Trio Zen Series 40-50 kW On-Grid Inverters
The Trio Zen Series targets larger commercial and industrial PV arrays with 40 kW, 45 kW and 50 kW options. The 40K and 45K models use three MPPT trackers, while the 50K expands to four, supporting diversified roof planes or string groups. A 1100 V maximum PV input, high conversion efficiency, IP65 construction, intelligent air cooling and comprehensive monitoring and protection functions make the series suitable for high-yield grid-connected projects.
Key Features
- 40 kW, 45 kW and 50 kW options
- Three MPPT trackers on 40K and 45K; four on 50K
- 1100 V maximum PV input
- Up to 98.7% maximum efficiency
- Zero-export application support
- Intelligent air cooling
