Backup resilience
Identify the circuits and appliances that matter during an outage, then size the system around a realistic backup plan.
Residential energy storage · plan with confidence
Home battery backup built around the way your home uses power.
Prepare for outages, use more of your solar energy, and compare storage options by the things that matter: usable capacity, continuous output, installation, monitoring, and long-term service.
✓ Configuration-led advice✓ Clear trade-offs✓ No invented specs or ratings

Solar + storage
One clearer decision
One clearer decision
Start with the decision
A storage system is only useful when it fits your home.
Instead of leading with a single oversized specification, we help you compare the system against your outage priorities, solar production, critical loads, installation constraints, and service expectations.
Solar self-consumption
Use a storage plan to shift more of your generated energy into the hours your household actually needs it.
Clear installation path
Compare placement, electrical work, permits, monitoring, maintenance, and service before choosing a configuration.
01Define your critical loads
02Compare usable capacity
03Review installation conditions
04Choose a service path
How the plan works
Make the decision in three practical steps.
Good energy storage guidance is specific enough to act on and honest enough to show the limitations.
Map the home
Share your location, utility context, solar setup (if any), critical loads, outage concerns, and installation constraints.
Compare the fit
Review capacity, output, chemistry, expandability, operating conditions, warranty terms, monitoring, and installed cost as a set.
Plan the next step
Leave with a clear shortlist, the questions to ask an installer, and the information needed for an accurate quote.
Choose by situation
Different homes need different storage answers.
These starting points help you move from a broad “best battery” search to a decision that can actually be installed and used.
Frequent outages
Prioritize critical-load mapping, automatic transfer, continuous output, runtime assumptions, and service response.
Plan for resilience →Solar-first homes
Compare solar compatibility, charge/discharge behavior, monitoring, export rules, and the timing of household demand.
Compare the right fields →Smaller spaces
Start with placement, noise, temperature, electrical access, safety clearances, and the smallest useful configuration.
Read common questions →A better comparison framework
Do not compare batteries by capacity alone.
Use the same fields for every product. Ask for verified, date-stamped information before you publish or purchase.
| Field | Why it matters |
|---|---|
| Usable capacity | How much stored energy can be used in the intended operating conditions. |
| Continuous output | Whether the system can run the critical loads you actually care about. |
| Installation | Placement, electrical work, permits, transfer equipment and labor can change the real project cost. |
| Monitoring | Whether you can understand state of charge, events, alerts and system health. |
| Service terms | Who supports the system, where the warranty applies, and how issues are handled. |

Questions before you choose
Home battery backup FAQ.
These answers are intentionally practical. Exact sizing and pricing depend on the home, product configuration and local installation conditions.
How much home battery capacity do I need?
Start with the appliances and circuits you want to keep running, their power draw, expected runtime, and whether solar is available. A usable-capacity number alone is not enough; continuous output and transfer behavior matter too.
Is a home battery the same as a portable power station?
Not necessarily. A permanently installed system, a modular system and a portable unit can have different transfer equipment, installation requirements, operating limits, monitoring and service models. Compare the complete system, not just the battery box.
Can a battery work with my existing solar system?
Compatibility depends on the inverter architecture, electrical design, local rules and the storage system’s supported equipment. Confirm the complete installation design before relying on a compatibility claim.
What should I ask an installer?
Ask what loads are backed up, what assumptions determine capacity, what is included in the installed price, how permits are handled, what monitoring and service are provided, and what happens if a component needs replacement.
