Details
The Solplanet ASW333K-HT is a high-capacity 333kW three-phase solar inverter designed for utility-scale, commercial and industrial solar PV systems. Built for EPC contractors, professional solar installers, solar wholesalers and solar PV suppliers, this inverter delivers high conversion efficiency, advanced protection and intelligent operation for large photovoltaic projects. With 1500V DC system architecture, 500–1500V MPPT voltage range, 6 independent MPPTs and 75A per MPPT, the ASW333K-HT is compatible with modern high-current solar panels, bifacial modules and large-area PV arrays. Its 333000VA AC output at 40°C, 99.01% maximum efficiency and 98.52% European efficiency help reduce LCOE and maximize long-term energy yield. The inverter includes IP66 protection, smart forced cooling, PV string monitoring, AC/DC temperature detection, Type II DC and AC surge protection, RCMU, ground fault monitoring, grid monitoring, anti-islanding protection and optional Anti-PID. With RS485/ABUS communication, Bluetooth APP display and smart remote diagnostics, it is a professional solar inverter solution for large complete solar kits and demanding solar PV power plants.
