Three-Phase String Inverter · 25-30 kW
MID 25-30KTL3-X2 (Pro.E) Three-Phase String Inverter
Models: MID 25KTL3-X2 (Pro.E) / MID 30KTL3-X2 (Pro.E)
A three-phase string inverter platform for commercial and industrial rooftop PV. The 25 kW and 30 kW models use three MPPT inputs in a 2+1+1 string configuration, with a 200-1000 V operating range, 1100 V maximum DC input voltage and IP66 protection. A 20 A string current design, smart air cooling and flexible monitoring support high-current modules and varied roof layouts.

Product Overview
The MID 25-30KTL3-X2 (Pro.E) series covers 25 kW and 30 kW three-phase models. Both use three MPPT inputs in a 2+1+1 string configuration, with a 200-1000 V MPPT operating range and 1100 V maximum DC input voltage. The 20 A string current design supports high-current modules and flexible string layouts.
The platform uses smart air cooling and an LED display with WiFi and APP monitoring. Maximum efficiency is 98.75% for the 25 kW model and 98.8% for the 30 kW model; China efficiency is 98.6% and MPPT efficiency is 99.9%. The IP66 enclosure is suitable for outdoor installation.
