From September 23 to 25, 2025, SOLAR & STORAGE LIVE UK 2025—one of Europe’s largest exhibitions dedicated to the green energy transition, bringing together over 500 exhibitors and 20,000 industry professionals—was held at the Birmingham International Exhibition Centre. As an innovative force in the global low-carbon energy storage sector, MARSTEK made an impressive appearance with a portfolio of flagship products, including the VENUS series for balcony and home energy storage. Tailored to the UK’s green electricity application scenarios, MARSTEK’s solutions added a distinctive highlight to the exhibition’s sustainability theme.

As one of Europe’s core energy storage markets, the UK has witnessed a growing demand for green electricity in recent years. This exhibition provided a vital platform for industry technology exchange and cooperation. MARSTEK showcased four key products—VENUS E Gen 3.0, VENUS D, VENUS X, and MARS I PLUS—each delivering distinct core values tailored to the UK’s green electricity application needs.

VENUS E GEN 3.0: A plug-and-play energy storage system designed for households with existing photovoltaic installations. Featuring AC coupling technology, it offers a single-unit capacity of 5.12 kWh and supports parallel expansion of up to 9 units. When paired with a smart electricity meter, it enables “zero feed-in” operation and achieves 100% self-consumption of green electricity. With AI-based scheduling, it captures peak-valley electricity price differences to maximize household energy revenue, while its lightweight design makes it ideal for balcony installations.

VENUS D: A stackable AC-coupled balcony energy storage system tailored to the typical balcony layouts of British residences. It supports 4 MPPT with 4 kW solar input, 2.2 kW bidirectional grid-connected AC coupling, and 2.2 kW off-grid output (up to 2.5 kW). The system allows parallel operation of up to 3 units in single-phase and 9 units in three-phase setups. Equipped with AI-driven peak-valley electricity price management, it intelligently optimizes power consumption strategies, helping households reduce electricity costs.

VENUS X: An AC-coupled home energy storage system designed to meet the high-capacity electricity needs of British households. Starting at 10 kWh and expandable up to 60 kWh, it features 6 kW high-power bidirectional grid connectivity, fully compliant with UK grid regulation requirements. With streamlined AC-coupling wiring, it easily integrates with existing PV systems to enhance energy utilization while also providing reliable emergency backup power for households.

MARS I PLUS (Single-Phase): A 6-in-1 single-phase energy storage system featuring 550V V-Boost technology and a 6 kW hybrid inverter. It supports 12 kW solar input (expandable up to 48 kW) with dual MPPTs, and delivers 6 kW grid-connected AC output (expandable up to 24 kW). The system is also compatible with AC charging for electric vehicles, offering households a versatile and future-ready energy solution.

MARSTEK has always adhered to the core philosophy of “Reconstructing Home Energy Freedom through Technological Innovation.” At this exhibition, the company not only addressed market expectations for efficient green electricity utilization and stable power supply with targeted solutions, but also strengthened its role as a bridge for collaboration with industry partners. Looking ahead, MARSTEK will continue to advance its energy storage solutions through technological innovation—helping households reduce electricity costs, achieve energy autonomy, and contributing to the global green energy transition, while accelerating the realization of its vision of “Home Energy Freedom.”
