On March 10, 2026, MARSTEK, a leader in innovative energy storage solutions, announced the launch of its groundbreaking product, VENUS B, during a special event in Amsterdam. This remarkable addition to the energy storage market claims the title of the world's thinnest plug-in energy storage system (ESS), showcasing MARSTEK’s commitment to redefining modern energy solutions.

A New Era of Home Energy Storage

The VENUS B is specifically designed for contemporary homes and compact living environments. With an ultra-slim profile measuring just 8.6 centimeters and a lightweight design of 20 kilograms, it can be easily mounted on walls, making it an ideal solution for those who prioritize space efficiency. Despite its small size, the system offers a robust energy capacity of 2kWh and features a 1.5kW bidirectional inverter, capable of delivering 800W / 1.5kW for an on-grid output.

The plug-and-play nature of the VENUS B allows users to begin utilizing energy storage capabilities within moments of setup. Notably, it offers a quick 15-millisecond emergency backup switching, which ensures a seamless transition during power outages, maintaining a stable energy supply for everyday needs. Furthermore, its built-in AI-powered energy optimization software aids users in monitoring and managing their energy usage more intelligently, potentially saving up to €533 annually, which equates to around €1.46 per day.

Empowering Consumers with Energy Management

In conjunction with the launch of VENUS B, MARSTEK is also unveiling its new Energy Management Systems (EMS) supported by the MARSTEK App. This user-friendly application incorporates several innovative features aimed at enhancing energy efficiency and user experience:

• - AI-Driven Energy Optimization: A highly responsive system that continually adjusts settings for maximum energy efficiency and savings.
