Commercial 3-Phase Inverters

Power large-scale solar installations with Rocksolar's commercial three-phase inverters, built for businesses, industrial facilities, and other high-demand applications. This collection ranges from an 18kW all-in-one hybrid unit up to Sol-Ark's 60kW three-phase system, giving you options across a wide span of commercial power requirements.

Most models here support hybrid operation, combining grid-tie and off-grid capability so a facility can draw from solar, battery storage, or the utility grid as needed. The WIT 28kW inverter adds AC-coupled hybrid storage compatibility, making it straightforward to pair with an existing battery bank or add one down the road.

Built for the demands of commercial and industrial energy systems, these inverters are designed to deliver dependable three-phase power at the scale larger operations require.
