Description
The SolarEdge S1400 Power Optimizer represents the next generation in smart energy performance, enabling you to push more power per string while lowering system costs and increasing layout flexibility. With support for 700W bifacial, G12, and rectangular cell panels (182–210mm), it’s the go-to solution for modern commercial arrays with cutting-edge modules.
Why Choose the S1400?
- More power per string: Connect up to 30.4kW in a single string, reducing BoS components and cabling.
- Next-gen panel compatibility: Works with high-output 700W bifacial panels and large-format G12 modules.
- Optimised for flexibility: Place modules at different tilts, angles, and orientations — all within the same string.
- Compact & easy to install: Thinner profile and simplified cabling for tight spaces and faster installation.
- Real-time safety monitoring: Sense Connect detects overheating or bad connections at the connector level.
Designed for Commercial Applications
The S1400 is ideal for complex commercial and industrial sites including:
- Flat-roof arrays with panel layout limitations
- Carports where longer strings reduce trenching costs
- Ground-mount fields with high-wattage modules
With each optimizer supporting two panels, the S1400 allows installers to reduce labor and materials while maintaining full module-level performance tracking via the SolarEdge Monitoring Platform.
Safety, Smarter Than Ever
Integrated SafeDC™ technology ensures that during grid or inverter shutdowns, module voltage drops to 1V — keeping installers, first responders, and property safe. Combined with SolarEdge Sense Connect, the system detects and prevents potential arc faults before they can occur.
Who is it for?
The S1400 Power Optimizer is perfect for:
- EPCs and installers working on commercial rooftops, ground mounts, or carport systems
- O&M professionals needing pinpoint visibility and low-cost, long-life infrastructure
- Designers looking to integrate high-output or bifacial panels in challenging layouts
