Highlights of the VENUS E Family

VENUS E Mini — The World’s Slimmest Plug-in Battery

The VENUS E Mini emerges as a compact solution ideal for users with fundamental energy needs, especially in homes with space constraints. Featuring a bi-directional power of 1.5 kW and a backup output of the same capacity, it holds a storage capacity of 2 kWh. Powered by MARSTEK’s AI energy forecasting and presented in a sleek wall-mount design weighing only 22 kg, the VENUS E Mini provides flexibility and convenience for modern households.

VENUS E 4.0 — Optimized Performance for Solar Homes

Designed specifically for residences equipped with solar power setups, the VENUS E 4.0 combines an impressive charge and discharge capability of 3 kW along with a 5 kWh storage capacity in an optimized AC coupling structure. Its features include AI-driven energy optimization, Virtual Power Plant (VPP) functionality, whole-home backup capabilities, expansion options via SmartBox up to 9 kW/15 kWh, and seamless integration with electric vehicle chargers. This ensures a smarter and more efficient energy management system at home.

VENUS E MAX — First All-in-One 10 kWh Plug-in Battery

Developed for homes with significantly higher energy demands, the VENUS E MAX provides a bi-directional power of 3.6 kW and a 10 kWh storage solution all in one unit. This system is capable of parallel expansion via the SmartBox, allowing it to reach up to 10.8 kW/30 kWh. With AI-based energy management, VPP participation, whole-home energy backup, and electric vehicle charging integration, it creates a robust and scalable residential energy ecosystem.

VENUS E Pro — High Voltage Plug-in Battery

The VENUS E Pro combines a high voltage Maximum Power Point Tracking (MPPT) of 3 kW with an AC coupling system, all packed into a modular design. It starts with a storage capacity of 2.08 kWh, which can be expanded to 12.48 kWh without requiring more than two PV cables, simplifying installation and reducing wiring complexity. Thanks to fast EPS switching under 10 ms, a backup power capability of 2 kW, and LFP cells boasting over 10,000 cycles of lifespan, this unit is designed for efficiency and reliability.

Committing to the Future of Plug-in Batteries

To strengthen industry partnerships and deliver more insights to customers, MARSTEK plans to host a launch event for the VENUS E family and a dedicated workshop focused on the VENUS E Mini on June 30, 2026, in Eindhoven, Netherlands. Attendees will have the opportunity to dive deeper into the latest plug-in battery technologies while exploring future market trends in residential energy.

By merging smart software, flexible installation processes, and a scalable hardware architecture, MARSTEK is dedicated to making advanced residential energy storage more accessible, efficient, and user-friendly for homeowners globally, leading the next era of plug-in batteries.
