GoodWe’s new ESA series storage product combines a hybrid inverter, battery units, and an integrated energy management system
The company claims that the ESS can meet a prosumer’s demands of up to 30 kW, with a corresponding storage capacity that can be scaled up to 108 kWh
According to the company, this product can operate at a minimum noise level of 30 dB for power ranges of 5 kW to 8 kW
GoodWe, a well-known provider of PV inverters and energy storage systems (ESS), organized a new product launch event on May 22, 2026, in Frankfurt, focusing on Germany’s residential storage market.
The highlights of the event were the new ESA series ESS, the product’s installation friendliness, Germany’s market dynamics, and live installation demonstrations.
Jie Zhang, General Manager of GoodWe Europe, opened the event with his keynote speech. He said, “As the European energy market continues to evolve, our commitment remains centered on three key principles: focus, long-term investment, and localization.” He showcased the latest 3-phase ESA series ESS, which combines a hybrid inverter, battery stack, and an energy management system on a single platform. This ‘All-in-One’ ESS (5-30 kW/5-108 kWh) offers flexibility for output demand and storage needs. It supports prosumer demands of up to 30 kW, with a storage capacity that can be expanded to 108 kWh.
The event also briefly delved into the company’s 4S concept – silent, smart, secure, and simple – based on which the product was built. For installation simplicity, each battery unit features a structure that allows installers to easily mount it vertically as a plug-and-play solution. A dual-output-port (grid and backup) design eliminates the need for separate wiring for an external static transfer switch. It has an integrated meter with clip-on current transformers (CTs) that require no cable cutting compared to traditional CTs, further simplifying the installation process. This process, including product repairability, was further evaluated and certified by TUV Rheinland.
In terms of silence, a part of 4S and an important aspect for German prosumers, this product can operate at a minimum of 30 dB between 5 and 8 kW. The company attributes this to the adoption of low-noise cooling fans, automatic internal temperature control in line with dynamic operating conditions, and the inclusion of an ultra-silent mode.
The system also features a Virtual Power Plant (VPP) mode that enables prosumers to participate in local VPP aggregator pools, generating additional revenue by discharging energy during high-tariff periods in response to the aggregator’s demand.
Sharing a presentation on Germany’s current market conditions and outlook, Susanne von Aichberger, Principal Analyst at S&P Global, claimed that the country is currently the largest behind-the-meter market and is expected to remain so until the end of the decade. With the withdrawal of feed-in payments for power during negative price periods, the scope for PV self-consumption for home storage will increase. Market analysts also predict that demand in the C&I storage market will ramp up by next year.
