Domestic Solar Battery Installation: Hybrid Battery Storage Solutions

With fuel costs rising at an average of 7.04% per year, according to ONS data, hybrid solar battery systems offer an excellent way to protect your household from energy price hikes. A hybrid inverter replaces the traditional solar inverter, prioritising the use of solar energy within your home and storing excess energy in batteries for later. Once your batteries are fully charged, any extra energy can be sold back to the grid for a small financial return.

During the day, while most people are out at work or school, the sun is shining, and your solar panels are generating energy. Hybrid battery systems capture and store that energy for when it’s needed most—when your family is home in the evening—helping you save even more money on your energy bills.

Additionally, many energy suppliers now offer Time of Use Tariffs, which means you can charge your batteries during cheaper night-time rates and use that stored energy during peak, more expensive times. This makes
hybrid solar battery storage a powerful tool for reducing your energy costs all year round.

Emergency Power Supply (EPS): Power When You Need It Most

With an Emergency Power Supply (EPS) system integrated into your solar battery storage, you can rest assured that your essential circuits—such as lighting, your fridge, and your WiFi—will continue to function during a power cut. This optional feature allows for automatic or manual changeover in case of grid failure, ensuring continuous power to your most vital systems.

EPS works alongside your hybrid solar inverter to charge your batteries and continue supplying solar energy during daylight hours, even when grid power is unavailable. However, it’s important to note that EPS can only power devices as long as there is stored energy in the batteries. While it’s not designed to power the entire household, EPS is ideal for maintaining critical functions during outages.

AC Coupled Battery Solutions: Flexibility for Existing Solar PV Systems

If you already have a Solar PV system with micro-inverters installed, AC coupled battery solutions offer a flexible, retrofit option for energy storage. These systems work independently of your existing solar equipment, meaning they can be installed in a separate location from your Solar PV array. Whether you’re looking to upgrade your system or have participated in the Rent-a-Roof scheme, AC coupled batteries allow you to store excess solar energy for use when it’s needed.

AC coupled systems provide the same benefits as hybrid battery systems, giving you the flexibility to store and use solar energy even if you’re not at home during the day.

How Does a Solar PV System Work?

Solar photovoltaic (PV) systems capture daylight energy using silicon cells, converting it into electricity that can be used to power your home. The inverter transforms this energy into alternating current (AC) electricity, ready for immediate use. Any excess energy can be stored in a battery for later use or fed back into the national grid.

A generation meter tracks how much electricity your system produces, while a Smart Export Guarantee (SEG) scheme can pay you for any surplus energy you send to the grid. SEG tariffs vary between providers, so it’s worth shopping around for the best rate. For homeowners who aren’t home during peak solar generation hours (10am–4pm), adding an energy storage solution—such as a battery or even an immersion controller to heat your water—ensures you make the most of your solar power.

Electric vehicle (EV) owners can also charge their cars using solar energy, turning your home into an eco-friendly hub of energy efficiency.
