Backup Power Essentials: Generators vs. Home Batteries — What Fits Your Home?

Express Electrical Services is proud to serve Los Angeles and surrounding Southern California communities with trusted residential and commercial electrical solutions. Power outages are no longer rare inconveniences in our region — they’re part of everyday life. Between wildfire-related shutoffs, heatwaves, and rolling blackouts, families across Southern California are looking for reliable backup power solutions.

Two options stand out: generators and home batteries. But which one is right for your home? Let’s break down the pros, cons, and local considerations so you can make the best choice for your family.

Why Backup Power Is Critical in Southern California

  • Public Safety Power Shutoffs (PSPS): Utilities cut power during high fire-risk days.
  • Heatwaves: Increased AC usage drives rolling blackouts.
  • Grid Strain: California’s aging infrastructure struggles to meet demand.
  • Remote Work & EV Dependence: Homes need consistent power for work and transportation.

For homeowners in Los Angeles, Pasadena, Irvine, and beyond, having a backup solution is no longer optional — it’s essential for safety, comfort, and peace of mind.

Option 1: Generators

Generators provide backup power by burning fuel (natural gas, propane, or diesel) to create electricity.

Benefits:

  • Long Runtime: As long as you have fuel, generators can run for days.
  • Lower Upfront Cost: Typically less expensive to install than batteries.
  • Immediate Power: Automatically switches on during outages with a transfer switch.
  • Flexible Sizing: From small portable units to whole-home standby systems.

Drawbacks:

  • Noise: Generators can be loud, which is a concern in residential neighborhoods.
  • Emissions: Fuel-burning generators release pollutants.
  • Maintenance: Requires regular servicing and fuel storage.
  • Permitting: Some cities in LA and Orange County have restrictions on generator installations.

Option 2: Home Batteries

Home batteries store electricity from the grid or solar panels and provide silent, emissions-free backup power.

Benefits:

  • Clean & Quiet: No fumes or noise.
  • Solar Integration: Works seamlessly with rooftop solar to store clean energy.
  • Energy Bill Savings: Can shift usage to off-peak hours for lower costs.
  • Smart Features: Many systems include apps, monitoring, and AI integration.
  • No Fuel Dependency: Always ready to activate when the grid goes down.

Drawbacks:

  • Limited Runtime: Batteries have a finite capacity, usually powering essentials for hours or a day.
  • Higher Upfront Cost: Installation is more expensive than most generators.
  • Best with Solar: Without solar, batteries rely solely on grid charging.

Comparing Generators vs. Batteries

Feature Generator Home Battery
Noise Loud Silent
Emissions Produces exhaust Zero emissions
Fuel Source Gas, propane, diesel Grid or solar
Maintenance Requires regular service Minimal
Run Time Unlimited (with fuel) Limited by storage capacity
Best For Extended outages, rural homes Solar homes, eco-conscious living

Real-World Example: Los Angeles Home Chooses Both

A Los Angeles homeowner contacted Express Electrical Services after frequent outages disrupted their home office and EV charging.

Our solution:

  1. Installed a 200-amp solar-ready panel to expand capacity.
  2. Added a Tesla Powerwall for everyday outage protection and bill savings.
  3. Integrated a natural gas standby generator for extended outages.
  4. Installed whole-home surge protection to safeguard sensitive smart devices.

Now, the family enjoys the best of both worlds — a clean, quiet battery for daily resilience and a generator for rare but extended outages.

What to Consider Before Choosing

  • Length of Typical Outages: Short, frequent outages may favor batteries. Longer outages may favor generators.
  • Solar Ownership: If you have solar panels, batteries maximize your investment.
  • Budget: Generators are cheaper upfront, but batteries offer long-term savings.
  • Local Codes: Some LA County areas have restrictions on generators.
  • Environmental Concerns: Eco-conscious homeowners often prefer batteries.

Southern California Incentives

California offers programs that make batteries more affordable:

  • Self-Generation Incentive Program (SGIP): Rebates for installing home batteries, especially in wildfire-prone areas.
  • Federal Tax Credits: Cover a portion of installation costs for renewable energy systems.
  • Utility Rebates: Programs from LADWP, SCE, and SDG&E support battery adoption.

Generators typically don’t qualify for these incentives.

Mistakes Homeowners Make with Backup Power

  • DIY Installations: Unsafe wiring can cause fires or shock hazards.
  • Undersizing Systems: Choosing a generator or battery that can’t handle your household’s actual load.
  • Skipping Surge Protection: Outages and restarts often cause damaging surges.
  • Ignoring Maintenance: Generators, in particular, need regular servicing to remain reliable.
