingly popular in Scottsdale and across the Phoenix metro. They operate silently, require no fuel, and can often be configured to reduce peak-demand electricity costs. We install and commission battery backup systems that integrate with your existing panel or a new dedicated high-amperage circuit, handle the full wiring and commissioning, and ensure the system is code-compliant and properly permitted. A battery backup electrical install done right means your critical loads — refrigerator, lighting, internet, medical devices — stay on even if the outage lasts overnight.
Automatic Transfer Switch Installation
Already own a portable or standby generator but running it through a dangerous backfeed connection or a manual interlock? That’s a real hazard — for your family and for the utility linemen working to restore power on your street. We install automatic and manual transfer switches that safely isolate your home’s electrical system from the grid whenever backup power is active, eliminating backfeed risk and bringing your setup up to code.
Critical Circuit Subpanels
For homeowners who want backup power for specific loads — not the whole house — we can install a critical circuit subpanel that isolates your most important circuits: the refrigerator, primary lighting, HVAC, security system, a home office, or medical equipment. This approach dramatically reduces the generator or battery size required and is a cost-effective middle ground between a small portable unit and a full whole-home solution.
Business & Commercial Backup Power
For restaurant owners, medical and dental offices, and other commercial clients, we design backup power systems around true uptime requirements. A restaurant needs its POS system, refrigeration, and cooking equipment on separate protected circuits. A dental or medical practice may require an isolation transformer and a clean power source for sensitive equipment. If you operate a business that cannot afford downtime, we design a system around your operational priorities — not a generic template. Learn more about our specialized work for medical and dental office electrical services and restaurant electrical services to understand how we approach high-stakes commercial environments.
Why Proper Installation Is Non-Negotiable for Backup Power
We’ve seen it too many times: a homeowner buys a 22 kW generator and has a handyman or an unlicensed sub wire it in. No permit. No load calculation. Mismatched breaker and wire gauge. A transfer switch that isn’t rated for the load. And then one monsoon later, the system fails — or worse, it creates a fire hazard, a backfeed hazard for utility workers, or it fails a home inspection when the owner goes to sell.
Backup power is one of the highest-stakes electrical projects in a home. Here’s why doing it right matters:
- Code compliance and permits: In Arizona, backup generator and battery system installations require permits. Unpermitted wiring risks include failed home sales, insurance claim denials, and real legal liability. We pull all permits — every single time.
- Proper load calculations: A 200 amp service for a modern home with an EV charger, central air, and a home office has very specific surge and continuous load demands. We size every system correctly so it doesn’t fail under real-world conditions.
- Safe transfer switching: Backfeeding the grid through an improperly installed generator is illegal and deadly. Our automatic transfer switch installations protect your family and protect utility workers restoring power in your neighborhood.
- Warranty and insurance: Most generator manufacturers require professional installation for the warranty to be valid. Our installations keep those warranties intact and give your homeowner’s insurance company nothing to argue about at claim time.
- Lightning and surge protection: Lightning damage to home electrical systems is a real risk in the Valley’s monsoon season. A properly installed backup system includes surge protection that guards the generator, the transfer switch, and your panel from storm electrical damage.
“Backup power isn’t a luxury in Arizona anymore — it’s infrastructure. And like any infrastructure, it’s only as good as the people who install it.”

Our Process: From Assessment to Automatic Power, Start to Finish
We don’t show up and start drilling. Every backup power project at FHR Electric starts with a real conversation and a proper assessment, because the right system depends on factors that are unique to your home or business.
Step 1: On-Site Load Assessment
We visit your property in Scottsdale or anywhere in Maricopa County, walk through your panel, map your critical loads, and discuss your priorities. What absolutely cannot go down? What’s your fuel preference — natural gas, propane, or battery? Do you want whole-home coverage or critical circuits only? We gather that information before we recommend anything.
Step 2: System Design and Transparent Proposal
You receive a written proposal with a clearly defined scope of work, equipment specifications, and a firm price. No surprise invoices. No scope creep billed without your approval. If the project uncovers an issue — like an overloaded electrical panel or aging wiring that must be addressed — we tell you upfront, in plain language, with options.
Step 3: Permit and Equipment Procurement
We pull all required permits with the city or county before work begins. We source the generator, transfer switch, or battery system from reputable manufacturers and handle all logistics. You don’t have to coordinate anything.
Step 4: Professional Installation
Our licensed electricians handle everything — concrete pad preparation and mounting, gas line coordination, panel connections, transfer switch wiring, circuit additions, and grounding. We work cleanly, we protect your landscaping and flooring, and we leave the job site the way we found it.
Step 5: Testing, Commissioning, and Walkthrough
Before we close out the permit, we test the system under load. We simulate an outage, verify the automatic transfer, check every protected circuit, and confirm the generator or battery system performs exactly as designed. Then we walk you through the system so you understand how it operates, what maintenance it needs, and how to contact us if you ever have a question.
