Solar Batteries for Smart Storage
Stay Green with COYCO
Honest advice on Solar Batteries from Rockingham Experts.
Expert Supply & Install of Solar Batteries in Rockingham
Solar Battery Storage: Moving to Energy Independence
Be energy independent with a Solar Battery.
Daytime: Your panels make power. Any extra energy automatically goes into the battery instead of being sold back to the grid for almost nothing.
Nighttime & Peak Use: Use this stored battery power at night, when grid electricity is expensive, or as backup if the power goes out.
This capability significantly boosts how much of your own power you use, making your Solar Installation a better investment.
Key Benefits of Solar Battery Storage:
Peak Time Savings: Use stored solar power at night or during peak times when grid electricity is most expensive.
Blackout Protection: Provides essential backup power to keep critical circuits (like fridges & lights) running during power outages.
Reduce Grid Reliance: Stop selling your excess solar power back to the grid cheaply. Storing it leads to much bigger long-term savings.
Future-Proofing: Installing a high-quality, battery-ready Solar Inverter now prepares your home for future battery integration.

Frequently Asked Questions
Your Solar Batteries Questions, Answered.
Which battery brands do you recommend?
At COYCO, we don’t believe in “one-size-fits-all” solar. However, after years of installing and servicing systems across Western Australia, our primary recommendation is the iStore Home Battery and Smart Hybrid Inverter ecosystem.
As an iStore Preferred Partner, we recommend this hardware for three main reasons:
1. The Power of “Modular” Design
Unlike traditional “all-in-one” batteries that are fixed in size, the iStore system is modular.
Start Small or Go Big: You can start with a single 5kWh module and literally stack more on top (up to 30kWh) as your family grows or you add an EV.
Future-Proof: You aren’t locked into the capacity you buy today. If you find you need more storage in two years, we simply come back and add another block to the stack.
2. Seamless Ecosystem Integration
When you pair an iStore Hybrid Inverter with an iStore Battery, the two units speak the same language.
The “Brain”: The inverter acts as the mission control for your home, intelligently deciding when to charge the battery, when to heat your water via your iStore Heat Pump, and when to power your home.
One App to Rule Them All: You can monitor your entire energy “ecosystem” (Inverter, Battery, Heat Pump, and EV Charger) from a single, easy-to-use Australian-supported app.
3. Built for the WA Climate
iStore is an Australian-owned brand. Their batteries and inverters are designed to handle the extreme heat of a Perth summer. While some international brands struggle when the temperature hits 40°C, iStore systems are engineered for high-ambient temperature performance and longevity.
4. Preferred Partner Peace of Mind
Because COYCO is a Preferred Partner, our customers receive:
Priority Technical Support: Direct access to iStore engineers.
Expert Installation: Our team is factory-trained on this specific hardware.
Long-Term Reliability: We only recommend brands that we know have a strong physical presence in Australia for warranty and parts.
Want to see a stack in person? We have the iStore battery and inverter system on display at our Rockingham Showroom (Unit 2/5 Leach Crescent). Come in and see how the modular blocks fit together!
What does 'Energy Payback' mean in relation to solar batteries?
Energy payback refers to the time it takes for the savings generated by your battery to equal its initial cost. By using your stored power instead of buying expensive grid electricity—especially during peak rates—you are maximizing your savings. This significantly shortens the time it takes for the battery to pay for itself, making your Solar Installation a better long-term investment.
What is a 'battery-ready' system?
A battery-ready system uses a hybrid inverter which can manage power flow from solar panels, the battery, and the grid simultaneously. This setup is crucial because it allows you to add the battery component easily at any point in the future without needing to replace your main inverter.
How can I monitor the battery's performance and usage?
Once your battery (or battery-ready system) is connected, you can monitor your solar generation, energy storage, and home usage in real-time. This is typically done through a dedicated phone app provided by the inverter manufacturer and can also be tracked via your electricity account.
