<div id="readability-page-1">FREMONT, Calif., May 18, 2026 (GLOBE NEWSWIRE) -- Enphase Energy, Inc. ( ENPH ) , a global energy technology company, today announced the launch of PowerMatch™ technology for IQ® Battery 10C™ systems in the United States, including Puerto Rico, and for IQ® Battery 5P™ systems across North America and select countries in Central America and the Caribbean. PowerMatch intelligently adjusts IQ® Battery operation to match a home’s real-time power needs, helping deliver more usable energy, improved efficiency, and long-term savings. Watch a video about how it works. All battery inverters deliver only the power required by the home at any given moment. The difference is how efficiently they deliver that power, especially at lower loads. In many hybrid string inverter systems, a single large inverter remains active even when the home is using only a small amount of power, which can reduce efficiency and waste energy. IQ Batteries use multiple embedded microinverters, allowing PowerMatch to activate only the number of microinverters needed to serve the home’s real-time load. This helps reduce idle conversion losses and lets homeowners capture more of the energy they store, particularly during the low-use hours that make up much of a typical day. Based on Enphase testing with the IQ Battery 10C, PowerMatch can reduce energy losses by up to 1 kWh per day for a typical California homeowner compared to certain hybrid string inverter-based battery systems. That translates to up to $2,000 in additional savings over the battery’s life, depending on system configuration, usage patterns, and regional tariffs. &#34;Most homes don't operate at peak demand very often and instead spend the majority of the day at lower, steady loads,&#34; said Jeremy Truitt, field engineer at Lighthouse Solar, an installer of Enphase products in the United States. &#34;PowerMatch reduces standby energy consumption by operating just the microinverters that best match the home's power needs at any given time. This helps minimize standby energy use while keeping the system ready for a backup event.&#34; &#34;PowerMatch is the kind of upgrade installers love to deliver,&#34; said Mike Sullivan, director of operations at NEC Electric &amp; Solar, an installer of Enphase products in the United States. &#34;It quietly makes existing systems more efficient by operating only the microinverters needed for the home's real-time load, which means more usable energy from the same battery. Our customers don't have to do anything, and they get more out of their investment.&#34; “PowerMatch reflects the power of Enphase’s distributed architecture,” said Aaron Gordon, senior vice president and general manager of the systems business unit at Enphase Energy ( ENPH ). “When intelligence is built into the system, software can make the hardware better over time — helping homeowners get more usable energy and more long-term value from the battery they already own.” PowerMatch launched in Europe last year for IQ Battery 5P systems, including batteries with FlexPhase™ technology. It is now available for IQ Battery 5P systems in the United States, Puerto Rico, Canada, Mexico, Bermuda, the Cayman Islands, the Bahamas, and Panama, and for IQ Battery 10C systems in the United States and Puerto Rico.
