GoodWe presented its 125 kW / 261 kWh ESA system for C&I storage, featuring liquid-cooled LFP batteries and an air-cooled PCS
The company’s utility-scale portfolio includes a 2 MW / 4 MWh containerized storage system with a specified round-trip efficiency of 90.5%
Residential hybrid storage systems and GT Series string inverters were also part of GoodWe’s REI 2026 showcase
GoodWe introduced its ESA 125 kW / 261 kWh battery energy storage system (BESS) for commercial and industrial (C&I) applications at the Battery Show 2026 in India. The system comprises a power conversion system (PCS), battery cells, a battery management system (BMS), and an energy management system (EMS) in a single cabinet.
The storage system is designed for applications such as factories and commercial complexes, and can operate in on-grid and off-grid configurations. Its integrated design simplifies installation and maintenance and allows multiple units to operate in parallel. The company states that up to 15 units can be connected in parallel to reach a combined capacity of 3.91 MWh in on-grid applications.
The storage system uses 314 Ah lithium iron phosphate (LFP) battery cells with liquid cooling, while the PCS uses air cooling. Other features include multi-level fire protection, pack-level humidity monitoring with automatic dehumidification, and AI-based battery diagnosis and health prediction.
GoodWe introduced a similar 125 kW / 261 kWh configuration earlier in 2025, which was also tested under the UL 9540A methodology for safety, fire prevention, and emergency response. Its latest launch therefore extends the company’s existing C&I offering in India.
The company also showcased its AC ESS 2 MW / 4 MWh system for utility-scale storage. Housed in a 20-foot container, it integrates the battery, PCS, energy management unit (EMU), and medium-voltage station (MVS). The company specifies a 90.5% round-trip efficiency for this product, which features an architecture that separates the AC and DC sections.
For residential applications, the company displayed two hybrid storage combinations: ES Uniq with Lynx A G3, and ET LV with Lynx A G4. These combine solar inverters, battery storage, and energy management for household applications.
GoodWe also highlighted its GT Series string inverters for C&I solar installations. The range offers 8 or 10 maximum power point trackers (MPPTs), 21 A input current per string, and up to 99% efficiency. Listed features include string-level monitoring, optional PID recovery, and Type II surge protection on both the AC and DC sides.
