SolarEdge vs Enphase: which optimiser system for UK roofs?

Two ways to solve the same problem: per-panel optimisation on shaded or split roofs. The architectures differ at the wire — and so does the price.

In short

SolarEdge fits a central inverter with a small DC optimiser on each panel. Enphase fits a small AC microinverter on each panel and skips the central unit. SolarEdge is typically £500–£900 cheaper on a 4 kWp install; Enphase wins on resilience (no single point of failure) and is the easier system to extend panel-by-panel.
