Enphase launches IQ Battery C80 for commercial sites
Estimated reading time: 4 minutes · Last updated:
Enphase Energy has opened U.S. pre-orders for the Enphase IQ Battery C80, its first energy storage platform built for commercial and industrial customers. The modular unit provides 80 kWh usable capacity and a distributed, microinverter-based power conversion capable of 40 kVA continuous AC output and a motor-starting surge of 143.3 A LRA. Shipments are expected to begin in Q1 2027, and the system carries a 15-year or 7,000-cycle warranty. As first reported by pv magazine USA, the IQ Battery C80 targets schools, retail, offices and logistics warehouses and supports 277Y/480 V and 120Y/208 V site interconnections.
Key takeaways
- The IQ Battery C80 uses an 80 kWh usable capacity modular block with microinverter-based conversion and ships preassembled for commercial sites.
- The system delivers up to 40 kVA continuous AC power, a peak output current of 96 A and a motor-starting surge capability of 143.3 A LRA.
- Enphase rates the AC-to-AC round-trip efficiency as exceeding 90% and backs the product with a 15-year or 7,000-cycle warranty.
- Shipments are expected to begin in Q1 2027 and the enclosure is an outdoor NEMA 3R unit measuring 78.7 by 36.2 by 31.5 inches.

How the IQ Battery C80 is built and what it delivers
Enphase designed the IQ Battery C80 around an 80 kWh usable capacity modular building block and a distributed, microinverter-based power conversion architecture. The microinverter approach places power conversion at module level, allowing the system to present up to 40 kVA of continuous AC power to the site and to support both 277Y/480 V and 120Y/208 V interconnections depending on grid configuration.
The platform provides a peak output current of 96 A and a motor-starting surge capability specified at 143.3 A LRA. Enphase reports AC-to-AC round-trip efficiency exceeding 90% and says the unit ships factory-assembled to reduce on-site DC wiring and internal module stacking during installation.
Safety, enclosure and thermal management
The IQ Battery C80 uses lithium iron phosphate cells with active, module-level thermal controls and smart forced-air cooling plus module heaters rather than liquid cooling or dedicated HVAC. That design aims to lower parasitic power draw and reduce long-term maintenance demands on commercial rooftops and small yards.
Safety features listed by Enphase include UL 9540A-tested thermal runaway mitigation, module-level smoke and gas detection, active pressure relief and an integrated aerosol fire suppression system. The product ships in a floor-mounted outdoor NEMA 3R enclosure measuring 78.7 inches by 36.2 inches by 31.5 inches with front-access service routing for tight footprints.
Commercial fit, warranty and tax policy implications
Enphase positions the IQ Battery C80 for commercial and industrial customers such as schools, retail locations, offices and logistics warehouses, and integrates the battery with its energy management software for self-consumption optimization, demand charge reduction, time-of-use arbitrage and VPP participation. The platform’s preassembled form and AC coupling are meant to simplify installs on those site types.
The system is designed in the United States and, Enphase says, complies with FEOC guidelines and targets domestic content to enable commercial tax equity investors and project owners to qualify for bonus adders under the ITC. The battery carries a 15-year or 7,000-cycle warranty and Enphase has opened U.S. pre-orders ahead of shipments in Q1 2027.
What could move this either way
The case for
- Factory-assembled, AC-coupled design should cut on-site labor and accelerate commercial deployments where three-phase interconnection is available.
- Targeted domestic content and FEOC compliance may allow projects to capture ITC bonus adders, improving commercial project economics where tax equity structures apply.
The case against
- Actual cost and lead times are not disclosed; without pricing the speed of customer uptake is uncertain for budget-constrained municipal or school projects.
- Qualification for ITC bonus adders depends on verification of domestic content and investor structures, which can be complex and vary by project.
What to be careful about
- Price per unit and total installed cost are not provided, exposing project budgets to unknown equipment expense.
- The claimed AC-to-AC efficiency exceeding 90% and motor-start surge numbers lack third-party field data at commercial scale.
- ITC bonus adder eligibility depends on demonstrable domestic content and tax equity structures, which some buyers cannot use.
The bottom line
The IQ Battery C80 places Enphase into the commercial energy storage space with a factory-assembled, AC-coupled product that targets multi-megawatt-hour scale deployments through modular 80 kWh blocks. Key published specs — 40 kVA continuous output, 96 A peak current, a 143.3 A LRA motor-start capability, AC-to-AC efficiency exceeding 90% and a 15-year or 7,000-cycle warranty — address the operational needs of schools, retail and logistics sites. Missing from the announcement are price, exact domestic content percentages and shipment cadence; those factors will determine how quickly project owners adopt the platform after the planned Q1 2027 start of shipments.
What to watch
- Watch for shipments to begin in Q1 2027 and for initial delivery volumes and lead times to be announced; Enphase expects shipments in Q1 2027.
- Watch for the first commercial installations—schools, retail or warehouses—to publish performance data; no date has been set.
