Anker SOLIX No.1Anker SOLIX No.1
As the world's No. 1 in plug-and-play balcony solar battery storage, trusted by over 500,000 families, we know what matters most in real homes.
Introducing Anker PowerOS, the agentic home energy management system that makes saving effortless. It turns weather, energy prices, and your usage into a smarter daily plan.
It learns. It thinks. It acts. Smarter energy. Off your mind. On your side.
Understand Your Intent.
Reads Between the Lines.
No technical jargon needed. Just tell Anka how you live and what matters to you. Powered by Anker Intelligence, it understands casual or vague requests, adapts to changes, and turns them into an optimised energy plan. Effortless, convenient, and always in your control.

Just Say the Word. Anka Gets You.

Plans changed? Got several requests at once? No worries. Just talk to Anka. It re-plans, merges what fits, identifies conflicts, and runs the new plan once you confirm.

It Adapts to Your Situation

Adjust your strategy for different scenarios. Anka understands your intent, confirms it with you, then builds a plan that works.

It Asks to Clarify

If your requests conflict, Anka flags the issue and asks you which to prioritise before building the plan.

Manage Your Savings Without Always Watching
Anker Intelligence forecasts the weather, electricity prices, and your home's energy use to identify saving opportunities, select the best strategy, and coordinate your loads to make the most of every spare watt. When there's surplus power, Anka proactively alerts you. There's no need to keep checking the app or worry about missing an opportunity. Every watt, automatically maximised.

Automatic Tariff Matching. Always Optimised.

Whatever electricity tariff, the system automatically selects the most suitable strategy to maximise self-consumption and returns.

Dynamic Tariff

Connects to over 870 dynamic electricity pricing APIs worldwide, including EPEX Spot, Kraken, Amber, and Tibber. Tracks price fluctuations and automatically optimises battery charging and discharging for greater savings.

Time-of-Use Tariff

Reads half-hourly pricing periods and optimises electricity imports and exports independently to get the most from each.

Fixed Tariff

Maximises self-consumption by using solar power to charge the battery and run your heat pump and appliances.

Hands-Free Energy Wins, Every Time

*A household running Smart Mode improves PV utilisation by up to 25% by using surplus power and reducing solar clipping.

Surplus Alert and Utilisation

Always in the Loop. Always One Step Ahead.

Get alerts a day ahead, then again when surplus is available. Switch on demanding appliances and put every spare watt to work.

Full Solar Capture

Making the Most of Your PV Investment.

It frees up battery capacity ahead of time and charges in full during peak midday generation.

Your Smart Home, Your Power, Your Rules

Officially integrated with Home Assistant and Homey, it works seamlessly with your smart home devices. When there's surplus solar power, your appliances such as EV charger, washing machine, and heat pump, can put that extra energy to use. What to power? Your call.

VPP-Ready. Turn Surplus Power Into Income.

Got surplus power? You can participate in multiple VPP programmes and sell excess energy during periods of peak demand. Choose a programme and start unlocking lower bills, extra income, and faster payback.

Smart Reminders. Alerts You Before You Ask.
Stay one step ahead with timely updates. Every day, Anka reports on your energy use and flags potential risks before they become problems, so you stay informed and in control.
