The German battery manufacturer is expanding its portfolio with a modular scalable LFP storage solution with a new energy management system. The new product comes with the company’s proprietary “Varta.iq” software, which is designed to detect consumption anomalies, integrate dynamic electricity tariffs and enable bi-directional charging.
German battery manufacturer Varta is launching a new home energy storage system that uses artificial intelligence to detect anomalies in household energy consumption and adjust charging schedules accordingly.
The product, called Varta.wall BM2, is described as a modular solution with a capacity that can be scaled from 9 kWh to 13.5 kWh and 18 kWh. The battery modules are connected wirelessly. The charging and discharging power depends on the number of modules installed, ranging from 4.7 kW to 9.3 kW. Capacity and power can be expanded up to two years after commissioning. The maximum discharge current is 26 A for all versions. The operating voltage is 140–201 V in the smallest configuration and 280–403 V in the largest.
At the heart of the system is a new energy management platform, Varta.iq. It is compatible with more than 700 devices and integrates dynamic electricity rates. A “Pro” version is also available, which allows bi-directional charging applications.
“With the LFP-based Varta.wall and the intelligent energy management system Varta.iq, we now offer comprehensive solutions for sector coupling. This is the start of further innovative system additions to follow soon,” said Donny George, Managing Director of Varta Storage GmbH.
The system can control and monitor wallboxes, heat pumps and relays to adjust charging schedules based on weather forecasts, photovoltaic yields, consumption forecasts and dynamic electricity rates. Varta.iq can also be integrated into the ‘pulse neo’ and ‘element backup’ solutions, making it suitable for retrofit applications.
Like its predecessor, the BM2 comes in a 14 centimeter deep cast aluminum housing. With an IP55 protection rating, it is designed for indoor installation and for covered outdoor areas. The manufacturer specifies a permissible operating temperature of -10 C to 45 C.
The Varta.wall BM2 is compatible with Kostal Plenticore G2, G3 and MP G3 inverters, as well as the SMA Sunny Tripower Smart Energy and Kontron SolBrid.
The system is expected to be available from April.
