All battery units are designed to stack — in series to increase system voltage, in parallel to expand total capacity, or in a hybrid (series-parallel) configuration to meet exact voltage and capacity targets.
The Vault Series is engineered around a single principle: the system should be right-sized today and expandable tomorrow — without replacing what's already installed.
Each battery pack operates as an independent, intelligent module. Modules can be added, isolated for service, or upgraded without taking the whole system offline.
Begin with a single module and expand as demand grows. No system redesign required.
A faulty module is isolated automatically. The rest of the system continues operating.
Plug-and-play architecture reduces installation time and ongoing maintenance overhead.
Upgrade individual modules as technology improves — without replacing the inverter or battery bank.
Configurable for fixed commercial, mobile, industrial, or off-grid installations.
