The smart all-in-one energy solution – for every application
VARTA.hybrid.wall is more than just an energy storage system: As an intelligently connected energy system made in Europe, it combines the VARTA.hybrid inverter and the VARTA.wall high-voltage storage into a modular, combining high-performance storage technology with advanced system control in one integrated solution. Whether used as a hybrid or AC-coupled solution, the system offers maximum flexibility for new and existing PV installations. Thanks to intelligent system control, it also enables simple and clear monitoring via our VARTA apps.
VARTA.hybrid inverter
Versatile – ready for the future
Whether AC-coupled for retrofitting an energy storage system or directly hybrid-coupled with PV integration: Thanks to its hybrid capability, the VARTA.hybrid inverter ensures a future-proof solution for expanding and modernising your PV system.1 Up to four independent MPP trackers ensure high yields even with different roof orientations or partial shading.
VARTA.wall energy storage system
Modular, powerful and ultra-slim
The plug-in system ensures fast, clean installation and maximum scalability – flexibly expandable to meet future requirements. With a depth of just 10–14 cm, the VARTA.wall is one of the most compact DC high-voltage storage systems in its class and, thanks to its dual-module design, offers greater flexibility – even in confined spaces. Two battery module variants enable flexible installation indoors, as well as in garages and covered outdoor areas, delivering reliable performance under a wide range of conditions.

The system that grows with you – the solution for every need
The first step towards a secure energy supply
The VARTA.hybrid.wall provides an easy-to-retrofit, modular all-in-one solution designed to maximise selfconsumption. Ideal for households with lower energy demand that want to invest gradually while staying prepared for future features.
Invest gradually – expand at any time
VARTA.hybrid.wall enables a flexible start to energy self-sufficiency: battery capacity and system functions can be expanded at any time – including future features such as dynamic or bidirectional charging, as well as tenant electricity solutions.
Easy to retrofit – maximum flexibility
The manufacturer-independent system enables straightforward and cost-effective integration into existing home electrical systems. Heating systems, EV charging infrastructure and PV extensions can be added flexibly at a later stage.
The intelligent all-in-one solution for demanding requirements
VARTA.wall, VARTA.hybrid, VARTA.iq and VARTA.backupswitch form an intelligent, fully integrated system that optimises energy costs, centrally controls loads, and ensures maximum supply security – even during a power outage.
Intelligent system control & maximum efficiency
VARTA.iq centrally coordinates more than 700 compatible devices and ensures optimal energy flows – even in complex installations with challenging roof structures, heat pumps, EV chargers and high loads. Automatic consumption analysis, intelligent heat pump control, live EV data and dynamic tariffs increase efficiency and unlock additional savings potential – including future revenue opportunities such as bidirectional charging.
Maximum reliability, cost optimisation & grid compliance
Optimised energy procurement based on dynamic tariffs, peak shaving and compliance with §14a control requirements ensure lower energy costs and full regulatory compliance. The VARTA. backupswitch ensures seamless backup power supply in the event of a power outage, allowing your entire household to continue operating without interruption and ensuring maximum operational reliability for connected loads.

VARTA.wall BM2 (4.5 / 9 / 13.5 / 18 kWh)
Mounting kit/wall bracket
(optional for wall-mounted installation)
Information
Variants
Direct measurement
Indirect measurement (including current transformers)
Notes
Precise measurement for maximum efficiency: the basis for intelligent charging and discharging processes. A VARTA.energymeter must be ordered in conjunction with a VARTA.hybrid model. For exceptions, see VARTA.backupswitch.
Information
Notes
In the event of a grid outage, the VARTA.backupswitch automatically disconnects the home grid from the public grid and enables a three-phase, fully automatic backup power supply.
As it includes integrated power measurement, a separate VARTA.energymeter is not required.
Expected to be available from Q3 2026.
Variants
VARTA.iq Basic (compatible with >300 devices)
VARTA.iq Pro (compatible with >700 devices)
Notes
The VARTA.iq Pro version will be available as a subscription model from June 2026.
VARTA recommends the VARTA.iq.link as soon as at least one controllable peripheral device is integrated into the household (e.g. a heat pump).
Information
VARTA.iq app in the Apple App Store
