Anker SOLIX Solarbank Max: 42kWh Plug-In Battery at IFA 2026

Anker used IFA Berlin 2026 (4-8 September, Messe Berlin) to unveil the SOLIX Solarbank Max, a plug-in hybrid battery Anker is calling the world's first plug-in home storage system capable of processing up to 10kWp of solar power directly. Unlike a typical balcony power station, the Solarbank Max connects up to 20 solar modules across three independent MPPTs and starts at 7kWh of storage, expandable to 42kWh — putting it somewhere between a balcony battery and a full home energy storage system.

What the Solarbank Max actually is

The base unit ships with 7kWh of usable capacity and its own micro-inverter, and Anker says up to five additional battery modules can be stacked onto it without extra wiring, taking total capacity to 42kWh. The headline number is solar input: three independent MPPTs let the Solarbank Max take in up to 10kWp from as many as 20 panels, considerably more than the 1-2 kWp ceiling typical of balcony solar kits. On the grid side, a professionally wired Wieland connection feeds up to 3,500W back into the household circuit (rising to 4,600W with a fixed installation) — figures corroborated across German outlets ComputerBase and Notebookcheck.

Built-in UPS and whole-home backup

The Solarbank Max carries a dedicated 3,680W AC outlet with an integrated uninterruptible power supply, switching to battery power with 0ms load-side interruption when the grid drops out. On its own, that socket covers partial emergency power for whatever's plugged directly into it. Anker says pairing the unit with its separately sold SOLIX Backup Auto Switch (single-phase) extends that to whole-home emergency power, automatically islanding the property's circuits from the grid during an outage. For UK readers weighing up backup capability against a conventional battery, our home battery storage buyer's guide covers how UPS-style switching compares with standard grid-tied setups.

Dynamic tariffs and local data processing

The Solarbank Max supports dynamic electricity tariffs out of the box: it can charge from the grid during the cheapest half-hourly rate periods and discharge — or avoid drawing from the grid — during the most expensive ones, on top of prioritising free solar generation. Anker says household energy data is processed locally on the unit rather than routed through the cloud, and the system integrates with Home Assistant for local automation. That tariff-shifting behaviour is the same principle UK households already use with agile import tariffs; see our rundown of Octopus tariffs for solar owners for how half-hourly pricing plays out on a UK electricity bill.

Price and warranty

Anker has set a recommended price of €2,499 for the 7kWh base unit, with an early-bird offer running 3 September to 21 October 2026 knocking €400 off and bundling a free Anker SOLIX Smart Meter Gen 2 (three-phase) — landing the launch price at roughly €2,099, as reported by Macerkopf and ComputerBase. The battery cells are rated for 10,000 charge cycles and Anker backs the unit with a 10-year warranty. No UK price has been published: at current EUR/GBP exchange rates €2,099 converts to roughly £1,800, but that's a currency conversion only, not a confirmed UK listing — UK pricing typically differs once import costs, VAT treatment and Anker's UK store margin are factored in, so treat that figure as an indicative ballpark rather than a retail price.

Not the Power Dock, and not the Solarbank Max AC

Anker's IFA 2026 stand includes several similarly named products worth keeping separate. The SOLIX Power Dock is a different product entirely — an EV-charging hub with built-in 11kW three-phase and 7.4kW single-phase charger ports, sold as the control unit for Anker's separate Solarbank Multisystem. And the Solarbank Max isn't the same as the Solarbank Max AC, the AC-coupled retrofit battery Anker launched back in April 2026: the Max AC is designed to bolt onto an existing rooftop solar array without direct PV input of its own, while the Solarbank Max announced at IFA has its own three MPPTs and takes solar panels straight into the unit. Anker's existing Solarbank 4 Pro, already on sale in the UK, is a smaller balcony-scale system again — none of the three are interchangeable, despite the overlapping branding.

What's still unconfirmed

Availability so far is confirmed for Germany, with the early-bird order window open now through Anker's own store. Anker has not announced UK availability, a UK price, or MCS certification status for the Solarbank Max at the time of writing, and none of the coverage from IFA week has specified a UK or EU-wide rollout date beyond the German launch. Buyers in the UK interested in the concept should treat this as a specification reveal rather than an imminent on-sale date, and check back for confirmed UK pricing before ordering via a grey-import route.
