Anker SOLIX Solarbank Max AC: 7 kWh plug-and-play home battery storage system for PV retrofits

The Anker SOLIX Solarbank Max AC is an AC-coupled all-in-one home energy storage system with a base capacity of 7,000 Wh that can be retrofitted to an existing photovoltaic system via a standard electrical outlet. Unlike the DC-coupled Solarbank models (Solarbank 3 Pro, Solarbank 4 Pro), it does not need to be compatible with the existing inverter: it comes with its own built-in inverter. With up to five BP7000 expansion batteries, the storage capacity can be expanded to up to 42,000 Wh.

Technical Specifications at a Glance

The Key Benefits of the Solarbank Max AC

AC Coupling: Retrofit Without Changing the System

Because the Solarbank Max AC is connected to the AC grid rather than directly to the PV string, it can be retrofitted regardless of the existing inverter or module type. This is particularly suitable for households that already operate a photovoltaic system without storage and want to add a battery to it later without modifying the existing system.

Large base capacity, expandable in modular increments up to 42 kWh

With a base capacity of 7,000 Wh, the Solarbank Max AC already covers the evening and nighttime energy consumption of an average household. Those who need more can combine up to five BP7000 expansion batteries to achieve a total capacity of up to 42 kWh—enough to meet high energy demands or get through several consecutive days with little sunlight.

Integrated Inverter with Emergency Power Function

The inverter is already built into the unit, so no separate component is required. The off-grid output allows selected loads to continue receiving power during a power outage.

IP66-rated and rugged housing for outdoor use

With an IP66 rating and an operating temperature range of −20 °C to +55 °C, the Solarbank Max AC is designed for year-round outdoor use, such as on a patio, in the garden, or mounted on a house wall.

Control via the Anker app

You can view the charge level, energy flow, and system status at any time in the Anker SOLIX app. Anker Intelligence automatically manages charging and discharging processes to increase self-consumption.

Compatibility: An Important Consideration Before Purchasing

The Solarbank Max AC is a standalone system with its own inverter and uses exclusively the Anker SOLIX BP7000 as its expansion battery—not the BP5000 or BP2700 modules from the DC-coupled Solarbank series. It can generally be combined with existing photovoltaic systems, regardless of the installed inverter, because the connection is made via the AC grid and not via the PV string.

Important Note Regarding Registration: If the output power is set to more than 800 W, registration with the relevant grid operator is required in Germany.

Who is the Anker SOLIX Solarbank Max AC suitable for?

The Solarbank Max AC is designed for anyone who wants to retrofit an existing photovoltaic system without storage with a home storage solution, without having to replace the existing system or the inverter. Thanks to its modular scalability up to 42 kWh, it is suitable for both smaller households with moderate energy consumption and households with high energy needs, such as those with a heat pump or electric car.

Frequently Asked Questions About the Anker SOLIX Solarbank Max AC

What does “AC-coupled” mean in the context of the Solarbank Max AC?

The Max AC Solar Bank connects to the AC grid via an outlet rather than directly to the PV string. It can be retrofitted regardless of the existing inverter or module type because it comes with its own built-in inverter.

How does the Max AC solar bank charge?

A standard, grounded household outlet is sufficient for up to 800 W without the need for an extension cord or power strip. For higher power ratings, a permanent connection via the terminal box with its own residual-current circuit breaker is required; this connection may only be installed by a licensed electrician.

Which extended-life batteries are compatible with the Solarbank Max AC?

Only the SOLIX BP7000 anchor. The BP5000 and BP2700 modules from the DC-coupled SolarBank series are not compatible.

Do I need to register the Solarbank Max AC with the utility company?

Yes, the Max AC solar bank must always be registered with the utility company, as it is a storage-only system without its own PV generation. If the output power exceeds 800 W, a Wieland connection (permanent connection) and installation by a licensed electrician are also required.
