Huawei SUN2000-115KTL-M2 Three-Phase Inverter 115 kW, Type I+II DC SPD

The SUN2000-115KTL-M2 is Huawei's workhorse for commercial and industrial PV between roughly 100 and 150 kWp per unit. Ten independent MPP trackers with two inputs each let one inverter handle roofs with several orientations, and every string is monitored, so a failing string or connector shows up in FusionSolar instead of hiding in the total. Smart I-V curve diagnosis checks the whole array remotely, which replaces most manual string testing. The design is fuse-free, cooled by smart air cooling and sealed to IP66, and it communicates over RS485 or MBUS on the AC cable. This variant adds Type I+II DC surge arresters, which installers specify where the array or building has external lightning protection.
