An off-grid battery system stores excess solar energy generated by your solar panels to be used during times when the sun isn't shining, providing reliable power even when disconnected from the grid.

An on-grid battery system, also known as a grid-tied battery system, works in conjunction with your existing grid-connected solar panels. It stores excess solar energy and can supply power during peak demand or grid outages, while also allowing you to feed excess energy back into the grid for credits or compensation. This system provides a balance between energy independence and the benefits of grid connectivity.

An off-grid battery system typically consists of solar panels, inverters, and batteries. Solar panels convert sunlight into electricity, which is then stored in batteries as DC power. Inverters convert DC power to AC power for use in your home.

Off-grid battery systems offer energy independence, reduced reliance on the grid, lower electricity bills, and the ability to have power during grid outages or in remote locations.

The size of your battery storage system depends on your energy consumption, solar panel output, and the duration of backup power you require. Our network of approved solar installers can help you determine the appropriate size.

The duration of power depends on the capacity of the batteries, your energy usage, and whether it is an on grid or off grid set up. On grid battery systems typically offer a few hours of back-up power, while a Guardian Series Battery System is designed to provide off grid back-up power for multiple days when solar panels are not generating power due to inclement weather.

We recommend professional installation to ensure safety and optimal system performance. Our certified installers have the expertise to set up your system correctly.

Our off-grid battery systems utilise environmentally friendly and recyclable materials. The Polarium battery modules utilised in the Guardian Series are designed with safety features to prevent issues like overcharging and overheating.

Battery lifespan varies based on factors such as usage patterns, temperature, and maintenance. Solar Energy Australia only uses premium Polarium battery modules that can last anywhere from 10 to 20 years.

Yes, you can add more solar panels to increase your energy production, along with additional Guardian battery system cabinets to increase storage capacity as your needs change.

Your off-grid system will store excess energy from sunny days to use during cloudy periods. However, extended overcast conditions might reduce the amount of power available. Your solar installation expert can provide recommended solutions to ensure your off-grid system always provides power.

Your solar installer will provide an agreed maintenance schedule to ensure your battery system provides years of reliable power storage.

Yes, some off-grid systems can be integrated with generators to provide additional backup power during extended periods of low sunlight or high energy demand.

Incentives can vary by location. Check with local authorities or visit relevant government websites to learn about potential rebates, tax credits, or grants for installing off-grid solar and battery systems.
