Huawei Sun2000-115KTL
The Huawei SUN2000-115KTL-M2 is a robust 115 kW three-phase transformerless string inverter engineered for large-scale solar installations across West Africa, the Sahel, and ECOWAS regions. Its 10 independent MPPT trackers and string-level management optimize energy harvest in high-irradiance environments, while smart I-V curve diagnosis enables rapid fault detection—critical for remote and off-grid solar projects. With 98.8% maximum efficiency and IP66 protection, this inverter withstands extreme heat, sand, and dust exposure, making it ideal for rural electrification and microgrid deployments that require long-term energy independence and minimal maintenance in harsh West African conditions.
