Sungrow SP1400D 1400W Dual Panel Power Optimiser (ASP00054)

Sungrow SP1400D 1400W Dual Panel Power Optimiser

The Sungrow SP1400D is a 1400W dual-panel power optimiser designed for commercial and industrial PV systems using compatible Sungrow CX-P2 inverters. Its 1:2 architecture connects two PV modules to one optimiser, providing module-level MPPT, rapid shutdown and precise fault diagnostics. The SP1400D helps maximise energy yield on PV systems affected by shading, module mismatch or different roof orientations.

With up to 23A output current, the SP1400D suits modern high-current PV modules. Sungrow’s patented snap-fit design enables tool-free installation in around 35 seconds.

For larger commercial rooftops, PLC communication supports loop distances of up to 900m, while module-level IV diagnosis helps installers quickly identify underperforming or faulty modules. Intelligent FHC (Fault Heat Control) bypass technology can also isolate abnormal conditions without disrupting the rest of the string.
