Most standard solar PV systems come with an inverter that converts DC (direct current) electricity—produced by your solar panels—into AC (alternating current) electricity, which powers your home and feeds into the National Grid. However, this setup doesn’t include energy storage. Any energy not used immediately is exported back to the grid.
That’s where solar batteries come in.
They store excess solar energy generated during the day so you can use it in the evening or during peak demand times—when electricity rates are typically higher. This helps to significantly lower your electricity bills and increase your energy independence.
But solar batteries aren’t just a financial investment—they’re a step towards a more sustainable lifestyle. By storing and using your own solar energy, you reduce your reliance on fossil fuels, lower your household carbon emissions, and contribute to a cleaner, greener future.
