Commercial energy management

The Growatt WIT commercial hybrid inverter manages power between the solar array, high-voltage battery system, utility grid, generator and connected loads.

Programmable operating strategies can support:

• Solar self-consumption
• Peak-demand management
• Time-of-use energy shifting
• Battery backup
• Generator-assisted operation
• Export control
• Commercial microgrid applications
• EV-charging load management

During a utility outage, the inverter can transfer selected loads to backup operation in 10ms or less. Its 100% unbalanced-load capability allows different power levels to be supplied across the three phases, subject to the inverter’s total output limits.

• Warehouses and distribution centres
• Manufacturing facilities
• Farms and agricultural operations
• Hotels and commercial buildings
• Schools and institutional facilities
• Commercial EV-charging stations
• Solar carports
• Generator-supported microgrids
• Peak-shaving battery systems
• Critical-load backup systems
