The Growatt WIT 28-55K-HU-US L2 is a high-performance three-phase hybrid inverter engineered for commercial and industrial (C&I) applications,as well as microgrid projects.This powerful and scalable solution supports system configurations up to 165kW by connecting up to six units in parallel,making it ideal for businesses with growing energy demands.
This inverter is designed for 208V/220V split-phase US grid standards and features a robust IP66/NEMA 4X enclosure for reliable outdoor installation.Built-in UPS functionality and black start capability ensure seamless backup power in the event of a grid outage,providing uninterrupted operation for critical loads.
Commercial and industrial solar storage projects
Microgrids and off-grid systems
Factory, warehouse, and campus backup power
Unbalanced load scenarios requiring 100% three-phase output
Built-in UPS function supports seamless <10ms switchover to battery power during grid failure.Black start allows the system to restart independently without grid support
Supports up to 6 units in parallel, extending total power from 28kW up to 165kW to match growing business needs
IP66/NEMA 4X enclosure provides protection against dust,water,and harsh environmental conditions,suitable for outdoor installation
Capable of fully powering unbalanced loads across three phases,making it suitable for applications with single-phase loads on different phases
Features DC/AC ratio up to 2.0 and max.efficiency of 98.2%,maximizing energy harvest from PV modules
Remote control of diesel generator (DG) enables automatic start/stop, reducing fuel consumption and manual intervention
