MARSTEK Unveils the VENUS E Series at Intersolar Europe 2026

At the forefront of energy solutions, MARSTEK has presented its groundbreaking VENUS E series at Intersolar Europe 2026, which is taking place in Munich from June 23 to 25. This event marks a pivotal moment in the evolution of plug-in battery technology, showcasing a comprehensive range of products designed to support households in their energy transition.

Introduction to the VENUS E Series

The new VENUS E lineup includes several advanced battery options tailored for various energy needs. Among the highlights is the VENUS E Mini, marketed as the world's slimmest plug-in battery. Weighing just 22 kg, this compact solution features a bidirectional power of 1.5 kW, a backup output of 1.5 kW, and an AI-driven energy forecasting system, making it ideal for users with limited space.

The VENUS E 4.0: Optimized for Solar Energy

For households already equipped with solar panels, the VENUS E 4.0 offers enhanced capabilities. With a charging and discharging power of 3 kW and a storage capacity of 5 kWh, this model is designed for seamless integration into existing setups. Key features include AI energy management, a Virtual Power Plant (VPP) function, and compatibility with electric vehicle chargers, empowering homeowners to optimize their energy usage.

Introducing the VENUS E MAX: A Powerhouse for Large Energy Needs

The VENUS E MAX stands out as the first all-in-one plug-in battery with a substantial 10 kWh capacity. This model delivers a bidirectional power of 3.6 kW and can reach a total capacity of 30 kWh when paired with the SmartBox expansion. It's designed for users with higher energy demands, featuring AI management, VPP participation, and a comprehensive back-up power system。

VENUS E Pro: Cutting-Edge Modularity

Another remarkable addition is the VENUS E Pro, which integrates a high-voltage MPPT (Maximum Power Point Tracking) of 3 kW within a modular design. With a base capacity of 2.08 kWh expandable to 12.48 kWh, it supports an impressive input range of 50 to 500 V, allowing connection of multiple solar panels. Its simplified wiring process significantly reduces installation complexity, making it an appealing option for installers.

Launch Event and Future Prospects

To enhance collaboration with partners and clients, MARSTEK will hold a launch event for the VENUS E series, alongside a workshop centered around the VENUS E Mini, in Eindhoven, Netherlands, on June 30, 2026. These sessions are designed to provide an in-depth look at emerging battery technologies and energy storage trends.

By combining intelligent software solutions, flexible installation options, and scalable hardware architecture, MARSTEK aims to make home energy storage more accessible, efficient, and user-friendly. As a leader in the next generation of plug-in batteries, MARSTEK is committed to driving the future of energy solutions.
