When the grid goes out
Power Outages
Keep basic home loads running during blackouts with home battery backup.
Home Battery Storage for Backup Power and Solar Use.
Keep your fridge, lights, WiFi, TV, security and home office running when the grid fails—or after sunset—with a home battery system.
What This System Does
Four simple jobs a home battery can do for you.
-
Home Backup
When the grid fails, keep fridge, lights, WiFi and key outlets on.
-
Solar Storage
Store free daytime solar power, then use it later at home.
-
Night Use
Run lights, WiFi, TV and home office after sunset.
-
Expandable
Start with a smaller battery, add more capacity later if needed.
Which Home Situation Is Yours?
Pick your situation first. Then choose battery size and whether you have solar.
If you have solar panels
Solar Energy Storage
Save extra daytime solar power in the battery, then use it in the evening.
After sunset every day
Night Use
Use stored power for lights, WiFi, TV and home office when the sun is down.
Unstable grid power
Weak Grid Homes
Help homes that lose power often or have unstable grid supply.
Before you order
Match Solar + Battery
Make sure your solar panels, inverter, battery size and backup loads fit together as one system.
What Can It Power?
These are the common home loads. Backup hours depend on how many you run at the same time.
-
Refrigerator
-
Lights
-
WiFi
-
TV
-
Phone Charging
-
Security Cameras
-
Home Office
-
Selected Outlets
Will It Work With My Home?
Answer these checks before you choose a battery.
-
No Solar Panels
No problem. The battery can charge from the grid and still give backup during outages.
-
Existing Solar System
You can add a battery later. First check that your solar inverter can work with the battery.
-
New Solar + Battery
Choose a hybrid system so solar charging, battery storage and backup power work in one setup.
-
Home Battery Voltage
Most homes use low-voltage batteries (48V or 51.2V). This is the common home battery type.
-
Expand Later
You can add more batteries later if the model, inverter power, wiring and install space allow it.
How Big a Battery Do I Need?
Start here. Final size still depends on your loads and how many backup hours you want.
01
5kWh Battery
Small start
Best for WiFi, lights, phone charging and a few small essentials.
02
10kWh Battery
Most homes
Best for refrigerator, WiFi, lights, TV, security and standard home backup.
03
15kWh Battery
Longer runtime
Best for longer night use, more home loads and larger solar homes.
04
20kWh Battery
Larger homes
Best for bigger homes, more backup loads and higher evening power use.

FAQ
What size battery do I need for my home?
List what must stay on (fridge, lights, WiFi, security, home office), how many hours you need, then match battery size and inverter power.
Can it run my refrigerator, WiFi, and lights?
Yes for most homes, if those loads fit the inverter power and battery capacity. Exact backup time still needs your real load list.
Can I use a battery without solar panels?
Yes. Charge from the grid and use the battery for backup when the power goes out.
Can I add a battery to my existing solar system?
Yes, after checking inverter type, battery voltage, communication, backup output, wiring and install space.
Is a 10kWh Battery enough for home backup?
For many homes, yes: fridge, WiFi, lights, TV, security and selected outlets. Air conditioners, pumps or whole-home backup need a larger size check.
Can the system be expanded later?
Yes, if your battery model, inverter, wiring and install space support adding more capacity.
