SolarEdge S1400 Power Optimizer – Short Input

The SolarEdge S1400 is a power optimiser for SolarEdge string PV systems, with short input cabling for compact module-side installation. It is specified for high-power modules and commercial or large field PV configurations where module-level optimisation, monitoring and safety functions are required.

Key Features

Module-level MPPT

Provides module-level maximum power point tracking for individual PV optimisation.

High-power module support

Rated for up to 1400 W input power, with support for modules up to 700 W and 20 A short-circuit current.

SafeDC voltage reduction

Automatically reduces DC voltage to touch-safe levels when the inverter or grid shuts down.

Sense Connect monitoring

Connector-level monitoring helps identify overheating caused by installation issues or wear.

Short input cable option

Short Input Option uses a short input wire for compact module-side layouts.

Benefits

Supports high-power module designs within the specified electrical limits.
Short input cabling can assist with compact module-side installation layouts.
Module-level monitoring and remote troubleshooting support fault identification and maintenance planning.
SafeDC functionality reduces DC voltage during shutdown conditions.
