The size most Melbourne homes actually end up buying.

What this size does to the house

What a single battery changes, and what it does not.

This is the size most Melbourne houses land on, and it is the one that usually fits the electrical installation you already have. A battery in this range is normally a single wall-mounted or floor-standing unit with one hybrid inverter, and on a standard single-phase supply it rarely forces a service upgrade. What it does force is a decision nobody mentions in the showroom: which circuits stay alive when the grid drops. Backup is not a property of the battery, it is a property of how it is wired. Keeping the whole house alive through an outage means a changeover arrangement and a switchboard that can carry it; keeping the fridge, some lights and a couple of power points alive means an essential-loads sub-board, which is smaller, cheaper to wire and what most households actually end up choosing once they see the two side by side. Decide that before the quote, not after the battery is on the wall.

Who it suits

And who it doesn't.

It suits a household that wants to stop exporting cheap solar in the afternoon and buying it back at night, and that can live with a limited set of circuits during a blackout. It suits an older weatherboard with a modest switchboard, because it asks the least of it. It does not suit a home already running ducted heating, an induction cooktop and a car charger off the same board and hoping the battery will carry all three overnight — that is a bigger battery and, more often than not, a bigger conversation about the supply itself.

Approved ranges in this band

Every approved range with a size in this band.

Sorted by brand rather than by capacity, because at this size the choice is usually made on what pairs with your inverter rather than on squeezing out another kilowatt-hour. Capped at 2 lines per brand so one modular range cannot fill the table — 170 lines shown, 76 more in the register. 84 of the 769 registered sizes in this band have already lapsed and 46 lapse within six months, which is why the expiry column is there.

A product line is one family, andsizes is how many separate configurations of it are registered — modular systems are registered once per stack size, which is why some lines show dozens. Usable capacity is the figure the certificate tiers are calculated on, and it is always lower than the nominal capacity printed on the box.Listing expires is the date the Clean Energy Council approval lapses; after it, that configuration can no longer earn certificates. All of it is as published in the Clean Energy Council approved battery list, so you can look up any line yourself.
