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

• Five power options from 120 kW to 136 kW
• Eight MPPT trackers
• Four strings per MPPT group
• 1100 V maximum PV input
• Up to 98.8% maximum efficiency
• Type II DC and AC surge protection
• IP65 construction and intelligent air cooling

Recommended Applications

• Large industrial rooftops
• Solar farms and ground-mounted plants
• Manufacturing campuses
• Projects requiring eight independently tracked PV groups

Model Selection Guidance

Grand is appropriate when project scale and array diversity justify eight MPPT groups. Final selection should follow the grid connection limit, permitted apparent power and the array's 40 A-per-channel operating-current design.
