Huawei Sun2000-330KTL
The Huawei SUN2000-330KTL-H1 is a robust 330 kW smart string inverter engineered for utility-scale and large microgrid solar projects across West Africa, the Sahel, and beyond, delivering exceptional performance in high-irradiance and extreme-temperature conditions. With transformerless topology achieving up to 99.03% maximum efficiency, six MPPTs, and wide voltage range compatibility, it enables flexible system design for off-grid and grid-connected rural electrification initiatives across ECOWAS regions. Built to withstand dusty, corrosive environments typical of Mauritania and the Sahel, the inverter features IP66 protection, C5-Medium anti-corrosion rating, and intelligent diagnostics including Smart String-level Disconnection and Smart IV Curve Diagnosis for reliable energy independence in remote locations.
