5kWh Solar Batteries

A 5kWh solar battery is a compact and powerful solution designed for Australian homes and small businesses aiming to reduce electricity costs, increase energy independence, and gain battery storage flexibility. With a usable capacity of 5 kWh, these home batteries such as those available through our solar battery range store excess solar power generated during the day for use at night or during grid outages.

Solar Galaxy supplies CEC Certified systems using trusted batteries in Australia, including the reliable BYD battery range. A 5kWh system is ideal for properties that typically consume moderate amounts of energy, making it suitable for essential load support, backup, and off-grid or hybrid inverter configurations. With access to the 2025 federal rebate, you can save up to $1,860 on your installation.
