GoodWe is expanding the ET Series three-phase hybrid inverter with new models ranging from 80kW to 100kW, developed specifically for commercial and industrial (C&I) applications. As a core product of GoodWe’s C&I energy storage portfolio, the ET 80–100 kW delivers higher efficiency and full-chain flexibility through enhanced power harvest and strong backup capabilities. Seamless integration with GoodWe’s BAT 112 kWh high-voltage battery and Static Transfer Switch 125 kW (STS), position the ET 80–100 kW as a leading choice for almost all C&I scenarios.

Full-Chain Flexibility & Efficiency from DC to AC Side
The ET 80-100kW significantly increases energy harvest even in complex C&I scenarios, offering eight MPPTs with up to 42A input current, or 21A per string, making it compatible with M10 and M12 module sizes. AC and DC coupling offer great flexibility and efficiency. AC coupling is ideal for adding storage to existing PV systems without changing the original PV wiring, MPPTs, cables or PV inverters, while DC coupling reduces conversion stages to cut energy losses and improve round-trip efficiency by more than 2%. Together, they enable flexible system configurations for different project requirements.
The ET 80-100kW has been engineered for flexible configurations and easy expansion over the project lifetime. Dual 110A independent battery inputs provide up to 220A charge and discharge capability, delivering the high power required for C&I peak-shaving, backup and fast response to load changes.
All-Round Safety, Ultimate Reliability
Safety and reliability are built into every layer of the hybrid inverter. The ET Series has been awarded the TÜV Rheinland Certificate for Comprehensive Environmental Adaptability, demonstrating its ability to operate reliably in challenging outdoor conditions. The inverter features a smart fan reversal feature that automatically reverts direction of airflow during low power operation, reducing dust accumulation and corrective maintenance.
The ET Series inverter offers advanced features such as Arc-Fault Circuit Interrupter (AFCI 3.0) and Rapid-Shutdown Device (RSD) 2.0 for enhanced PV-side safety.
Terminal temperature monitoring on both AC and DC connections helps prevent overheating and ensures safe operation. Additional protections, including PV reverse polarity protection and ISO protection, guard the system from risks. The smart DC circuit breaker option can be selected on a case-by-case basis and adds another layer of protection. It automatically trips in the event of reverse polarity, DC terminal over-temperature or internal short circuits, quickly isolating faults to protect both equipment and personnel.
Backup Power and Flexible Expansion for Diverse C&I Scenarios
When combined with GoodWe’s STS 125kW, the ET 80-100kW delivers UPS-level switching with a transfer time of less than 4 ms, helping critical loads continue operation through grid disturbances without interruption. The advanced smart port design of the STS 125kW supports multi-purpose use of a single port, including generator start-stop control and flexible switching between generators and large loads.
When paired with GoodWe’s high-voltage BAT 112kWh batteries, the ET 80-100kW forms an easy-to-deploy, optimally matched storage solution. This pairing allows the battery to discharge close to its maximum capacity and ensures high power performance.
As a truly scenario-ready solution, the ET 80–100kW is designed to serve a wide range of C&I sites. Ultra-low noise operation below 60dB enhances user comfort in noise-sensitive environments such as business parks, office campuses and public facilities. Reverse rotating fans support dust removal and easy maintenance, making the inverter well suited for dusty outdoor and industrial environments. The continuous peak output power (without grid) of 110 % and 150 % peak output for 10 seconds ensures strong performance with demanding and uneven C&I loads, including motors, compressors and other impact loads.
For larger projects, the ET 80–100kW can be paralleled in systems of up to 15 units via the SEC3000C smart energy controller. SEC3000C also enables mixed-parallel operation of the ET 80–100kW with GoodWe grid-tied inverters, giving more flexibility to expand with storage.
With STS 125kW, BAT 112kWh battery and SEC3000C, the ET Series 80–100kW offers a safe, efficient and flexible C&I energy storage solution that is ready to grow with customers’ future needs.
