# Plug-In Energy Storage Systems MARSTEK's VENUS B is Noted to Be the World's Thinnest By Kalin Ned | Published 2026-03-10 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/plugin-energy-storage-system References: [prnewswire](https://www.prnewswire.com/news-releases/marstek-launches-venus-b--the-worlds-thinnest-plug-in-ess--redefining-the-future-of-plug-in-energy-302708908.html)  Energy storage innovator MARSTEK has launched the VENUS B — a plug-in energy storage system recognized as the world's thinnest — at Solar Solutions Amsterdam 2026. The innovation features an ultra-slim profile of just 8.6 centimeters and a lightweight, wall-mounted design. The appeal of this compact plug-in energy storage system is that it offers a powerful energy solution without sacrificing valuable floor space. As such, it can be seamlessly integrated into the home environment. MARSTEK's VENUS B's true plug-and-play installation eliminates the complexity and cost typically associated with home battery systems, allowing users to begin storing and utilizing energy within seconds, while the fifteen-millisecond backup switching provides crucial protection against power outages. The integration of artificial intelligence for energy optimization — a feature that can be managed through a user-friendly app — empowers homeowners to make smarter decisions about their consumption.
