SolarEdge S1200 Power Optimiser – 1200W High-Power Support

SolarEdge S1200 Power Optimiser: The High-Capacity Smart Optimiser for Large Commercial Arrays

Engineered to meet the demands of high-output solar arrays, the SolarEdge S1200 Power Optimiser enables module-level performance, enhanced safety, and design freedom. With support for two large PV modules and advanced monitoring, it offers a scalable solution for larger commercial rooftops and field systems.

Optimised Output for Bigger Modules

The S1200 supports up to 1200W of rated input power, making it ideal for pairing with the latest generation of high-wattage or bifacial solar panels. Its module-level MPPT ensures peak performance from every panel, even in shaded or uneven arrays, helping to reduce mismatch losses and boost system revenue.

• 1200W rated input for higher capacity PV modules
• 99.5% peak efficiency and 98.8% weighted efficiency
• Minimises shading and orientation losses

Advanced Safety Built-In

The S1200 is equipped with SolarEdge’s industry-leading SafeDC™ technology, which automatically reduces DC voltage to a touch-safe level during shutdowns or inverter disconnection. It also includes Sense Connect, a smart thermal sensor that detects abnormal connector heating, ideal for preventing faults and fire risks in demanding commercial setups.

Efficient System Design and Fewer Components

Supporting up to two modules in series and high string currents, the S1200 allows longer strings, less wiring, and up to 50% fewer balance of system components such as fuses and combiner boxes. This flexibility makes installation faster and significantly reduces labour and material costs.

• Connects to 2 PV modules with simple cable management
• Enables longer strings and higher system voltages
• Reduces installation time and BoS expenses

Pinpoint Monitoring and Streamlined Maintenance

The S1200 enables real-time module-level performance tracking via the SolarEdge monitoring platform. With detailed fault detection and remote diagnostics, commercial system owners and O&M teams can resolve issues quickly, cutting down site visits and improving system uptime.

FAQs

Can the S1200 be installed alongside other optimiser types?
No – only S1200 optimisers may be used within a single string for correct operation.

What is the maximum module current supported?
The S1200 supports up to 15A short-circuit current per module and up to 20A output current.

Does it support remote performance monitoring?
Yes – all module-level data is visible via the SolarEdge monitoring platform, helping streamline maintenance and boost performance insights.
