Why Homeowners Are Choosing Battery Backup
Keep essential systems and appliances running during outages, storms, or grid failures.
Store excess solar energy and reduce reliance on the utility company during peak hours.
Stay powered when your neighborhood is not, without noisy generators or fuel concerns.
Lower peak energy usage and maximize the return on your solar investment.
MORE THAN A BATTERY
More Than Backup Power. A Smarter Energy System.
A whole house battery works best when it is part of a fully integrated energy system. Roswell Solar designs solutions that combine solar generation, battery storage, smart load management, and optional home automation to give homeowners true control over their energy use.
This approach improves efficiency, extends backup time during outages, and prepares your home for future energy needs.
A Smarter Home Energy System
Solar Energy
Clean energy generated on your roof to power your home and reduce dependence on the grid.
Battery Storage
Energy stored for outages, nighttime use, and high-demand periods when electricity costs more.
Load Management + Smart Controls
Your system automatically prioritizes essential circuits during outages. Optional smart controls help optimize how and when energy is used.

What Is a Whole House Battery Backup?
A whole house battery stores energy generated by your solar panels or pulled from the grid during off-peak hours. When the power goes out or energy costs rise, your battery automatically supplies electricity to your home.
Think of the battery as the control center that connects solar production, energy storage, and intelligent energy use. Unlike generators, battery systems are quiet, clean, and require no fuel or manual operation.
What Is Load Management?
Load management allows your battery system to intelligently control how energy is distributed throughout your home. During an outage, essential systems like refrigeration, lighting, internet, and medical equipment are prioritized so your stored energy lasts longer.
With optional smart controls, load management can also help reduce everyday energy waste and improve efficiency, even when the grid is online.
Residential Solar Payment and Incentive Options
Some utility providers offer net metering programs that allow homeowners to receive bill credits for excess energy produced. Availability varies by provider and location.
We offer financing and third-party ownership options that reduce or eliminate upfront costs while providing predictable monthly payments.
Certain local or utility-based programs may still apply. Our team helps you understand what options are available today.

Most Popular Questions
Most families want to know what can a whole battery power during an outage and if they can choose what stays powered during the outage?
Most homeowners don’t think in terms of “circuits.” They think in terms of what they want to keep running, such as:
- Refrigerator and freezer
- Lights in key rooms
- Internet and Wi-Fi
- Medical equipment
- Home office or security system
- Well pump or sump pump
During the design process, we translate those priorities into a system that supports what matters most to you. You don’t need to know the technical details, that’s our job.
Roswell Solar works with trusted, industry-leading battery manufacturers including Tesla, Enphase, and EG4. We recommend the best option based on your home, goals, and energy usage.
The right battery depends on how you live in your home, not just the brand.
For example:
- A smaller home that just needs to keep the fridge, lights, and internet on during outages may do well with a simpler system.
- A home with a well pump, multiple HVAC zones, an EV charger, or home office equipment often benefits from a more configurable system.
- Homeowners planning future additions like electric vehicles or expanded solar usually need a system that can grow without starting over.
We evaluate your home’s energy usage, electrical setup, and long-term plans before recommending a solution.
There isn’t a single “best” battery for every home, but there is a best option depending on how you want to use your power.
Here’s how the most common options compare in real-world scenarios:
- Tesla is often a good fit for homeowners who want a sleek, app-driven system with minimal decisions and a familiar brand name. It works well for standard backup needs with limited customization.
- Enphase integrates well with Enphase solar systems and is a solid choice for homeowners who already have Enphase equipment and want a straightforward, modular setup.
- EG4 is typically the best choice for homeowners who want more control, deeper customization, and better scalability. EG4 systems are ideal for larger homes, complex backup needs, advanced load management, and homeowners who want flexibility as their energy usage changes.
For many customers who want true whole-home backup or advanced energy control, EG4 offers the most robust and adaptable solution.
Load management decides where power goes.
Home automation decides when and how power is used.
For example:
- During an outage, the system automatically keeps essential systems running and limits non-essential usage.
- Smart controls can pause high-energy devices like EV chargers or pool equipment when backup power is limited.
- When the grid is online, automation can shift energy use to times when stored or solar energy is available, reducing reliance on utility power.
Automation is optional, but when paired with load management, it gives homeowners more control and efficiency without manual intervention.
It depends on your priorities.
Battery systems:
- Turn on automatically
- Are quiet and produce no fumes
- Require no fuel storage
- Work seamlessly with solar
- Are ideal for short-to-moderate outages and daily energy optimization
Generators:
• Can run for long periods if fuel is available
• Are loud and require regular maintenance
• Depend on fuel delivery during emergencies
• Typically require manual startup or monitoring
Many homeowners prefer batteries for everyday reliability and convenience. Others choose generators for extended outage coverage. In some cases, a hybrid approach may make sense.
