Energy storage
Modular lithium storage that lets you use your own solar after dark, cut what you buy from the grid and keep essential circuits alive during an outage.
Battery brands we install
The range
Fox ESS
A high-performance, scalable high voltage storage system. The modular plug and play design lets you start small and add modules later as your usage grows.
Sungrow
Stackable 5 kWh modules with no cables between them — from 20 kWh up to 40 kWh per unit, and up to 160 kWh with four units in parallel.
Growatt
Cobalt-free LFP modules in 5 kWh blocks that stack without cables, scaling from a single 5 kWh unit right up to 400 kWh for larger sites.
GoodWe
An all-in-one system pairing a GoodWe hybrid inverter with matched battery storage, an optional static transfer switch and smart meter for whole-home backup.
ESY Sunhome
A sleek all-in-one wall unit combining hybrid inverter and battery in one enclosure — tidy on the wall and quick to install with fewer components.
Sigenergy
Inverter, battery, EV DC charger, PV optimiser and energy gateway in one modular stack — the most flexible premium storage system we install.

Energy storage
A battery needs solar — you must have a solar system installed for storage to work and to be eligible for the battery rebate. It stores the solar your roof makes during the day so you can use it at night instead of buying it back at peak rates. A hybrid inverter manages the flow: solar first to your loads, then to the battery, then to the grid — and in reverse after sunset.
Once your home's demand is met, the excess charges the battery rather than being exported for a small feed-in credit.
From late afternoon the battery covers cooking, heating, lighting and standby loads — usually the most expensive hours of the day.
Systems can also charge from cheap off-peak grid power in winter and discharge during peak windows, which cuts bills further.
Blackout protection is optional — request it and we fit a backup gateway so essential circuits keep running through an outage.
LFP batteries are rated for daily cycling for well over a decade, with warranties guaranteeing 60–70% of original capacity at end of term. In practice a well-installed, well-ventilated battery keeps working long past its warranty period.
Solar battery rebates
Since 1 July 2025 the federal Cheaper Home Batteries Program has cut roughly 30% off the installed cost of an eligible home battery, delivered as an up-front discount rather than a cheque. The discount steps down each year, so installing sooner keeps more of it. In New South Wales you can add the Peak Demand Reduction Scheme incentive on top when the battery is connected to a Virtual Power Plant.
Rebate amounts vary with product, capacity, location and the system being replaced, and program rules change over time. Eligibility is confirmed in writing before installation.
