Enphase Energy Strengthens Battery Storage Footprint Globally

Enphase Energy, Inc. (ENPH) continues to make significant strides in the global battery storage market, building on its position as one of the leading providers of fully integrated solar-plus-storage solutions. In the second quarter of 2025, the company shipped 190.9 megawatt-hour (MWh) of IQ Batteries, reflecting an impressive 58.8% year-over-year growth. This robust performance highlights the strong demand for Enphase Energy’s battery products.

Enphase Energy currently ships its third-generation IQ Battery 5P to a wide range of global markets, including the United States, Australia, New Zealand, Puerto Rico, Mexico, Canada, the United Kingdom, Italy, France, the Netherlands, Luxembourg, Belgium, Romania and India. The company recently broadened its European footprint by introducing the IQ Battery 5P with FlexPhase for customers in Germany, Austria, Switzerland, Luxembourg, Poland, Spain, Portugal, France, the Netherlands, Belgium, Sweden, Denmark, Greece, Croatia, Slovenia, Romania and Slovakia.

Additionally, in August 2025, the company launched the IQ Battery 5P with FlexPhase for customers in Australia. In June, Enphase Energy began shipments of its fourth-generation IQ Battery systems in the United States, while simultaneously advancing its fifth-generation IQ Battery. The upcoming product is expected to deliver 50% higher energy density along with significant cost reductions, a move that could further enhance ENPH’s competitive edge in the fast-growing battery storage market.
