Overview
These products represent infrastructure innovations currently in development and are not yet available for purchase.
Developed under the Monolith Guard™ security platform, the PowerVault Series is engineered to protect modern residential energy storage installations by providing secure, weather-resistant enclosures for home battery systems.
The system is being designed to provide hardened protection for external battery installations, including installations similar to the Tesla Powerwall and battery systems manufactured by SIG Energy.
As residential battery adoption increases across the UK, the PowerVault Series aims to deliver physical security, weather protection, and tamper resistance for wall-mounted battery storage systems installed in exposed locations such as external walls, garages, and utility areas.
The underlying enclosure architecture incorporates technologies currently subject to UK intellectual property protection, including patent-pending mechanisms and registered design rights owned by Sterling Grid Security Ltd.
