Hi, I got two ESS systems with only AC-In connected (no AC-Out connected). However, one system shows me for an unknown reason only (negated) values on AC-Out instead of values on AC-In.
This is how it looks like when I charge the battery from the grid for example:
Configuration is the same on both systems.
ESS grid power setpoint is not working correctly due to that on that system. Any advice on how I could debug this?
Finally managed to fix it myself. For future reference: There is an incidence for AUX current sense ports. It thinks something is plugged in (brand new out of the factory), although nothing is plugged in. Solution: Plug something in and take it out again, done.
In new revisions, the AUX port is no longer used, probably for exactly this reason.
This is what it looks like on the console:
Since it is a bi directional inverter (meaning it can charge from the AC out), am going to ask if you have wired it the correct way around?
As in is the grid definitely connected to the AC IN block?
@Alexandra Thanks for the response. Yes, it is definitely wired correctly, as you mentioned: Grid = AC In (1). No other AC connections.
I think it is totally weird and also did check exactly this twice.
