California-based energy technology provider Enphase Energy has announced the commercial launch and U.S. pre-order availability for the IQ Battery C80, marking the manufacturer’s first energy storage platform engineered specifically for commercial and industrial applications. Target deployments include schools, retail locations, commercial offices, and logistics warehouses. Shipments are expected to begin Q1 2027.
The unit arrives fully assembled from the factory to streamline installation and reduce site labor time, complexity, and installation risk. Installers connect external AC conductors to commission the unit, eliminating the need to perform internal module stacking, DC wiring, or field-installed power electronics integration.
Built on an 80 kWh usable capacity modular building block, the system features a distributed, microinverter-based power conversion architecture capable of delivering up to 40 kVA of continuous AC power. Depending on grid configuration, the three-phase system supports 277Y/480 V and 120Y/208 V site interconnections. The system provides a peak output current of up to 96 A, a motor-starting surge capability of 143.3 A LRA, and an AC-to-AC round-trip efficiency exceeding 90%.
The battery enclosure utilizes lithium iron phosphate chemistry paired with active, module-level thermal controls. By relying on smart forced-air cooling and module heaters instead of liquid cooling loops or dedicated HVAC equipment, the platform minimizes internal parasitic power consumption while lowering long-term maintenance requirements.
Safety compliance features include UL 9540A-tested thermal runaway mitigation, individual module-level smoke and gas detection, active pressure relief mechanisms, and an integrated aerosol fire suppression system.
The unit is housed in a compact, floor-mounted outdoor NEMA 3R enclosure measuring 78.7 inches by 36.2 inches by 31.5 inches, designed with front-access service routing for tight commercial footprints.
Designed in the United States, the system complies with FEOC guidelines and incorporates targeted domestic content, enabling commercial tax equity investors and project owners to qualify for bonus adders under the ITC, said Enphase.
The IQ Battery C80 is backed by a 15-year or 7,000-cycle warranty. The battery integrates with Enphase energy management software to perform self-consumption optimization, demand charge reduction, time-of-use arbitrage, and VPP participation.
