One system — and you already own half of itAn Enphase Energy System is made up of panels, each with their own microinverter, a battery, and smart control working as one. You’ve got the first half. Adding IQ Batteries allows you to store your solar and leverage it with advanced energy management to maximise your savings and reduce your reliance on the grid. Claim energy independence |
Meet the IQ Battery 5P with FlexPhaseThe IQ Battery 5P with FlexPhase works seamlessly with single- or three-phase homes and scales one 5 kWh unit at a time. Each unit gives you real power to run your home — not just storage you’ll never use — and is built to keep delivering for 15 years and 6,000 charge cycles: the market’s leading warranty, and lifetime energy roughly double what many rivals guarantee.

See how PowerMatch gets more out of every stored kilowatt-hour. What is PowerMatch technology?Most batteries run one big inverter all night — even when your home is barely drawing power — and waste energy doing it. The IQ Battery 5P has six small inverters inside and turns on only as many as you need, like a modern car that shuts its engine off at the lights. So more of the energy you stored actually reaches your home: up to 40% more usable energy than a conventional battery.

Two rebates, not oneThere are an endless selection of home batteries on the market but Enphase is different. With IQ Batteries you don’t get one rebate — you get two. One comes from the government. The other is engineered into the battery itself.

Frequently Asked QuestionsRight now your surplus solar earns just a few cents when it’s exported, but costs 30–45c to buy back after dark. A battery closes that gap: every kWh you store and use yourself is worth far more than one you sell. And because an Enphase battery is warranted for 15 years, not 10, it keeps returning that value years after cheaper batteries stop — which is what makes the lifetime maths so attractive. A 15-year warranty where most stop at 10, with 60% capacity still guaranteed at year 15 — and two decades of Enphase honouring its promises behind it. Enough to cover your evening and overnight use — not your whole day. Oversizing just adds cost for storage you’ll never draw on. The IQ Battery 5P is modular, so we size it to how your home actually runs, and you can add more of the same unit any time. With the IQ System Controller added, yes. Selected circuits — lights, fridge, internet — switch to backup automatically the moment the grid drops, and your solar keeps refilling the battery each day so you’re covered through longer outages. Yes — single-phase or three-phase. As one Enphase system, the battery and your existing microinverters talk to each other, so you store your surplus instead of exporting it for cents. |
