Huawei SUN2000-115KTL-M2 — 115 kW three-phase Smart PV Controller / string inverter with 10 MPPTs, IP66 protection, smart string-level management and up to 98.8% peak conversion efficiency.
Availability: In Stock
he SUN2000-115KTL-M2 is a heavy-duty commercial/utility string inverter designed for medium and large rooftop or ground-mounted PV plants. It delivers 115 kW nominal AC power (up to 125 kVA apparent), supports 10 independent MPPTs and up to 1,100 V DC input, and is built for harsh outdoor environments (IP66). The unit emphasizes high energy yield (98.6–98.8% peak efficiency), safety (arc-fault protection, residual current monitoring, DC/AC surge arresters) and smart O&M through FusionSolar monitoring and string-level diagnostics.
