Enhances Performance – manages battery operations, coordinating charging and discharging based on AI predictions and local data (e.g., utility signals, emergency alerts). Optimizes energy use for cost savings, ensuring uninterrupted power for critical operations such as data centers or manufacturing lines.
Enhances Efficiency – enables microgrid functionality, allowing independent operation during grid outages. For example, a 10kW solar system with a 30 kWh BESS can sustain a home for over 24 hours by prioritizing critical loads.
Enhances Resiliency - ensures uptime during outages, switching to backup mode in under 100 ms, minimizing financial losses (e.g., $100K / hour down time for large firms) while contributing stored energy to the grid via VPPs.

SUN TZU provides varied sizes of energy storage systems to be able to optimally fit the needs of your home. Additionally, each of our energy storage banks are stackable (expandable) to further dial in the ideal system for you.

SUN TZU Energy Storage Systems are designed with the most advanced technologies while utilizing the world’s most reliable materials to provide years of robust operational efficiency. We use commercial grade LFP battery chemistry coupled with advanced system design and functionality, while also providing user control through the SUN TZU App.

Built to support sustainable off-grid living and grid-tied resilience, each eCache unit includes 14.34kWh of scalable LFP battery storage, a high-performance hybrid inverter (10kW continuous / 11kW peak), and advanced load control through the Merlin System — providing seamless integration with solar systems for long-term energy independence.

The eHub Series empowers homeowners with sleek, space-efficient energy storage that combines intelligent design and reliable performance. Available in 5.12–10.24kWh configurations with 3–10kW output, eHub’s all-in-one system includes an AC-coupled inverter and smart management via the Merlin System.

Power your entire home with confidence. eHub Plus combines a large storage capacity of 15.3kWh with a built-in AC coupled hybrid inverter in one sleek stackable unit. Inverter options include 10 or 12Kw. Additionally, eHub Plus provides flexible user control via the Merlin System for the ultimate in control.
