Like Enphase rooftop microinverters, IQ batteries utilize a distributed architecture to provide maximum reliability. Each backup battery contains multiple IQ microinverters that switch energy from DC to AC and back again for safe and reliable operation. So even if a battery fails, the power keeps flowing and the lights keep shining.

Growing up was never this easy Enphase IQ Batteries are built on a distributed architecture platform. This modular microinverter design means you can quickly and easily expand the system as energy needs grow. It is very easy to expand the system with up to 12 batteries on the same installation.

Not all battery technologies are created equal Lithium Iron Phosphate (LFP) technology is simply safer. Our batteries use cobalt-free LFP chemistry that outperforms other battery technologies at high temperatures, reducing the risk of fires due to thermal stress.

Easy installation and service IQ Batteries are now officially approved for installation with both single and three phase third party inverters.

Replace microinverters in the field for quick repairs No need to return the entire battery. IQ Batteries uses IQ8 Series Microinverters that can be replaced in minutes.
