L1/L2 Multi+ measurement readings on a 230v Split Phase with Autotransformer

Hi,

I have setup a 48/5K/70 Multiplus for a Home Split-Phase configuration, using the Autotransformer Diagram below where L1 is connected to the L1 on the Multi and L2 is connected to the N on the Multi and then using an Autotransformer to step down from 230v to 115v/115v



My question is: Is this taking the measurement that shows in CCGX and VRM from L1+L2 phases? is the value showing there is a total from L1 and L2, or it is only showing L1 (phase1)?


VRM shows data only for Phase 1 and not for phase 2

Those measurements are being taken for current flowing out of the MultiPlus its self. It is the sum of L1 + L2. There are no current measurement sensors in the Autotransformer to allow separate L1 or L2 current.

Hi WKirby,

Thanks for your answer. It is understandable that the readings are made by the multiplus and not on the transformer.

Since I am feeding the ACin from the grid with 2phases I was expecting to see phase 1 and phase 2 in separate reading. But looks like there is no way to configure 1 Multi to read and show the reading by phases.
