Retrofit Battery Storage Without Replacing Your Solar
If you already have solar panels, an AC-coupled or hybrid battery lets you store surplus generation for evening use instead of exporting it cheaply to the grid. We assess your existing inverter, panel layout, and consumption to recommend a compatible battery.
- Works with most existing solar PV systems
- AC-coupled options avoid replacing your current inverter
- Hybrid upgrades available where a full refresh makes sense
- Store daytime solar for evening and peak-rate periods
- Optional backup power with supported systems
- Professional survey before we quote
