Trio Grand Series 120-136 kW On-Grid Inverters
High-capacity three-phase string inverters with eight MPPT trackers, 1100 V PV input, intelligent cooling and comprehensive grid protection.
Full Product Description
The Trio Grand Series is the highest-capacity on-grid family on the official category page, covering 120 kW to 136 kW. Eight MPPT trackers and eight groups of four string inputs provide detailed array segmentation for expansive industrial rooftops and ground-mounted plants. High conversion efficiency, 1100 V PV input, IP65 protection, intelligent air cooling and integrated grid and surge safeguards support high-output installations that demand scalable string management.
Key Features
