GoodWe Launches New ESA Series Residential All-in-One Storage Solution

GoodWe has officially unveiled its new ESA Series Residential All-in-One Solution, the latest generation of its popular household energy storage system. Building on the success of the first-generation ESA, this upgrade brings expanded power options, larger battery capacity, and smarter control to meet diverse household demands. Single-phase 3–10 kW hybrid inverter and 5–48 kWh battery integrate 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—Meeting Diverse Demands

Flexibility is at the heart of the ESA Series solution. Available in 3–10 kW power ratings and stackable with up to six batteries for a total of 48 kWh, the system can be tailored to different household needs—from powering essential appliances during short outages to covering the entire home’s daily energy use.

Installation is equally convenient. With one-click upgrade and configuration, the ESA Series can be set up in as little as 10 minutes—meaning families can enjoy clean, reliable power without complicated wiring or long installation time.

Unlike many systems that require all-new batteries for expansion, the ESA supports mixing new and existing batteries—even with different capacities. This makes it easy to expand household’s storage anytime without wasting their original investment, ensuring the system grows alongside the evolving energy needs.

Smarter Power, Lower Costs: Dual output ports & 1C charge/discharge & 200% PV oversizing

The ESA Series helps households save more while spending less. Dual output ports simplify the system setup by reducing the need for extra devices. This not only makes installation faster but also lowers long-term maintenance costs, while enabling full off-grid capability for added energy independence.

With 1C charge/discharge, the battery can cycle energy faster. In practice, this means a homeowner can achieve the same power output with fewer batteries, reducing upfront costs while speeding up the return on investment.

The product supports 20A per string PV input and 200% PV oversizing. By capturing more sunlight and converting it into usable energy, households can maximize their solar savings—even during cloudy days or when power demand peaks.

Home-Friendly Design: No noise & Harsh-proof & 6-layer protection

Designed with everyday family life in mind, the ESA Series combines comfort, quiet operation, and uncompromising safety. Its fanless design keeps noise levels below 30 dB—quieter than a bedroom at night—so it can be installed even in noise-sensitive areas without disrupting daily life. 

The built-in heating function ensures reliable performance in temperatures as low as -20°C, providing stable operation for households in regions with harsh winters such as Europe and Australia. In the event of a power outage, the ESA switches to backup mode in less than 4 milliseconds, fast enough that appliances like computers, lights, or Wi-Fi routers continue operating without interruption. 

Safety is safeguarded by an advanced six-layer protection system that monitors and protects the system from the battery cell all the way up to the overall unit, covering 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.

With its home-friendly design, high efficiency, and flexible expansion, the GoodWe ESA Series All-in-One Solution redefines residential energy storage. It empowers families to enjoy reliable backup, lower energy costs, and seamless integration into daily life—all while preparing for a smarter, more sustainable energy future.
