New Home Battery Expands to 30 kWh, Starts at $1,757

Powering your home with solar energy just got easier and more affordable. Chinese manufacturer Anker Solix unveiled its Solarbank 4 E5000 Pro this week in Berlin, a modular battery system that starts at 5 kWh and can grow to store six times that amount.

The system connects directly to standard household outlets for basic installations, eliminating the need for expensive electrical work. Homeowners can plug in the 800-watt version themselves and immediately start storing solar power for nighttime use or backup during outages.

What makes this launch exciting is how it scales with your needs. The base unit holds 5 kWh of energy, enough to run essential appliances during a blackout. Need more capacity? Stack up to five additional battery units to reach 30 kWh of total storage, which could power an average home for days.

The system switches to backup mode in just 10 milliseconds when the grid goes down. That's fast enough to keep computers running and refrigerators humming without interruption. An exterior port delivers 2.5 kilowatts of off-grid power, plenty for most household needs during emergencies.

Anker Solix built the system to last, rating it for 10,000 charge cycles over 15 years. The lithium iron phosphate batteries can charge and discharge in temperatures from negative 4 degrees to 131 degrees Fahrenheit. An IP66 rating means the unit shrugs off rain, dust, and corrosion whether installed indoors or outdoors.

The Ripple Effect

This technology represents a shift in who can access residential solar storage. Traditional systems often require professional installation and cost significantly more, putting them out of reach for many households. By simplifying installation and reducing upfront costs, Anker Solix opens the door for more families to generate, store, and use their own clean energy.

The system's AI-powered software optimizes when to charge and discharge based on weather forecasts and electricity rates. For households on time-of-use pricing, that means automatically storing power when it's cheap and using it when rates spike. The company includes an AI voice assistant called Anka for hands-free monitoring and control.

To celebrate the launch, Anker Solix is offering 25 percent off through June, bringing the base system down to $1,757 from $1,999. Additional battery units cost $1,049 each during the promotion. The company is also throwing in a free smart meter for real-time energy monitoring with promotional codes.

The system has earned TÜV certification and integrates seven safety mechanisms to prevent short circuits and fire risks. It works with previous Anker Solix models and will soon connect to the company's Power Dock system for even more storage options.

More families can now take control of their energy future without breaking the bank or their circuit breaker.
