Residential Energy Storage Systems
MARSTEK is Expanding the VENUS Series and Emphasizing Ease
Kalin Ned — September 6, 2025
MARSTEK is introducing a new line of residential energy storage systems under the VENUS series. This latest venture is designed to simplify the process of adopting solar power for homeowners. The systems are presented as a means to achieve greater energy independence and realize significant cost savings on electricity bills.
MARSTEK divides the core concept for its residential energy storage systems into two approaches. The 'Plug In' refers to compact, all-in-one balcony units that require minimal installation effort and can be connected without professional rewiring. The 'WireLite,' on the other hand, denotes larger capacity systems that aim to reduce the complexity and quantity of cabling needed for a full-home setup.
MARSTEK emphasizes key features of its VENUS series such as modular expandability for increasing storage capacity, artificial intelligence for optimizing energy usage based on time-of-use electricity pricing, and very fast switchover times to provide backup power during grid outages.
