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.

We only work with reliable, high-quality manufacturers. For battery-ready systems, we primarily install hybrid inverters from trusted brands like Fronius and GoodWe. When our clients are ready to install batteries, we partner with reliable storage solutions, including modules from companies like Risen, Fronius & GoodWe to ensure seamless integration.
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.
A battery-ready system uses a hybrid inverter (like those from Fronius or GoodWe) 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.
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 (e.g., Fronius Solar.Web) and can also be tracked via your electricity account.
