Description

Product Description

The Sungrow 36 kW PV Inverter (model SG36CX-P2 / SG36CX-US) is engineered for medium-to-large grid-connected solar systems such as commercial rooftops, factories, and ground-mounted arrays. It supports up to four independent MPPT inputs, allowing efficient energy extraction from multiple PV string configurations even under shading or mismatched conditions. The inverter features high conversion efficiency, advanced safety protections including arc fault circuit interruption (AFCI), surge protection, grid monitoring, and rapid shutdown functions. Monitoring and communication options include RS485, Bluetooth, and optional Wi-Fi or Ethernet for remote system visibility and diagnostics. Its robust design with smart forced-air cooling and IP66/C5 protection makes it suitable for outdoor environments and long-term reliable operation.
