Hybrid Backup Systems

For the people who really, really don't want to lose power.

A hybrid system pairs a battery with a generator. The battery handles the instant, seamless switchover—your clocks don't reset, your WiFi doesn't blink, your home office call doesn't drop. The generator provides unlimited runtime on natural gas. Together, they create backup power that has no gaps and no limits. It's the "belt and suspenders" approach, and for a certain type of Texas homeowner, it's the only option that makes sense.

The Concept

What Is a Hybrid Backup System?

Every backup technology has a weakness. Batteries run out. Generators have a 10-30 second startup gap. A hybrid system eliminates both weaknesses by combining both technologies into a single, coordinated system.

Battery's job

Instant switchover in milliseconds. Powers the home immediately with zero interruption. Handles short outages entirely on its own.

Generator's job

Unlimited runtime on natural gas. Takes over for extended outages and recharges the battery. Provides whole-home power indefinitely.

Think of it this way: The battery is the first responder—fast, silent, immediate. The generator is the cavalry—powerful, unlimited, ready for the long haul. Neither has to do the job it's bad at.

Step by Step

How It Works Together

Here's exactly what happens during an outage when you have a hybrid system.

01

Grid drops

Storm, ERCOT load shedding, transformer failure—the power goes out.

02

Battery takes over

In milliseconds. Your home never loses power. Not even for a blink.

03

Outage continues

Battery powers everything. If it's a short outage, the generator never needs to start.

04

Generator activates

If battery drops to threshold, the generator starts and powers home + recharges battery.

05

Grid returns

System automatically switches back. Generator stops. Battery recharges from grid. Done.

The Premium Choice

Why Hybrid Is the Premium Option

Zero-interruption switchover

The 10-30 second gap that generators have? Gone. Your battery bridges it instantly. Clocks don't reset, computers don't reboot, security cameras don't go dark. The outage is invisible to everything in your home.

Unlimited runtime

The capacity limitation that batteries have? Gone. Your generator provides power for as long as the outage lasts—days, weeks, it doesn't matter. And it keeps your battery charged too, so if the generator cycles off, the battery is ready.

Intelligent management

Modern hybrid systems don't just coexist—they coordinate. The system decides when to use battery, when to start the generator, when to recharge, and when to switch back to grid. You set your preferences once and forget about it.

Configurations

Sample Hybrid Configurations

These are real-world configurations our installers commonly deploy in Texas homes. Prices include all equipment and installation.

Essential Hybrid

1x Tesla Powerwall 3 (13.5 kWh)
Generac Guardian 18kW
$22,000–$28,000 installed

Homes that want seamless switchover with unlimited backup for essentials.

The battery handles instant switchover and powers your home for the first few hours. If the outage extends, the generator kicks in automatically and can also recharge the battery. Best for 2,000-3,000 sq ft homes.

Whole-Home Hybrid

2x Tesla Powerwall 3 (27 kWh)
Generac Guardian 22kW
$32,000–$42,000 installed

Large homes that refuse to compromise on anything—ever.

Dual batteries provide 12-24 hours of whole-home backup independently. The generator provides indefinite runtime when needed and keeps batteries topped off. Full coverage for 3,000-5,000 sq ft homes with dual AC systems.

Solar Hybrid

2x FranklinWH (27.2 kWh)
Kohler 20kW
$45,000–$60,000 installed

The ultimate setup. Solar recharges batteries daily, generator as final backstop.

FranklinWH's smart panel manages solar, battery, generator, and grid seamlessly. Solar recharges batteries during the day, generator activates only when batteries are low and sun is down. Includes the 30% federal tax credit on solar and battery components.

Honest Assessment

Is Hybrid Overkill?

Hybrid makes sense if...

  • Zero-second switchover is non-negotiable (medical equipment, home office)
  • You want indefinite runtime AND silent instant transition
  • You have solar and want maximum self-sufficiency
  • Your home is 3,000+ sq ft and you want every circuit covered
  • You experienced Uri and never want to think about outages again
  • You value having redundant systems (belt and suspenders mindset)

You probably don't need hybrid if...

  • A 10-second power gap during switchover doesn't bother you (generator alone works)
  • Your outages are typically under 8 hours (battery alone handles it)
  • You're optimizing for the lowest possible cost
  • You don't have specific equipment that requires uninterrupted power
  • Your home is under 2,000 sq ft (simpler solutions work fine)

We'll be straight with you: most Texas homes don't need a hybrid system. A standalone battery or generator handles the job. But for the homeowners who want the absolute best—zero gaps, zero limits, zero compromise—hybrid is the answer. And we're not going to upsell you on it if you don't need it.

Common Questions

Hybrid System FAQ

Each solves the other's weakness. Batteries switch over in milliseconds (generators take 10-30 seconds), so you never lose power—not even for a moment. No clocks to reset, no computers rebooting, no WiFi dropping. But batteries have limited capacity. A generator provides unlimited runtime on natural gas but has that brief switchover gap. Together, you get instant switchover AND unlimited runtime. It's the difference between 'good backup' and 'you literally cannot tell the power went out.'
