Home Battery Storage — Power Day & Night

Don't let your solar energy go to waste. Store it in a home battery and use it after dark, during peak rates, and when the grid goes down. Energy independence starts here.

Why Add a Battery?

Four Reasons Sydneysiders Are Going Battery

Energy prices are rising, blackouts are more frequent, and feed-in tariffs have dropped. A battery turns your solar from a daytime tool into a whole-home energy solution.

Slash Peak-Rate Bills

Use stored solar energy during 3pm–9pm peak tariff periods instead of drawing expensive grid power. Most households save an extra $600–$900/year.

Blackout Protection

Keep your lights, fridge, and essential appliances running during grid outages. A 10kWh battery keeps most homes running for 6–8 hours — or indefinitely when the sun is shining.

Maximize Your Solar

Without a battery, excess solar generation is exported for just 6–10c/kWh. With storage, you use that energy yourself at 28–35c/kWh — a 3–5× improvement in value.

Reduce Grid Dependence

Achieve 80–95% energy self-sufficiency with the right solar + battery combination. Protect yourself from future electricity price rises permanently.

How It Works

Charge by Day. Use at Night. Simple.

Home batteries work seamlessly with your solar system. Here's what happens in a typical day:

1

Morning: Solar Powers Your Home

From sunrise, your panels generate electricity that directly powers your appliances — dishwasher, washing machine, HVAC — at zero cost.

2

Midday: Excess Solar Charges the Battery

When your panels produce more than your home uses, the surplus charges your battery — instead of being exported cheaply to the grid.

3

Evening: Battery Powers Your Home

After sunset, your battery takes over. You avoid expensive peak-rate grid power entirely — the battery runs your lights, TV, cooking, and EV charging.

4

Blackout: Seamless Backup Switches On

If the grid goes down, your battery automatically switches to backup mode — usually within milliseconds. Your home keeps running while your neighbours go dark.

FAQ

Battery Storage Questions Answered

A 10kWh battery powering an average home (lights, fridge, TV, phone charging — around 1.5 kW average load) will run for 6–8 hours. If you have solar panels generating during the day, the battery will continuously recharge and could keep your home running indefinitely.
Yes, in most cases. If your existing inverter is battery-compatible (Sungrow, Fronius, SolarEdge, GoodWe), we can add storage to it with minimal changes. If it is not compatible, we can install a hybrid inverter alongside your existing system. We will assess your setup during the free site inspection.
Yes. The Cheaper Home Batteries Program offers up to $1,600 off eligible battery installations. You must be an existing solar system owner or be installing solar and battery together. SimpliSolar handles all eligibility checks — see our dedicated rebate page for full details.
Modern lithium batteries are rated for 6,000+ charge cycles, which equates to 15–20 years of daily cycling. All batteries we install carry a 10-year manufacturer warranty and retain at least 70% capacity at warranty end.
A battery alone (no solar) can be useful if you are on a time-of-use tariff — charging cheaply overnight and discharging in peak periods. However, the return is much lower than a solar + battery combination. We always recommend pairing storage with at least a 6.6kW solar system.
