A Riverwood factory warehouse put in a 200 kWh battery on a 50 kW inverter - four hours of push, and a A$15,000-a-year estimate
Dyness says a factory warehouse in Riverwood, Sydney now runs a 200 kWh STACK100 Pro battery with a Solis 50 kW hybrid inverter, signed up to a virtual power plant. Dyness expects about A$15,000 a year in power savings. The business is not named, and no system price is published.
A factory warehouse in Riverwood, in Sydney's south, has a new 200 kWh battery.
Battery maker Dyness published the case study on 10 October. The system is three stacks of 13 battery modules each, run through a Solis 50 kW high-voltage hybrid inverter. It is signed up to a virtual power plant, or VPP. Dyness says the site is expected to save about A$15,000 a year on electricity.
First, the terms. kW is how hard the system can push. kWh is how much the battery holds. Think of kW as the width of the tap and kWh as the size of the tank. Here the tap is 50 kW and the tank is 200 kWh. So the battery can run flat-out for about four hours (200 divided by 50). That is a long, slow battery, good for covering an evening or a peak window, not for big short bursts.
The VPP part. A virtual power plant links many batteries so an energy company can call on them when the grid is tight. You usually get paid or credited for that. The case study does not say who runs this VPP, how often they can drain the battery, or what the warehouse earns from it.
The rebate part. Dyness says NSW businesses installing 20 kWh to 30 MWh can use the NSW Batteries for Businesses incentive from 1 September 2026. We covered that scheme here: /news/nsw-business-battery-discount/. Dyness also says the federal Cheaper Home Batteries Program covers systems up to 100 kWh. By that description, a 200 kWh system like this one sits outside it.
Analogy: the inverter is the size of the door. The battery is the size of the shed. A big shed with a small door holds a lot, but you can only carry it out at one pace.
Workplace meaning. This is the size of job a small Australian manufacturer or warehouse can picture. A$15,000 a year is a real number to test against a quote. Divide your installed price, after incentives, by your own yearly saving and you get a rough payback in years. Dyness did not publish a price, so that sum is yours to do.
Good: Clear sizes, a named suburb, a dollar figure, and the incentive window spelled out.
Bad: The business is unnamed. No price, no payback, and no word on how much solar is on the roof. The A$15,000 is an estimate, not a measured year.
Ugly: This is a sales case study. VPP deals vary a lot. If the VPP drains the battery right before your own peak, your savings shrink. Read who controls the battery, and when, before you sign.
Soft next step: ask any installer for your peak window in kW and hours, then size the inverter to the kW and the battery to the hours. Then a short consult at Sovryn Energy /consult if you want that checked against your bill and the NSW incentive.
