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.
