As Europe rapidly accelerates its transition toward renewable energy, the demand for accessible, high-efficiency home energy solutions has never been more critical. Against this dynamic backdrop, we at MARSTEK recently took center stage at EES Europe 2026—the continent's premier energy storage exhibition held in Munich. Dedicated to revolutionizing European residential solar storage, we proudly launched our brand-new VENUS E series of plug-and-play home storage solutions to the world.

Elevating Residential Storage

While Germany continues to lead Europe’s home energy storage market, traditional battery systems still bring universal headaches for installers and homeowners alike: complicated wiring, costly retrofits for existing solar setups, and minimal savings from time-of-use power rates.

We designed the VENUS E range to eliminate these barriers entirely. Every model features a true plug-and-play installation, requiring absolutely no rewiring of existing solar arrays and working seamlessly with all mainstream microinverters. Powered by our built-in AI time-of-use load shifting, we are delivering a portfolio of lightweight, affordable, smart, and long-lasting home storage systems perfectly engineered for European users.

Defining the Future: Our New VENUS E Series

To cater to a wide spectrum of household energy needs, our newly launched product matrix includes four standout innovations:

• VENUS E Pro: The High-Efficiency Integrator

  • An all-in-one plug-in battery featuring a 3kW high-voltage MPPT and 2kW AC coupling.

  • Its integrated MPPT trims standard 16 PV wiring runs down to just two, drastically slashing wiring costs.

  • It delivers 2kW bidirectional inverter power with a 2.4kW peak output and a seamless 10ms backup switchover during grid cuts.

  • Capacity scales flexibly from 2.08kWh to 12.48kWh to match rising household energy needs, while our inter-module active DC-DC voltage balancing ensures steady, reliable performance.

• VENUS E Max: The 10kWh Pioneer

  • Proudly standing as the world's first 10kWh all-in-one plug-in battery.

  • This standalone unit packs a massive 10kWh capacity and 3.6kW bidirectional charge/discharge power, providing 3.6kW of backup power that activates in under 10ms during blackouts.

  • Our SmartBox parallel system easily links multiple units to boost total power and storage capacity.

  • When paired with MARSTEK EV chargers, it allows stored solar energy to power electric vehicles, creating a fully self-sufficient home energy loop.

• VENUS E Mini: The Compact Powerhouse

  • An 800W/1.5kW 2kWh plug-in AC-coupled ESS that redefines spatial aesthetics.

  • Weighing only 22kg with a remarkably slim wall-mounted frame, this compact unit holds a standard 2kWh capacity.

  • Its AC-coupled design makes retrofitting existing solar setups incredibly quick and simple—a full plug-and-play installation takes just five minutes.

  • It provides 1.5kW bidirectional power with a peak backup output of 1.8kW.

• VENUS E GEN 4.0: The Upgraded Classic

  • Our fully optimized 3kW 5kWh plug-in battery, expertly tailored for homes with pre-installed solar panels.

  • While retaining its robust 3kW power and 5kWh capacity, we have successfully cut the unit weight by 21% and added an upgraded segment display.

  • SmartBox parallel expansion unlocks up to 9kW/15kWh of system capacity, and it integrates seamlessly with our MARSTEK EV chargers for smart charging control.

Empowering Europe's Renewable Shift

As a core exhibitor at EES Europe in Munich, we are more committed than ever to expanding our footprint across the continent. We will continuously refine our plug-and-play solar storage hardware around the genuine demands of local users, empowering European households to achieve full energy independence. Driven by innovation, our compact residential storage solutions will confidently speed up the continent’s shift to renewable power.
