A solar battery stores unused energy generated by your panels during the day, allowing you to use it later — for example, in the evening or during a power cut. This reduces your reliance on the grid and helps you make the most of your solar system. (Emergency backup is only available if the system includes an EPS switch that enables the battery to operate in island mode)
Not all batteries do, it depends on the system. If backup power is important to you, we’ll recommend a model with this capability and ensure it’s installed with the correct wiring
Yes. Most systems can be retrofitted with a battery, either connected to the DC side (before the inverter) or AC side (after the inverter). We’ll assess your system to recommend the best setup
Costs vary depending on size, brand, and features. Typical home batteries start from around £3,000–£5,000, while larger capacity or premium models cost more. We provide tailored recommendations based on your home’s usage and energy goals
