Sungrow, the PV inverter and energy storage maker, launched PowerHarbour in Australia on 28 October 2026 at All-Energy Australia in Melbourne. It's an all-in-one residential system that puts the inverter, energy management and stackable battery modules together, and in some configurations an EV charger too. Sungrow ties the launch to Australia's fast-growing home battery market, driven by the federal Cheaper Home Batteries Program.

What PowerHarbour does

  • Energy scheduling: Sungrow says the built-in management uses weather forecasts, solar production predictions, consumption patterns and electricity prices to decide when to store, use or export energy. Australian homes often get the most solar at midday and use the most power in the evening, and in some regions the Solar Sharer scheme gives free midday electricity.
  • Storage: stackable modules of up to 10 kWh each, with built-in battery optimisers and 314+ Ah cells. Supported combinations with extra battery clusters reach up to 120 kWh.
  • Solar: up to 200% PV oversizing in applicable configurations.
  • Retrofits: the new SMD battery modules can pair with some existing Sungrow storage inverters, including selected SHT and SHRS models. New and old modules can be mixed without state-of-charge calibration or pre-charging, according to Sungrow.
  • EV charging: the PowerHarbour Pro range has integrated charging in selected configurations and is designed with future V2X in mind. The SHSA-Pro model is marked "coming soon" in the Australian product presentation.

Hardware and installation

The enclosure is rated IP66 with C5 corrosion resistance for coastal and inland conditions, and some configurations are only 255 mm deep. Sungrow quotes noise below 30 dB(A). Applicable configurations include the EnergyBridge backup unit as standard, which combines five electrical functions in one device to cut separate wiring. Commissioning uses the plug-in iHomeManager Mini, and owners monitor generation, storage and consumption in the iSolarCloud app.

What's missing

The press release gives no prices, no list of exact models and capacities per configuration, and no release date beyond the Australian debut. It also says nothing about local interfaces such as Modbus or an open API, which is what decides whether a system like this can be read and controlled from Home Assistant or evcc without the cloud. If local control matters to you, check that before you buy.

The launch fits a broader trend: home batteries are turning into energy managers that decide on their own when to charge, discharge and run the car charger, instead of simply storing surplus solar.
