Perlight PowerPlug MAX 500
Sits right beside the PowerPlug MAX 465 at roughly a £6 premium, for a slightly larger, bifacial panel in place of the 465's smaller, non-bifacial one.

The sensible middle of the register-listed range: enough panel capacity to make real use of the 800W cap, and two independent MPPTs so one shaded panel doesn't drag the other down. Bracket sets included for a garden or flat roof, shed, outbuilding or rear extension roof.
