Energy for Every Situation

Modular Build
Power That Scales with You

Each battery is packed with an innovative energy optimizer for independent charging and discharging, providing more attainable energy.

The energy optimizer is what makes the modular design possible, allowing you to scale output and capacity based on your needs.

Scale at Minimal Cost

Thanks to the modular design, you can start with a small system and add to it as your family grows. Every battery added connects to your system without energy loss.

Always-On Power
Ready for the Extreme

Extreme Off-Grid Performance

You're protected at all stages of an outage with X1 and its four off-grid features. They start long before a blackout occurs.
Before Outage
Outage Occurance
During Blackouts
Extended Outages
X1 activates Storm Guard mode automatically when the National Weather Service issues a warning. Your battery will be fully charged in case an outage occurs.
Storm Guard Mode
Storm Guard Mode Automatically detects and prepares for outages.
In less than 20ms, your power switches over to X1, so you can run appliances without interruption.
Under 20ms
Under 20ms Enjoy seamless backup transition.
Power with confidence thanks to the 1.1X rated power output. It's more than enough to run high-wattage home appliances at the same time.
1.1X Rated Power Output
1.1X Rated Power Output With InfiniPower™, you always have electricity.
Normally, blackouts disrupt solar systems, too. Not with X1. You'll have a constant power supply for several days of energy.
24/7 Solar Power
24/7 Solar Power Keep life smooth, even during lengthy outages.

Power Up with Extreme Toughness

Outages can be particularly brutal in the winter and summer. X1 is equipped to endure the extreme chill and heat with its superior build for peak performance.
100% Power at Frigid -4°F
X1 solves battery power challenges during freezing weather. Thermal boosting kicks in at 32°F and keeps the battery operating at 68°F.
100% Power at Ultra-Hot 131°F
IP65 Protection,
10-Year Warranty

5.9" Build Contains It All

X1 is ultra-thin and packed with a power density of 8.7W/ft³, the highest in the industry, thanks to its all-in-one design that combines battery and power modules. Install it almost anywhere around your home.
All in One

Smart Energy, Max Savings

X1 features seven distinct energy modes. Three are for emergencies and four of them can be switched interchangeably to give you the best position to manage your energy.
Profit in NEM 3.0 Mode
Activate with one tap in the Anker app to beat NEM 3.0. Charge X1 with cheap electricity prices during the day and sell back electricity at night during peak prices for a profit.
4.3X More Earnings
Profit when selling electricity under NEM 3.0 mode.
Self-Consumption Mode
Time-of-Use Mode
Off-Grid Mode
NEM 3.0 Mode
Minimize grid electricity. Your solar panels charge X1 and power your home during the day while you use X1 battery power at night. No grid power needed.
Minimize your electricity bill. Charge when energy prices are low overnight and during the day. Discharge when prices are high to avoid the surcharges.
Activate off-grid power. Manually switch to Off-Grid mode with just solar panels and X1.
Profit from your power. In California, X1 earns max revenue by selling solar generated power when prices are high.

Manage and Control in a Click

Real-Time Monitoring and Control
The Anker app gives you real-time data to monitor home power generation and consumption wherever you are.
Optimized with Data Insights

Safe and Reliable

Shock-Free 0V Shutdown
Your safety is our top priority. A zero-voltage shutdown activates during transportation, installation, and servicing to keep you safe from electric shock.
Abnormal Batteries Auto-Isolate
If a battery pack goes down, your power doesn't. Each battery pack contains an innovative energy optimizer. If something goes wrong, the failed module turns off, so power keeps going.
Stable LiFePO4 Batteries
The chemical makeup of LiFePO4 batteries in X1 is safe and stable. They can withstand thermal runaway between 572°F and 662°F, significantly higher than ternary lithium batteries.
Powerful and Quiet Operation
Rest easy with X1 operating at less than 40dB. It's much quieter than a rumbling gas generator.

  • The calculation of 2350kWh more energy is based on Anker SOLIX X1's 15kWh batteries compared to a traditional home battery over 10 years.
  • A soft starter is required when using X1 to power an air conditioner or a heat pump off-grid.
  • X1 must contain at least three battery modules to reach 100% power at 131°F.
  • 15% more energy at -4°F is calculated using a comparison to Anker SOLIX X1 without a BMS installed.
  • According to California's NEM 3.0 plan, the average price of electricity is $2.77 per kWh from Sept. 18th - 19th. The price of buying electricity from the grid follows is $0.65 per kWh. We used the following formula: 4.3X=$2.77/$0.65.
  • To be quieter than 40dB, the ambient temperature must be less than 104°F.
