10kW Solar Battery Price

As more Australians turn to energy storage to cut electricity bills and avoid blackouts, the demand for larger solar batteries is on the rise—especially in high-usage homes and small businesses. A 10kW solar battery strikes a balance between robust storage capacity and manageable size, making it a popular choice for households aiming to maximise self-consumption from their rooftop solar.

In 2025, a 10kW solar battery in Australia can start from as low as $3,700, based on Solar National’s latest pricing—significantly more accessible than in previous years. While the final cost can vary depending on the battery brand, installation complexity, and available rebates, this lower entry point makes solar storage a viable upgrade for more Sydney homes than ever before.

What Is a 10kW Solar Battery?

A 10kW solar battery refers to a battery system capable of storing up to 10 kilowatt-hours of energy. In practical terms, this capacity is enough to power essential household appliances during the evening or in the event of a blackout, especially for medium to large-sized homes with solar panels. It’s commonly paired with a 6.6kW to 13kW solar system, depending on daily energy needs and expected self-consumption.

The battery doesn’t just store excess solar power—you can also program it to draw from the grid during off-peak times and use it during peak tariff hours. This strategy can substantially lower your energy bills in states like NSW, where time-of-use tariffs apply.

A 10kW solar battery typically supports:

• Evening electricity use for a 4–5 person household
• Running a pool pump, air conditioner, or EV charger
• Basic backup power during blackouts (if hybrid/inverter-compatible)

It’s important to note that 10kW refers to storage capacity (kWh), not output. Many batteries have power output limits between 3kW to 5kW continuous, which affects how many devices they can run simultaneously. Read More...
