Owned Manufacturing & Quality Control
We don't just design our systems; we build them in our own state-of-the-art manufacturing facilities.
Owning our production lines means we maintain complete control over every step of the process, from sourcing raw materials (like premium LiFePO4 cells) to final assembly and rigorous safety testing. Nothing is outsourced; nothing is left to chance.
This vertical integration ensures that every stackable battery module and inverter that leaves our factory meets our exacting standards for durability, performance, and safety. It also allows us to manage our supply chain efficiently, ensuring reliable availability and faster delivery directly to your doorstep globally.
