The all-in-one, AC-coupled system will deliver 80 kWh of usable energy capacity and up to 40 kVA of continuous power in a single, compact enclosure, with battery packs and microinverters fully integrated. <a href="https://www.globenewswire.com/Tracker?data=YUa7w3KGxWXmrDYzlffeCO9e14rUnM6K5GJ5Y1xcnuwq3WalonOViiVmtkYFttpjMiBMAlQjKC4TWa42JmnraHi6XS0BsuiIuo654RGZl2OYgA3GfHaH1xv2frMDP_sNSTcWlPDx1r5XBhZzKsKPaw==" rel="nofollow" target="_blank" title="IQ Battery C80">IQ Battery C80</a> extends Enphase's distributed architecture into commercial energy storage, completing the company's end-to-end commercial offering. It will pair with IQ9N-3P™ and IQ9S-3P™ Commercial Microinverters at 277Y/480 V, as well as IQ8P-3P™ and IQ8H-3P™ Microinverters at 120Y/208 V, enabling complete, all-AC solar-plus-storage systems without central inverters or high-voltage DC coupling. From 80 kWh to 2 MWh, the system is engineered for commercial, industrial, and multifamily applications. Its modular architecture will allow customers to right-size projects and expand storage capacity over time. Its distributed, microinverter-based architecture is designed to reduce single points of failure and support high system uptime. IQ Battery C80 will support demand charge management, time-of-use shifting, solar self-consumption, grid services, and virtual power plant (VPP) participation — helping customers manage energy costs and maximize the value of onsite solar generation. IQ Battery C80 will be available in two three-phase configurations: a 120Y/208 V model delivering 33 kVA for multifamily properties and smaller commercial buildings, and a 277Y/480 V model delivering 40 kVA for larger commercial and industrial applications. Both will use lithium iron phosphate (LFP) chemistry, deliver greater than 90% AC round-trip efficiency, and operate across an ambient temperature range of -22°F to 131°F. Both configurations will support Enphase Power Control software, certified to UL 3141, enabling two-hour or four-hour system designs. Busbar and feeder overload controls will enable flexible wiring, help reduce balance-of-system infrastructure costs, and potentially avoid unnecessary electrical equipment upgrades. The AC-coupled architecture will also allow IQ Battery C80 to pair with third-party commercial three-phase solar inverters for both new and retrofit projects. IQ Battery C80 will use active air cooling without liquid cooling or external HVAC, helping simplify installation and improve reliability. Its integrated battery and power-conversion architecture will also reduce the number of separate components that need to be installed and interconnected. Battery-module-level heating will support reliable operation in cold-weather conditions. IQ Battery C80 is expected to be produced at U.S. manufacturing facilities and to be FEOC compliant. U.S. production can also help certain eligible projects qualify for domestic content bonus tax credits, subject to project-specific requirements and applicable laws. Safety is engineered at the module level. IQ Battery C80 will feature battery-module smoke and gas sensing with active pressure release, along with support for fire alarm control panel integration and emergency stop for safe isolation. The system will be certified to UL 9540A and large-scale fire test protocols for thermal runaway safety and housed in an outdoor-rated NEMA 3R enclosure for pad or floor mounting. “We designed the IQ Battery C80 to make commercial storage simpler to deploy, easier to scale, and more resilient,” said Aaron Gordon, senior vice president and general manager of the systems business unit at Enphase Energy. “With 208 V and 480 V configurations, it will serve applications ranging from multifamily properties to large commercial and industrial facilities.” Pre-orders for the IQ Battery C80 are open now, with shipments expected to begin in the first half of 2027. The system will be backed by a 15-year limited warranty. Customers should consult their legal and tax advisors to confirm eligibility for applicable tax credits and incentives.
