Sungrow’s new all-in-one energy system brings together solar conversion, battery storage and electric vehicle charging, with simpler installation and smarter energy management among its promises for Australian households.

Sungrow has put its new PowerHarbour residential energy storage system at the centre of its display at All Energy Australia 2026, the Asia-Pacific region’s largest clean energy B2B exhibition and conference, in Melbourne 28 – 29 October. The showcased technology is designed to help households make greater use of rooftop solar and maintain efficient, low-cost electricity supply.

The PowerHarbour system reflects the growing convergence of home batteries, electric vehicles and intelligent energy management, bringing equipment previously installed as separate components into an integrated package.

Speaking at All Energy Australia, Sungrow technical support engineer and installer trainer, Graham Smith, said the design aimed to simplify both installation and everyday use, while continually driving down the cost of household electricity supply.

“The PowerHarbour puts everything into one box,” Smith said. “Previously, you’d have an inverter and a battery separate, and maybe even an EV car charger separate. This puts them all into one box.”

For homeowners, the intended result is a more compact system that stores surplus solar generation for later use, supports backup power and offers greater control over when electricity is consumed.

“It’s always about reducing your bills,” Smith said. “That’s why people are moving to battery storage. They want to reduce their power bills.”

More storage, greater flexibility

Smith said PowerHarbour would offer battery modules in 7 and 10 kilowatt-hour capacities, with configurations ranging from a single module to six modules in a stack. Adding a second stack could take storage capacity to as much as 120kWh.

That flexibility would extend PowerHarbour’s appeal beyond households to some small commercial premises. Smith said the range included inverter capacities reaching 30kW, opening applications such as medical and dental practices where continuity of electricity supply really matters.

He described a backup changeover time of 10 milliseconds, although the loads a particular installation can support will depend on its configuration.

Larger storage configurations could also appeal to customers considering Virtual Power Plants, which coordinate participating batteries to supply electricity or other services to the grid. Any financial return would depend on the relevant program, electricity tariffs and household consumption.

Smarter control of household energy

Alongside the new hardware, Sungrow is promoting artificial intelligence to help manage energy use.

Smith described Sungrow’s AI agent, called Bubbly, that allows users to ask questions or issue instructions through voice or text. Potential uses include help with battery schedules and system settings, as well as even providing assistance for installers diagnosing set-up problems.

A separate AI operating mode, Smith said, considers household consumption patterns, electricity tariffs and weather forecasts when calculating charging and discharging schedules.

“The AI mode will watch what you’re doing, the tariff rates, the weather and what the weather’s going to be, and calculate the best times to charge and discharge the battery,” Smith said.

The aim is to move beyond a basic pattern of storing surplus solar during the day and discharging it at night, adapting operation to the specific circumstances of each household.

Smith pointed to Sungrow’s after-sales service as making a big difference in the Australian marketplace.

“We are really there to back everyone up. We’ve got over 100 staff in Sydney. Nobody else in the battery business comes anywhere near that,” Smith said.

Making installation easier

Sungrow is also targeting the practical work involved in fitting home energy systems.

Smith said PowerHarbour’s stand-alone design and simplified connections could save installers around an hour on each site installation. Actual installation requirements will depend on the property and applicable standards.

“So it takes up less space, about a third of the space required by most battery systems currently on the market. Or if you use the same space, it can provide three times the power.

“It also has advantages in where you can actually site the system. You can put it in the garage with the charger for your EV or you can put it at the switchboard. And PowerHarbour is a stand-alone battery which you don’t have to fix to a wall, making installation easier,” Smith said.

Sungrow has also introduced a compact gateway called Energy Bridge, designed to fit inside a switchboard and manage backup functions while reducing the space and cabling required.

For Smith, who is also an experienced installer, training is central to turning these technical changes into useful outcomes.

“Part of my job is to help make sure that installers understand how this technology works, what actually happens and how it happens, so that they can then go with the knowledge and the confidence to answer all the likely questions from the customers,” he said.

Sungrow provides product training through its Smithfield training centre, site visits and online resources, including videos installers can consult while working.

Australian release awaits approvals

The new PowerHarbour product appeared alongside Sungrow’s broader exhibition portfolio, including PowerTitan 3.0, PowerStack and its 1+X Modular Inverter, spanning residential, commercial and utility-scale applications.

Smith indicated a first-quarter Australian release target for PowerHarbour, subject to Clean Energy Council approvals. He did not provide a confirmed price.

For households weighing up battery storage, installed cost, appropriate sizing and electricity tariffs will ultimately determine the financial case.

But the direction of Sungrow’s display was clear: home energy technology is becoming more integrated, with increasing attention being placed on how easily people can install, understand and operate it.

As Smith put it: “Our goal is to get the household energy bill down as low as possible. That’s what the customer wants,” Mr Smith said.
