U.S. Split-Phase Energy Storage Project: A Compact, All-in-One Solution

A sleek and highly integrated 11.4kW/10kWh split-phase energy storage system has been successfully deployed in the United States, serving as a key reference for modern residential and light-commercial applications. This project showcases a compact, wall-mounted solution designed to deliver energy independence, backup power, and enhanced efficiency for homes and small businesses.

Project Overview

This reference installation features a complete, wall-mounted storage system configured for 11.4kW/10kWh, perfectly suited for the standard 120/240V split-phase electrical service common in North American homes and small commercial properties. The all-in-one design integrates the battery unit, inverter, and critical management systems into a single, space-saving enclosure, presenting a clean, professional, and install-friendly aesthetic.

Technical Highlights: The Integrated All-in-One System

• Purpose-Built for Split-Phase Homes:​ The system is specifically engineered for the U.S. residential electrical grid, providing seamless integration for whole-home backup, solar self-consumption, and time-based load management.
• Space-Saving, Integrated Design:​ Unlike bulkier stackable systems, this solution consolidates core components into a single wall-mounted unit. This minimizes installation footprint, simplifies wiring, and offers a discreet, modern appearance suitable for garages, utility rooms, or exterior walls.
• Scalable Capacity:​ The modular architecture allows for the potential parallel connection of additional battery units, enabling homeowners to easily expand storage capacity as their energy needs evolve.
• Intelligent Energy Management:​ Equipped with advanced software, the system automatically optimizes energy flow. It prioritizes using solar power, stores excess energy, powers critical loads during outages, and can participate in utility demand response programs to generate additional value.

Market Value & Application

This project exemplifies the growing trend toward integrated residential storage in the U.S. market. For homeowners, it provides protection against power outages, maximizes the use of rooftop solar, and reduces reliance on the grid during peak—and most expensive—rate periods. The clean, compact design is a significant advantage for retrofits, where space and aesthetics are key considerations.

Conclusion

This 11.4kW/10kWh U.S. installation demonstrates that powerful home energy storage no longer requires a bulky, complex setup. It provides a compelling reference for a new generation of streamlined, intelligent, and user-friendly systems that empower American homeowners to take control of their energy use, enhance resilience, and manage electricity costs effectively.
