Why add a battery

A solar battery turns your daytime surplus into evening power

Most Sydney households send the bulk of their solar to the grid for a feed-in tariff worth a fraction of what they pay to buy that power back after dark. A home solar battery closes that gap.

🔋

Use your own solar after dark

Charge the battery with your midday surplus, then run the house on it through the evening instead of buying power back at peak rates.

🏷️

Federal battery discount

The Cheaper Home Batteries Program takes roughly 30 per cent off the upfront cost. It is applied to your quote at the point of sale, not claimed back later.

NSW virtual power plant incentive

Connecting an eligible battery to an approved VPP attracts a separate one off NSW incentive that stacks with the federal discount.

📉

Less exposure to peak pricing

Time of use tariffs bite hardest in the late afternoon and evening. That is exactly the window a correctly sized battery covers.

🛡️

Backup for essential circuits

Batteries with backup capability can keep nominated circuits running during an outage. We confirm what your chosen hardware supports before you commit.

📱

Monitoring you can actually read

Track charging, discharging and how much of your own power you are using, so you can see the battery doing its job every day.

The process

From first call to first charge

A straightforward four step journey, with the same team looking after design, install and handover.

Free consultation

We review your bills, your usage pattern and any existing solar, then work out how much energy you actually shift after sunset.

Custom design & quote

You get an itemised proposal showing usable capacity, the federal discount already deducted, and what the battery is expected to cover.

Accredited install

Our SAA accredited team installs and commissions the battery to Australian standards, with the network paperwork handled for you.

Switch on & monitor

We set the charge and discharge behaviour, walk you through the monitoring app, and stay available if anything needs adjusting.

Built for Sydney

Solar battery installers who know how Sydney homes are supplied

A battery in Sydney is as much a compliance job as an electrical one. Ausgrid and Endeavour Energy each set their own rules for connecting storage, and where the battery goes has to work with heat, ventilation and clearance requirements on a tight suburban block.

  • Sized against your evening and overnight usage, so you are not paying for capacity you never cycle.
  • Placement assessed for temperature, ventilation and clearances, whether that is a garage, an external wall or a side passage.
  • Connection and metering paperwork prepared for your Ausgrid or Endeavour Energy supply area.
  • Federal discount applied on the quote, with your NSW VPP incentive eligibility explained before you sign anything.
Battery sizing

A battery sized to what your household uses at night

Indicative sizing below. Every quote is built from your own usage data, and capacity affects how much of the federal discount you receive.

Essential

5–10kWh

Smaller households and units

  • Covers the evening basics
  • Full discount rate on every kWh
  • Pairs with new or existing solar
  • Monitoring app included

Whole-home

14kWh+

Large homes, pools and heavy overnight use

  • Higher capacity, single or multiple units
  • Capacity above 14 kWh earns a reduced discount rate
  • Eligible up to 100 kWh usable capacity
  • Design checked against your network's rules

*The federal discount is delivered through small scale technology certificates. Its value depends on usable capacity and the certificate rate that applies on the date your battery is installed, and it steps down at regular intervals through to 2030. Capacity above 14 kWh attracts a reduced rate. Your quote shows the exact amount deducted.

Good to know

Solar battery questions, answered

How much can a solar battery save me?+
The saving comes from the gap between what you earn exporting solar and what you pay to import power in the evening. The bigger that gap and the more energy you use after dark, the more a battery is worth. We model your own numbers from your bills before you commit, rather than quoting an average.
What rebates are available for a solar battery in NSW?+
Two separate programs apply. The federal Cheaper Home Batteries Program cuts roughly 30 per cent off the upfront cost through small scale technology certificates, applied by us at the point of sale. Separately, the NSW virtual power plant incentive pays a one off amount for connecting an eligible battery to an approved VPP. The two can be claimed together on the same battery. We check what you qualify for as part of your quote.
Can I add a battery to solar I already have?+
Yes. Batteries can be retrofitted to an existing rooftop system or installed alongside a new one. We check your inverter setup and confirm the battery is on the approved product list so it remains eligible for the discount.
Will a battery keep my power on during a blackout?+
Only if the battery has backup capability and the install includes a dedicated backup circuit. In that setup, nominated circuits keep running while the rest of the house stays off. Not every battery supports it, so we confirm what is possible at your property before quoting.
What size solar battery do I need?+
It depends on how much energy you use once the sun goes down, not on the size of your solar array. Most households land somewhere between 10 and 14 kWh of usable capacity, which is also where the federal discount is at its most efficient per kilowatt hour. We size from your actual consumption.
