SolarEdge S1400 Power Optimizer – Short Input
SKU: S1400-1GM4MBWD
SolarEdge S1400 Power Optimizer – Short Input handles 1 400 W / 20 A modules, delivers 99.5 % efficiency, SafeDC™ rapid shutdown and Sense Connect arc prevention, enabling 30 kW strings and fewer BOS components—premium module-level optimisation for commercial solar arrays.
- Manufacturer SolarEdge Technologies
The SolarEdge S1400 Power Optimizer – Short Input is the newest member of SolarEdge’s S-Series, built for commercial rooftops and ground-mount fields that deploy today’s high-current, 700 W+ bifacial or G12 modules. Rated at 1 400 W, the optimizer handles up to 20 A Isc and 125 V Voc, allowing designers to pair two modern modules in series while still benefiting from SolarEdge’s module-level MPPT and SafeDC™ rapid-shutdown technology.
Why choose the SolarEdge S1400 Power Optimizer – Short Input?
Maximum harvest – 99.5 % peak / 98.8 % weighted efficiency plus module-level MPPT extract every possible watt, boosting ROI on shade-affected or mismatch-prone arrays.
High-power module support – works natively with 650–700 W panels at 20 A short-circuit current, eliminating the need to down-bin modules or shorten strings.
Flexible string design – up to 30.4 kW DC per string and strings twice as long as conventional systems reduce cables, fuses and combiner boxes.
Ultra-compact profile – the Short Input variant’s 10 cm input leads minimise excess wiring under the module, ideal for portrait mounting or tight junction boxes.
Future-proof safety – SafeDC™ drops output to 1 V when the inverter is off, while Sense Connect continuously measures connector temperature to stop arcs before they start.

Installer & EPC benefits
Simpler BOS – longer strings (up to 30 optimisers) mean 50 % fewer cables, fuses and combiner boxes, trimming CAPEX.
Rapid deployment – one bolt and MC4s complete installation; automatic string mapping appears in SolarEdge monitoring for instant validation.
Reduced truck rolls – module-level monitoring and remote firmware updates solve most issues online.
Code-ready – IEC 62109, VDE-AR-E 2100-712 fire safety and FCC Class B EMC compliance streamline approval in every major market.
Ideal applications
700 W bifacial trackers seeking longer home-run strings
Commercial rooftops where partial shade or layout complexity threatens yield
Retrofits upgrading to high-current N-type modules without restringing
Upgrade your next project with the SolarEdge S1400 Power Optimizer – Short Input and deliver higher energy production, lower balance-of-system costs and industry-leading safety in one compact device.
