MARSTEK Unveils VENUS Energy Storage Systems at Solar Solutions Düsseldorf 2025

Introduction

On December 3 and 4, 2025, MARSTEK, a global leader in energy storage innovation, made a significant impact at the Solar Solutions Düsseldorf 2025 event. The company presented its latest energy storage solutions under the VENUS brand, showcasing state-of-the-art technology designed for efficiency and scalability in home energy management.

Highlighting the VENUS G

One of the standout products introduced was the VENUS G, a cutting-edge, stackable Energy Storage System (ESS) capable of delivering 5kW of AC power. An impressive feature of the VENUS G is its integration of 500V V-Boost technology, which enhances its efficiency. The system comes equipped with a bidirectional inverter capable of reaching a peak power of 10kW. This unique capability allows for ultra-fast backup switching, ensuring that homes remain powered during outages.

Moreover, the VENUS G supports modular capacity expansion, allowing users to increase storage from a starting point of 5kWh up to a substantial 30kWh. With a 7.5kW AC photovoltaic (PV) input, it facilitates seamless integration with popular solar systems such as Enphase and SolarEdge, and the same power input allows for swift, cost-effective charging when connected to the grid.

Future-Proof EV Charging with VENUS

MARSTEK also showcased its 11kW Three-Phase EV AC Charger, specifically engineered for compatibility with the MARS I PLUS Three-Phase system. This charger incorporates adaptive load balancing technology and robust protections (IP54/IK10), ensuring safety and reliability for users. Additionally, the charger is ISO 15118 ready, positioning it as a future-proof solution for electric vehicle (EV) users.

Additionally, the VENUS D (AC Version), another notable product, offers a plug-in ESS delivering 2.5kW of bidirectional power on-grid with peak backup support of up to 3.0kW. Its stackable design can be adjusted from 2.56kWh to 15.36kWh, providing customers with flexibility based on their energy needs.

AI-Driven Energy Management

The VENUS series is not just hardware-focused; it also features advanced AI-driven smart technology. The integration of AI forecasting allows for intelligent grid interaction, ensuring efficient and policy-compliant energy management. This smart technology enhances the overall user experience by optimizing power usage and ensuring that energy sources meet household demands effectively.

Exploring Other Innovations

In addition to the new VENUS products, MARSTEK introduced its Balcony ESS range, which includes models VENUS A, D, and E, all designed with the innovative Smartbox feature. Furthermore, residential energy storage solutions, such as the MARS I PLUS three-phase system and VENUS X, were displayed, emphasizing MARSTEK's commitment to scalable energy solutions.

Exclusive Launch Event

On the evening of December 3, MARSTEK organized an exclusive launch event for attendees. This was an opportunity for guests to experience first-hand the advancements within the VENUS series alongside the Home Energy Management System (HEMS). The HEMS platform showcases features like AI-powered energy optimization, smart management capabilities, and proactive backup power solutions that provide users with complete control over their home energy usage.
