GoodWe Launches New ESA Series Residential All-in-One Storage Solution
Munich, Germany, 05/11/2025
GoodWe has officially launched the next generation of their ESA Series Residential All-in-One Solution, bringing expanded power options, larger battery capacity, and smarter control to meet diverse household demands. The single-phase home storage solution is available with a hybrid inverter between 3 and 10 kW and stacked battery modules for 5 to 48 kWh storage capacity, integrating into one compact unit. Combining rapid charge & discharge, robust safety features, and a user-friendly design, it is tailored to deliver a quieter, easier, and more flexible energy experience for families.

More options, more flexibility
The ESA All-in-One offers a wide range of possibilities to combine inverters and batteries for different household needs. Available in six power ratings of 3 – 3.6 – 5 – 6 – 8 and 10 kW, the inverter sitting on top can be freely combined with up to six battery modules with a storage capacity of 5 or 8 kWh. The storage solution can be upgraded at any time, adding new batteries to the existing setup. This way, the system grows alongside the end users evolving energy needs. Designed for long-term use, the ESA comes with a conditional 10-year solution warranty, covering both the inverter and battery modules.

Installation is equally convenient with one-click upgrade and configuration, the ESA Series can be set up in as little as 10 minutes, significantly lowering time and effort needed by the installer. With an IP66 rating, the system can be installed inside or outside of the home and functions at temperatures as low as -18°C thanks to optional heating elements. No matter where it is installed, the design combines a modern look suitable for every home with fanless architecture resulting in quiet operation below 35 decibels. Both floor and wall mounting (with limited storage capacity due to the weight) are possible.
Smarter power for lower cost
The residential ESA is designed to help households lower electricity costs by increasing efficiency and limiting upfront spending. By supporting a maximum MPPT current of 20A on the PV side, larger capacity modules can be used with the system, and the 200% PV oversizing allows for more generation during off-peak hours and cloudy days. The low startup voltage of 50V enables a longer operational time, further increasing effective time of use. The inverter unit also allows for full usage when demand and solar yield peak, providing 100% supply to power the loads and charging the battery on full rate at the same time. The load control and monitoring enable the inverter, together with a GMK110 or GM330 smart meter, to dynamically turn on or modulate flexible electric loads, like heat pumps or water heaters, thus improving the self-consumption ratio.
The battery modules consist of high-quality lithium iron phosphate (LiFePO4) cells and have a 1C charge/discharge rate for faster energy cycles. In practice, this means the system can achieve the same power output with fewer batteries compared to offers with a lower C-rate. This makes it suitable for high instantaneous power scenarios such as load peak shaving and frequency regulation. Other operation modes include optimized self-use, backup operation, optimized time of use, smart charging and off grid mode. The off-grid mode is ideal for remote areas and locations without grid access, allowing independent power supply with solar. Strong scalability of up to 6 inverters and 288 kWh storage make the solution suitable for even larger locations.
The integrated backup function switches on in less than 4 milliseconds in the event of a power outage. This is fast enough for appliances like computers, lights, or Wi-Fi routers to continue operating without interruption. The backup is built in the system and doesn’t require any additional equipment.
Safety and Security
Safety and Security are at the heart of all GoodWe products, and the ESA Residential Series provides a high level of safety standards. With six-layer safety protection from cell level to system level and emergency protection including aerosol-based fire extinguishing, the system covers risks such as overheating, overcurrent, and short circuits. Adding another layer of protection, the ESA Series is equipped with AI-driven AFCI 3.0 technology, which intelligently detects and prevents arc faults. This greatly reduces the risk of electrical fires, giving homeowners peace of mind that their families and properties are well protected.
The ESA All-in-One solution also comes with the new Wi-Fi/LAN Kit 2.0 in the box, offering cyber security features according to the "EN 18031:2024" standard, having obtained CE-RED certification. The certification includes key features like password security, secure authentication during commissioning, signed and validated firmware updates as well as personal data protection.
