Ireland's Trusted Battery Storage Installer

Why More Irish Homeowners Are Adding Battery Storage in 2025

As energy prices remain unpredictable and solar adoption continues to grow, Irish homeowners are turning to battery storage to maximise their energy independence. By storing excess solar power for use at night or during peak-rate hours, battery systems are helping thousands of homes cut electricity bills even further.

Battery storage also lets you take advantage of cheap night-rate electricity. Allowing you to charge your battery from the grid at off-peak times and use that stored energy during the day when rates are higher. It’s a smart way to boost savings, even on cloudy days.

From Dublin to Cork, battery storage is becoming a must-have upgrade for households that want to make the most of their solar investment, protect against grid outages, and reduce reliance on fossil fuels.

At WattCharger, we make adding battery storage simple and stress-free. Our expert team will assess your home’s solar generation, energy usage, and goals to recommend the right system. Whether you're retrofitting an existing solar setup or starting fresh.

With SEAI-registered professionals, tailored solutions, and seamless installation, WattCharger ensures you get the most from your energy, day and night.

Smart Battery Storage Solutions, Seamlessly Installed

At WattCharger, we install market-leading home battery storage systems designed to help Irish homeowners take control of their energy usage. Whether you already have solar panels or are planning a new installation, adding a battery lets you store excess electricity for when you need it most. At night, during power cuts, or when energy prices peak.

Maximise Your Solar Investment

Battery storage transforms how you use energy. Instead of sending surplus solar power back to the grid, you can store it on-site and use it later. Powering your home, EV, or even essential appliances during outages. It’s also ideal for charging at night using cheaper off-peak electricity, helping you reduce costs even on cloudy days.
