Enphase Energy was established in 2006 in Fremont, California, and entered the battery market in 2016. The company's batteries use safe lithium iron phosphate (LFP) chemistry, emphasizing modularity and AC-coupling, which lets a battery sit alongside an existing solar system, with a datasheet AC round-trip efficiency of 90% for the IQ Battery 5P. In WA, adding a battery to an existing system counts as an alteration under the connection rules, so an AC-coupled addition is worth comparing against a hybrid inverter replacement. Enphase has a Melbourne office in Australia and supports installations through certified installers, providing local technical assistance. The Enlighten monitoring platform provides panel-level data. The systems offer backup capability and scale to 60kWh with multiple units. Warranties extend to 15 years or 6,000 cycles with 60% capacity retention, reflecting confidence in the product's longevity amid Australia's harsh sun exposure.
