Purpose-built by Powin for Powin Stacks

A Stack’s working environment is critical to the life span and safe operation of your storage asset. Our enclosures provide best-in-class monitoring, climate control, and fire suppression technology.

Safety and Reliability

We select the safest LFP cells on the market to integrate into our systems. Our proprietary StackOS battery management layer provides redundant safety features.

Cost Effective

Installation is at least 30% faster than traditional racking methods. We design our systems to lower the total cost of ownership over their lifetime, not just upfront capital costs.

Always Improving

We bring continuous innovation to the energy storage industry. We constantly add new software apps and features to our StackOS and StackOS+ platforms that can be retroactively updated onto existing hardware.
