The Homeowner’s Guide to Enphase Batteries

Written By Linden Stone

Thinking about adding a battery to your solar system? If you’ve been researching your options — or chatting to installers — you’ve probably come across the Enphase IQ Battery.

So, what makes Enphase stand out?

Let’s break it down — simply, clearly, and without the jargon.

What Is an Enphase Battery?

The Enphase IQ Battery is a modular lithium-iron phosphate (LFP) storage system designed to work seamlessly with Enphase microinverters and the Enphase Energy System. It's smart, safe, and designed with full-grid interaction in mind — so you can charge, store, and discharge power exactly when it makes most sense (and saves you the most).

What Makes Enphase Different?

Here’s what we think makes Enphase worth a serious look — especially for homes in the South West UK:

Fully modular and scalable

Start with a single 5kWh and add more as your usage grows. Perfect for staged upgrades.

Excellent blackout protection

Pair with an Enphase system controller and you can keep the lights (and WiFi) on during outages. Grid stability isn’t always guaranteed — even in towns like Frome and Gillingham.

Built-in safety

Using lithium-iron phosphate means better thermal stability, and Enphase’s design is low-voltage and inherently safer for domestic settings.

Smart energy management

Use the Enphase app to see how much you’re generating, storing, and using — in real time. You’re in control.
