Collection: Industrial & Commercial AC-coupled three phase Inverters

Scale your commercial or industrial solar system with AC-coupled three-phase inverters built for facilities that need more than a residential-grade unit can deliver. This collection starts at 20kW with the Isuna U20K-PH — a split-phase, high-voltage hybrid inverter with SiC (silicon carbide) technology and four MPPTs for flexible array wiring across 120V/240V/208V output — and scales up to the Sol-Ark 60kW three-phase hybrid inverter, which runs on 480V three-phase output and supports simultaneous AC and DC coupling for integrating with existing infrastructure or a new build.

The Sol-Ark 60kW is also paired here with its matching Commercial Energy Storage System: a UL9450-certified, cobalt-free LiFePO4 battery bank with 61.44kWh of capacity, a 614.4V high-voltage architecture that reduces energy losses over long cable runs, and a 19" rack-mount design for standard electrical rooms. Both 60kW units are expandable via parallel connection, so capacity can grow with your facility's load rather than requiring a full replacement down the line. AC coupling in this range is particularly suited to retrofits — adding storage or backup to a facility that already has solar or grid infrastructure in place, without redesigning the DC side of the system.
