Anker has introduced the Solix E10, a modular home battery backup system designed to compete with Tesla by providing whole-home power during blackouts. The system promises up to 15 days of off-grid survival for average households and features easy installation options. It is now available for pre-order starting at $4,299.
Anker is entering the competitive home battery market with its Solix E10 system, aimed directly at Tesla's offerings. Announced on January 13, 2026, the Solix E10 provides "whole-home backup" capable of powering heavy-duty appliances like air conditioners during outages. Its stackable, plug-and-play design supports DIY installation, potentially reducing costs compared to rivals.
Each E10 unit delivers up to 37.2kW of surge power, which doubles to 66kW when stacking two units. A "turbo output" mode allows 10kW per unit for up to 90 minutes. The system switches from grid to battery in just 20 milliseconds, minimizing disruption. Stacking three units reaches 90kWh capacity, sufficient for up to 15 days of average U.S. household use (around 30kWh per day), though this may vary by consumption.
For extended outages, the E10 integrates with Anker's tri-fuel Solix Smart Generator 5500, which runs on gasoline, propane, or natural gas to charge the batteries efficiently. It also accepts up to 9kW from solar panels per unit, scaling to 27kW with three. Optional accessories include the Power Dock for automatic 20ms switching and the Smart Inlet Box for manual operation and grid or solar charging.
Built with weatherproof all-metal enclosures, the E10 operates in temperatures from -4 to 131 degrees Fahrenheit, making it suitable for harsh conditions. Pricing starts at $4,299 for a single unit, rising to $5,799 with the Power Dock or $7,399 including the generator. Adding a second unit brings a full setup to about $10,000. Anker emphasizes lower installation costs due to its modular nature, with pre-orders now open.
