Solar Edge S500B Power Optimizer (45mm Depth)

Solar Edge S500B Power Optimizer (45mm Depth) is a SolarEdge S500B power optimiser rated 550 W, for one PV module, supplied with a 45 mm deep, original B bracket.

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.

This is the original B bracket at 45 mm depth. The B2 revision is 33 mm deep; SolarEdge document the change in the white paper "S500B Mounting bracket changes (B to B2)". Electrically the two are identical.
