Anker SOLIX Solar Bank Max AC 7 kWh LFP Home Battery

The Anker SOLIX Solarbank Max AC (MPN: A17E23Z1) is an AC-coupled LFP home battery with a rated capacity of 7 kWh. The single-phase system is designed for retrofitting existing rooftop PV systems and microinverter systems. It stores energy on the AC side and later makes it available at the grid connection or to loads connected directly to the separate backup output. The storage capacity can be gradually expanded to 42 kWh with up to five BP7000 expansion batteries.

Key Benefits

• 7 kWh LFP storage system for AC-side retrofitting of existing PV systems

• Separate backup output with 3.5 kW active power for directly connected loads
• Control and monitoring via the Anker app and compatible smart meters
• IP66, natural convection cooling, and an operating temperature range of -20 to 55 °C
• Can be installed on the floor, indoors or outdoors
• 10-year manufacturer’s warranty; find more information here

AC retrofit for existing solar systems

The Solarbank does not have direct PV or MPPT inputs. It is integrated into an existing energy system on the AC side and is therefore particularly suitable for households that want to retrofit an existing PV system with a storage unit. A compatible smart meter monitors energy flows at the service entrance and enables control based on consumption or PV surplus. Supported models include the Anker SOLIX Smart Meter A17X7, the Anker SOLIX Smart Meter Gen 2, as well as the Shelly Pro 3EM and Shelly 3EM. The required meter is not included in the standard package and must be selected to match the existing electrical installation.

Connection Type and Available Power

The grid-side output power is set to 800 W in the basic configuration. For power up to 3.5 kW, a suitable separate circuit and a dedicated connection solution are required. Connection via a Wieland connector or hardwiring must be verified in accordance with the existing installation and performed by a licensed electrician. At the separate backup output, the device provides up to 3.5 kW of active power or 3.68 kVA of apparent power. This output is intended for directly connected loads and does not replace a three-phase emergency power supply for the entire home electrical system. For devices with high inrush current, the specified power peaks must also be taken into account.

Modular Design and System Control

The basic configuration combines storage, battery management, and inverter functions in a single enclosure. The expansion modules connect directly to the main unit; additional modules and required mounting accessories are available separately. The Anker app allows you to view operating data and energy flows, as well as configure available operating parameters. A suitable Wi-Fi signal is required at the installation site for setup. The system also supports an RS485 communication interface.
