Sungrow, a global provider of PV inverters and energy storage systems, showcased its latest portfolio of clean energy technologies at All-Energy Australia 2026, held in Melbourne on October 28–29. The company’s portfolio covered residential, commercial and industrial (C&I), and utility-scale applications, highlighting technologies aimed at supporting Australia’s transition towards a smarter and more resilient energy system.
From residential energy storage to commercial energy management and utility-scale grid solutions, Sungrow presented a range of technologies designed to address the evolving energy requirements of Australian households, businesses and grid operators.
PowerHarbour: Expanding Residential Energy Storage Options in Australia
Making its Australian debut, PowerHarbour is Sungrow’s latest residential energy storage offering, developed to address growing demand for home battery systems amid increasing government incentives and consumer interest in energy independence.
The system features a scalable architecture with a capacity of up to 120 kWh. Its mix-and-match 7 kWh and 10 kWh battery modules are compatible with Sungrow’s SHT and SHRS systems. The PowerHarbour Pro variant also incorporates an integrated EV charger designed to support future vehicle-to-everything (V2X) applications.
The system includes AFCI 3.0 protection to enhance electrical safety, while its streamlined architecture is designed to simplify installation. Built around Sungrow’s “Triple W” value proposition – Win More, Waste Less, Work Faster – PowerHarbour combines modular capacity, intelligent energy management and installation flexibility to accommodate changing household energy requirements.
C&I Innovation: Solutions Designed for Australian Conditions
For commercial and industrial applications, Sungrow demonstrated its energy storage solutions, highlighting their performance, safety and operational capabilities across different environments.
A live demonstration of PowerKeeper highlighted its water-submersion resilience and state-of-charge (SOC) stability, alongside its IP66 protection rating. Paired with the SH110CX inverter, PowerKeeper offers modular scalability from 100 kWh to 1 MWh and supports PV-plus-storage integration using existing cabling and meters.
The solution features 10 maximum power point trackers (MPPTs), a 2.0 DC/AC ratio and advanced algorithms for energy conversion and system management. Its functions include one-tap setup, real-time monitoring, AI-based self-diagnosis and Safe 7 Tech. Applications include peak shaving, self-consumption optimisation, virtual power plant (VPP) participation and Frequency Control Ancillary Services (FCAS).
Sungrow also showcased the PowerStack 255CS, rated at 110 kW/257 kWh. The system offers DC/AC conversion efficiency of up to 98.5% and incorporates three-level over-current protection and a liquid-cooled architecture. Its FCAS capabilities are designed to support participation in Australia’s energy market.
Together, the two solutions address commercial energy requirements through modular storage capacity, system integration and participation in grid-support services.
Utility-Scale Solutions: Supporting Grid Resilience
For utility-scale developers and engineering, procurement and construction (EPC) companies, Sungrow presented its PowerTitan 3.0 energy storage system and 1+X modular inverter, highlighting their capabilities for large-scale renewable energy and grid applications.
PowerTitan 3.0 integrates a 1.8 MW power conversion system (PCS) with 7.14 MWh of lithium iron phosphate (LFP) batteries within a 20-foot container. Its fully liquid-cooled design is intended to enhance system safety and operational life. The system also features noise levels below 65 dBA and grid-forming capabilities designed to support applications across both strong and weak grid conditions.
Complementing the storage system, Sungrow’s 1+X modular inverter features DC-coupled grid-forming capabilities and fast control response. Its modular architecture is designed to support rapid deployment and earlier commissioning, while its operations and maintenance (O&M) approach enables one-hour servicing to improve field efficiency.
Sungrow stated that its utility-scale technology portfolio is supported by local project management teams, grid and technical expertise, and a project pipeline of more than 10 GW across Australia and New Zealand.
Strengthening Sungrow’s Presence in Australia’s Renewable Energy Market
Sungrow highlighted its established local operations and service infrastructure as part of its long-term presence in the Australian renewable energy market. The company has more than 13 years of local experience, a team of over 100 professionals and a 3,000 m² Service and Logistics Centre.
Its local service network includes more than 300 service partners, supporting the deployment and maintenance of its solar and energy storage solutions.
Through its participation at All-Energy Australia 2026, Sungrow presented its residential, C&I and utility-scale technology portfolio, reflecting the growing role of integrated solar, battery storage and grid-support solutions in Australia’s evolving renewable energy landscape.
