Sungrow’s C&I DC-coupled 110 kW hybrid inverter supports a battery stack of up to 50 kWh storage capacity
The PowerTitan series storage platform, paired with modular inverter units, performs grid ancillary services
The company also promoted its EcoSync series hybrid inverter plus storage solution for residential applications
With the Australian PV market in focus, PV inverter and storage solution provider Sungrow showcased its product lineup at All Energy Australia 2025.
The company’s showcase featured 3 products: a commercial hybrid inverter with battery, a large-scale grid solution, and a residential system that combines rooftop solar with storage.
For commercial & industrial (C&I) users, Sungrow presented a solar-plus-storage system consisting a SH110CX series hybrid inverter and a ST050CF battery unit. The hybrid inverter is rated for a power output (AC) of up to 110 kW. The battery pack is rated for up to 50 kWh. Up to 100 such battery units can be connected in parallel, scaling up the capacity to 1 MWh. The inverter supports a DC-coupled configuration with up to 200% DC/AC optimizing capability, providing flexibility to accommodate up to 220 kW of PV installations and maximize solar energy harvesting. According to the company, its design, consisting of up to 10 MPPT channels, supports sectionalization of multiple PV strings for C&I roofs with multiple orientations or partial shading, without any loss of potential power generation. For real-time remote monitoring and control of the storage system, the company offers its latest iSolarCloud interface platform. It helps perform operational functions, like load-shaving and self-consumption optimization, typical for C&I use cases.
Sungrow also displayed the PowerTitan series utility storage platform, paired with 1+X modular inverter units. Housed in a 20 ft container, this solution is equipped with a Silicon-Carbide (SiC) based 1.72 MW power conversion system (PCS) featuring a conversion efficiency of up to 99.3%, and a lithium iron phosphate (LFP) battery stack with storage capacity of up to 6.9 MWh. The modular design of the 1+X inverters enables a flexible and scalable configuration. Unlike the single central inverter-based system, which completely shuts down itself during faults, the system continues to generate power by isolating only faulty inverter units. This feature also allows plant commissioning in phases and makes on-site maintenance more predictable. For grid-based ancillary services, it offers black-start capability and fast frequency response, among others, by leveraging the grid-forming control function.
Shifting to residential application, the company presented its EcoSync configuration, which integrates the SH15-25T inverter with SBH200-400 battery modules. The inverter and battery combination can maintain power during grid interruptions and is intended to support evening-peak demand using stored solar generation. This storage solution provides backup during grid failures or fluctuations, while supporting time-of-tariff-based operations.
The company’s press release didn’t include commercialization details for these products in Australia.
