GoodWe Rolls Out Three-Phase All-in-One Storage Solution for Homes and Small Businesses

Following the strong market response to its single-phase ESA Series, GoodWe today announced the launch of its new three-phase All-in-One solution designed for residential and small commercial and industrial applications. Built to seamlessly integrate solar generation, storage, and energy management, this product sets a new standard in adaptable, high-performance energy solutions, delivering efficiency, independence, and peace of mind for a wide range of applications.

Install Easily, Expand Freely

Featuring a pre-wired modular design with one-click upgrade and configuration, the ESA three-phase system simplifies installation and commissioning, enabling users to get the system up and running quickly and effortlessly.

With four battery module options (5, 6, 8, and 9kWh), it supports flexible, on-demand capacity expansion through the mixed use of new, existing, and different-capacity battery modules—allowing upgrades without replacing existing equipment and effectively protecting the initial investment.

The system supports parallel connection of up to 12 battery modules for a maximum energy storage capacity of 108kWh, and up to six systems can operate in parallel on- and off-grid. This scalability makes the ESA three-phase (5–30kW / 5–108kWh) well suited for both residential and small commercial and industrial applications.

Maximize Power, Minimize Cost

Designed to deliver more power with less upfront investment, the system helps users maximize energy output while keeping system complexity and costs under control. Dual output ports streamline system architecture by reducing the need for additional devices, simplifying installation and lowering long-term maintenance requirements—while enabling full off-grid capability for greater energy independence.

High-performance 1C charge and discharge capability allows energy to cycle faster, meaning the same power output can be achieved with fewer battery modules. Combined with support for 21A per string PV input and up to 200% PV oversizing, the system captures and converts more solar energy into usable power—helping households increase solar self-consumption, accelerate return on investment, and maintain stable energy supply even during cloudy conditions or peak demand periods.

Smarter Energy, Greater Returns

Working seamlessly with GoodWe’s SEMS+ intelligent energy management platform, the system transforms high-performance hardware into maximum value for users. Using advanced AI algorithms, SEMS+ predicts power output based on weather data and intelligently optimizes charging and discharging, ensuring solar energy is used to its fullest potential.

The platform also provides detailed energy consumption insights and revenue reports, giving users transparent control over their energy use and helping them fully capture the financial and environmental benefits of clean energy.

Reliable Power, Peaceful Home

The ESA three-phase solution keeps your home safe with advanced AI-driven protection, including six-layer protection and AFCI 3.0 technology to prevent overheating, overcurrent, short circuits, and arc faults.

Built to perform reliably in all environments, the system features a built-in heating function for stable operation down to -20℃ and an IP66 rating for protection against dust and water—giving users confidence that their energy system will run smoothly no matter the conditions.

Designed with everyday life in mind, smart fan cooling keeps operating noise under 35dB, while ultra-fast backup switching in less than 4ms ensures uninterrupted power during outages—so your home stays quiet and comfortable even when the grid goes down.

From single-phase to three-phase, from residential to small C&I use, the GoodWe ESA All-in-One series continues to break through and innovate. The launch of this three-phase All-in-One redefines the energy storage standard for more scenarios with its core advantages of flexible expansion, intelligent cost saving, safety and reliability. 

In the future, GoodWe will continue to deepen its presence in the new energy field, providing global users with more intelligent and sustainable energy products and services, contributing to the construction of a green and low-carbon energy future.
