Chinese inverter and storage system manufacturer Sungrow has unveiled this its new PowerHarbor all-in-one battery inverter for residential applications at the Smarter E trade show in Munich, Germany. “This is Sungrow’s first all-in-one product for the residential segment,” the company’s Team Leader for EU Solar/Storage, Andrea Polini, told pv magazine . “A key innovation of this new system lies in its modular battery architecture. Unlike previous Sungrow battery systems, where modules were connected in series and functioned as a single dependent unit, each module in the new design is equipped with its own optimizer. This makes every battery module fully independent and intelligently managed. As a result, new and older modules can be combined even years apart, with the system automatically balancing their operation to ensure optimal performance throughout the product’s lifetime.” This architecture also enables smarter energy usage, according to the manufacturer. “The system can selectively switch off battery modules when full capacity is not required, such as during periods of low household consumption at night or in winter. By only activating the necessary modules, overall efficiency is improved and the lifespan of the system is extended,” Polini went on to say. “It supports strong charge and discharge capabilities and is optimized for modern energy environments, including dynamic electricity tariffs and participation in virtual power plants. Using AI-driven control, the system can anticipate solar production and household demand. For example, it may delay charging in the morning if high solar production is expected later in the day, and then concentrate charging during peak photovoltaic output. This allows the system to better capture and utilize solar peaks, achieving up to 160% of nominal power during peak charging conditions.” The solution is also paired with a new device called the Energy Bridge, which acts as an integrated backup system. Designed in a compact circuit-breaker format, it replaces the traditional main household breaker and simplifies installation by eliminating the need for CT clamps. “Under normal operation, power flows through the system as usual, but in the event of a grid failure, the Energy Bridge automatically disconnects from the grid and enables immediate backup operation from the inverter, ensuring uninterrupted power supply at up to nominal inverter capacity,” Polini added. At the core of the system is a broad range of inverter power ratings tailored to different installation sizes. The smaller series delivers rated outputs of 10 kW, 12 kW, and 15 kW, while the larger series extends capabilities significantly, reaching from 17 kW up to 30 kW. This range allows the system to be deployed flexibly across a variety of residential and light commercial use cases, the company said. “The system offers flexible 10–30 kW power ratings and 6–10 kWh battery module options, with storage expandable up to 120 kWh,” it said in a statement. To maximize the use of solar energy during peak production periods, the inverters support a 1.6× PV-to-battery fast charging capability. Lower-capacity models provide up to 150% phase unbalanced output, while the premium SH30TA model supports up to 125%, ensuring stable performance even in uneven load scenarios, according to the manufacturer. Energy storage is provided through a stackable battery system built on 314 Ah ultra-capacity LiFePO4 prismatic cells. This modular architecture enables flexible scaling through multiple battery module options, including 5.7 kWh, 8.7 kWh, and 9.6 kWh units. The system reportedly achieves a lifecycle of up to 10,000 cycles under 90% depth of discharge testing conditions, making it suitable for long-term residential energy storage applications. Both the inverter and battery units are rated IP66. “Models up to 15 kW also feature fanless operation below 35 dB(A),” Sungrow stated. “Up to 150% three-phase unbalanced output can support high-demand appliances such as EV chargers and heat pumps, even when household demand is unevenly distributed across phases. This helps homeowners use more solar power directly in the home instead of limiting output.” From an installation perspective, the system adopts a modular, stacked floor-stand design that eliminates the need for inter-module wiring, significantly reducing installation complexity. Connectivity is streamlined through RJ45 quick-connect interfaces and integration with the iHomeManager Mini, which enables advanced system control and energy optimization, ensuring robust protection against dust and water ingress and allowing flexible installation both indoors and outdoors, the company said.
