For anyone still following this thread: - Contrary to the manufacturer's claim I just confirmed that it is in fact 100% possible to measure 240Vac across the contacts of this single-pole relay *when it is switched off*. This is due to voltage sense pass-through at the grid-tied inverter's output terminals. Many thanks to Jarmo for helping me come to this realization - I would like to echo some of the other Wrenches' praise of this message board, such a wonderful resource!
