Enphase IQ Battery 5P review: price and specs for Scottish homes
Last updated: 30 October 2026 · Reviewed by the Scottish Energy Efficiency team
Is the Enphase IQ Battery 5P worth it in Scotland?
The IQ Battery 5P is the simplest way to add storage to almost any existing solar system, because it is AC-coupled and leaves your current inverter alone. Its 15-year warranty is among the longest here. Each unit holds only 5kWh at 3.2kW, so the price per kWh is high for bigger systems.
