I am baffled! Perhaps a technical expert on the forum or from Victron can explain the following apparently bizarre behaviour:
I am using an assistant to set the general flag to Ignore AC Input 1 (which is connected to the Grid). When the flag changes state I hear what sounds like a relay operate inside the Multiplus 2. From the diagrams in the manual, front cover and another answer on this forum I assume that an internal relay is physically disconnecting the Multiplus from the Grid. And yet, my smart meter readings show that I am using grid energy when the Multiplus is apparently disconnected from the Grid!!! (Approx 1Wh every hour or so - yes a tiny amount but not ZERO). This has been going on for over a month.
Ah, thought I - the smart meter is recording its own self consumption, its about the right order of magnitude. EXCEPT, in the days when I disconnected the Multiplus from the Grid manually, the smart meter was recording ZERO energy use as expected during those intervals.
How can the Multi be consuming energy from the Grid when disconnected from the Grid?
