I have a site that uses a VM-3P75CT Energy Meter but the reading is not stable (see film). Is this normal behavior? I can imagine that this kind a measurement makes it hard for the multiplus to regulate the grid current.
The solar micro inverters are from enphase and measured with a victron ac current sensor.
Looks normal to me, i have an em540 that does that too, bit slower but looks similar
Okay.
It also messes up vrm readings.
How are the readings of the phases?
It’s just 1 phase in this situation.
After the charging has finished the reading is stable. Looks like the multiplus 2 and the VM-3P75CT are in some kind of resonance loop.
