Dear community,
This is my setup:
Basically, the standard setup with solar on DC, AC-OUT and AC-IN.
This is the overview screen at night time (inverting from battery):
VRM is the same. I wonder where the AC Loads number comes from - as you can see, I do not have any non-critical AC loads, only AC-IN solar, but it is currently 0W (night time).
Is this the Multiplus' own usage? Does not seem like it - it is not stable, but oscillates just like the grid load. It is mostly zero, but every 20 seconds or so jumps around wildly.
Something is not right. A measuring error?
Please note that the screen looked more or less right, as long as the ESS meter was set to "Internal". That is, without using a grid meter, only the PV solar meter:
The layout is also much cleaner. I found out that AC-IN and AC-OUT inverters are summed up under PV inverter and was able to separate the two values using a simple mod of the interface files (hence the +)
But this configuration does not use the grid meter... it was slow to regulate the grid feed to when doing zero-feed-in, so I thought I need to add a grid meter, as recommended. But maybe that was a mistake.
System is one phase.
Any ideas?
Thank you!
