Home battery storage, sized to your house

Most Melbourne homes export cheap solar at midday and buy it back at peak rates after 3 pm. A battery closes that gap: it stores the surplus and discharges it when you actually use power. We don’t sell a fixed package — we read your bill and usage pattern first, then specify the capacity and brand that fit.

What a battery actually changes

For a household on a Melbourne distribution network (Citipower / Powercor / United / Jemena / AusNet), the gains depend on your tariff and solar size. Here’s where they come from.

How we set the system up

Smart Energy Management

The battery charges and discharges around your tariff windows and solar generation, so it holds energy for the peak instead of dumping it early. Set-up includes real-time monitoring, automatic backup switching, app control and peak-shaving.

When the grid drops, a backup-capable system keeps your nominated circuits live. We’ll tell you upfront what your switchboard supports — whole-home backup isn’t always possible without works, and we won’t pretend otherwise.

Both FOX ESS and Sigenergy use lithium iron phosphate (LiFePO4) cells — the chemistry chosen for home storage because of its thermal stability and long cycle life compared with other lithium types.

Same team from assessment to commissioning to monitoring — you’re not handed to a sub-contractor. Installed by accredited installers.

Sized from your data, not a catalogue

We start with your last few bills and your solar setup, then specify capacity and brand against your real load. If a smaller battery makes more financial sense than a big one, that’s what we’ll quote.

Indicative system sizes

Every system is quoted from your usage — these are starting points, not fixed packages. Final capacity, brand and price depend on your bill, roof and tariff.

Small home — around 5 kWh usable

Suits smaller households or modest solar arrays where the aim is shifting daytime solar into the evening. Includes solar storage, essential-circuit backup, app monitoring and LiFePO4 cells.

Larger home — around 10-15 kWh usable

For larger households or higher evening loads — more stored capacity, longer backup runtime and higher solar self-consumption. Modular brands (Sigenergy) let you add capacity later. Whole-home backup subject to switchboard and inverter capability. May be eligible for current battery incentives — see our Incentives page.
