What Is Whole-Home Battery Storage?

Whole-home battery storage is a backup power solution that stores electricity in high-capacity batteries so your home can continue operating during utility outages. Unlike small portable generators, whole-home battery systems are designed to power multiple circuits — or even your entire home — safely and automatically.

Battery storage systems can be configured to:

• Provide backup power during outages

• Reduce reliance on the utility grid

• Support off-grid or semi off-grid operation

• Work alongside solar or as a standalone backup

In San Diego, battery storage is becoming increasingly popular due to power shutoffs, rising utility costs, and homeowners looking for energy independence.

Off-Grid Backup Power vs. Whole-Home Battery Backup

While these terms are often used interchangeably, there are important differences:

Off-Grid Backup Power

• Typically uses solar generators or battery-based power stations

• Can operate independently of the utility grid

• Ideal for rural homes or properties with frequent outages

• Often installed with a dedicated critical loads subpanel

Whole-Home Battery Backup

• Integrated directly with your main electrical panel or a backup subpanel

• Designed to power large portions of the home automatically

• Can be grid-tied, hybrid, or off-grid

• Scalable depending on home size and power needs

At Landers Electric, we design systems based on your actual electrical usage, not a one-size-fits-all approach.

How a Whole-Home Battery Storage System Is Installed (Step-by-Step)

Below is a realistic breakdown of what homeowners can expect when installing a battery backup system in San Diego.

Step 1: Home Electrical Load Assessment

We evaluate your electrical panel, service size, and existing loads to determine what can be backed up safely.

Step 2: Identify Critical vs. Whole-Home Loads

Some homes require only essential circuits backed up, while others want whole-home coverage. This determines system size and configuration.

Step 3: Battery System Selection

We select battery storage equipment based on:

• Power output (watts)

• Storage capacity (kWh)

• Expandability

• Compatibility with your home

Step 4: Off-Grid or Hybrid System Design

We design the system to operate:

• Fully off-grid

• Grid-tied with backup

• Hybrid (grid + battery + optional solar)

Step 5: Electrical Panel or Subpanel Modifications

This may include:

• Installing a critical loads subpanel

• Upgrading breakers

• Adjusting panel layout for safe backup operation

Step 6: Permitting & Code Compliance

All battery storage installations in San Diego require proper permits and must comply with NEC and CEC requirements. We handle the entire permitting process.

Step 7: Battery & Equipment Installation

Batteries are installed in approved locations with proper clearances, ventilation, and mounting methods.

Step 8: System Wiring & Integration

We safely connect the battery system to your electrical panel, backup circuits, or subpanel without backfeeding the utility grid.

Step 9: Testing & Commissioning

We test the system under load, simulate outages, and verify proper operation.

Step 10: Final Inspection & Homeowner Walkthrough

After inspection approval, we walk you through system operation, monitoring, and best practices.

Benefits of Battery Storage for San Diego Homeowners

• Protection during power outages

• Reduced reliance on utility power

• Quiet operation (no fuel or noise)

• No exhaust or emissions

• Expandable as energy needs grow

• Compatible with solar or non-solar homes

Battery storage is especially valuable in San Diego County, where public safety power shutoffs and grid instability are becoming more common.

Battery Storage vs. Traditional Generators

When you compare whole-home battery storage systems to traditional gas generators, here are the key differences:

• Noise Levels: Battery storage systems are silent, making them a great choice for residential areas. Traditional generators, on the other hand, are typically loud due to their internal combustion engines.

• Fuel Source: Battery systems use stored electricity, which can come from the grid or solar panels. Traditional generators rely on gasoline or propane, which means more ongoing fuel costs and handling.

• Maintenance: Battery storage systems require minimal maintenance compared to traditional generators, which need regular servicing and fuel management.

• Indoor Installation: Approved battery storage systems can often be installed indoors safely. Traditional generators must be placed outdoors due to exhaust and ventilation requirements.

• Permitting: While both systems require permits, battery storage installations generally only need electrical permits. Traditional generators may require both electrical and mechanical permits.

Because of these advantages, many homeowners in San Diego are opting for battery storage systems over traditional generators for their safety, convenience, and long-term reliability.

Do You Need a Panel Upgrade for Battery Storage?

Some homes may require an electrical panel upgrade before installing battery storage — especially older panels or undersized services.

If needed, we can:

• Upgrade your electrical panel

• Replace outdated or unsafe equipment

• Prepare your home for future energy upgrades

We evaluate this during the initial assessment so there are no surprises.
