Introducing our 6th generation Technology Stack.

We understand that customers have unique energy challenges and there is no one-size-fits-all solution. We also know that the pace of storage procurements is rapidly accelerating and customers need to be able to procure and deploy at scale and across fleets with minimal risk.

With our sixth-generation technology stack, we’re making it simpler for customers to deploy storage faster and more cost effectively without sacrificing quality and configurability. Our tech stack lays the foundation for better energy storage with fully-integrated digital intelligence, an enhanced operating system, and factory-built, highly modular building blocks.

By pairing the benefits of mass production with the flexibility of a highly configurable system architecture, we can serve the diverse needs of customers around the world from a single, underlying technology stack.  The tech stack is delivered in three preconfigured systems, purpose-built for different customer segments and use cases.
