SolarEdge S650A Power Optimizer (Isc 15A) short strings and multiple orientations.

SolarEdge S650A Power Optimizer (Isc 15A) short strings and multiple orientations. is a SolarEdge S650A power optimiser rated 650 W, for one PV module.

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 is SolarEdge's residential range. One optimiser to one module, a single bolt to fix it, and MC4 leads already fitted at both ends.

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.

String design

Before you order

• The S650A is compatible only with the SolarEdge Home Wave Inverter — Three Phase (SExxK-RW0TEBxN4) from firmware 4.23.XX and above, for inverters produced after WW42/2020, and the SolarEdge Home Hub Inverter — Three Phase (SExxK-RWB48BFN4) from firmware 4.23.XX and above. The production date is in the inverter's serial number on its label (S/N: SJWWYY-xxxxxxxxx-xx).
• S650A power optimisers must not be mixed with any other power optimiser on the same inverter.

Additional suggested items

Ordered with this optimiser more often than anything else:

• SolarEdge 10,000W Home Wave Inverter - Three Phase
• SolarEdge 9000W Home Wave Inverter - Three Phase
• SolarEdge 8000W Home Wave Inverter - Three Phase
