S1200 Power Optimizer (Short Input 0.1m)

S1200 Power Optimizer (Short Input 0.1m) is a SolarEdge S1200 power optimiser rated 1,260 W, for up to two high power or bifacial modules in series, supplied with a 0.1 m short input lead.

A power optimiser is a DC-DC converter that sits behind an individual PV module, between the module and the string. It tracks that one module's maximum power point continuously, so a module that is shaded, soiled, differently oriented or simply weaker than its neighbours no longer drags the whole string down to its own output. The optimiser then presents a fixed, well-behaved voltage to the string, which is what allows longer strings and mixed orientations on the same inverter.

The S-series commercial optimisers take two modules in series through a single input, which halves the number of optimisers, brackets and connections on a large roof or field array. Fewer cables, fewer fuses and fewer combiner boxes for the same installed capacity.

It also reports each module's performance back to the monitoring platform, so a fault is traced to a single module rather than to a string, and it drops the module's DC voltage to a touch-safe level automatically whenever the inverter or the grid shuts down — SolarEdge call this SafeDC.

Includes SolarEdge Sense Connect, which continuously monitors for connector overheating caused by installation faults or wear.

Before you order

• The S1200 has a higher operating current than the optimisers it replaces. When pairing it with an inverter that has built-in 25 A fuses, those fuses must be replaced with 30 A fuses before commissioning. The fuse replacement kit is part number FLD-DCD-SEL1-FUSE. The affected inverter part numbers are SExxK-xxxxIxxCx, SExxK-xxxxIxxDx, SExxK-TWxxIxxLx and SExxK-xxxxIxxZx.
• The S1200 cannot be mixed with any other power optimiser in the same string.
