Product Overview
The MOD 8-15KTL3-X2 (Pro) series covers four three-phase power classes: 8 kW, 10 kW, 12 kW and 15 kW. All models use a dual-MPPT architecture with a 140-1000 V MPPT operating range and a 600 V rated input voltage, giving designers flexibility when strings face different orientations or shading conditions.
Each model shares the same compact enclosure, natural cooling and transformerless topology. Maximum efficiency is 98.6%, MPPT efficiency is 99.9%, and Type II surge protection is provided on both the DC and AC sides. The inverter is rated IP66 for outdoor installation and supports optional WiFi, GPRS, 4G or LAN monitoring.
