question

have done some more digging and it would appear that we set the meter setting to 'inverter charger' and then as we have also ticked external current sensor the system should move from external meter to internal meter then external current sensor (meter).

However I would like this 'assumption' confirmed or substantiated by one of the experts that frequent the site if poss ?

Thanks so much.

Ok - It worked as described.

external meter box ticked in VE Config.

Setting for ESS - Grid Metering - 'Inverter / Charger.

This told the multi I wanted to use its own inbuilt meter (current sensor) which was then changed to external meter in use (current sensor) by the VE config setting.

The VRM display shows as if its passing the loads through the inverter, and measuring them with the internal sensor however the reality is its behaving like the parallel AC coupled system it actually is.

A word of caution however - the external current sensor has 2 triangles shown on the outside rim of the sensor, and despite no mention in the manuals these are the 'direction of current flow' markers and need to be in the correct sense ! - Otherwise the multi behaves very strangely.

Yes external needs to be ticked otherwise funny errors spear

Multi and vrm treats it like an external

Victor not recommending but it can be extended I use 3meter high end headphone extension no issues.

Yes I fell for the triangulares as well.

I have mine at all the entry point so the software can see and manage total demand or feed in

Hi,

I've just set up a similar system. I t works but the configuration looks strange.

I have a Multiplus connected to the grid and to pylontech batteries. My PV inverter (SMA) is connected to AC-in. I add a current sensor between the grid and SMA inverter. There is no load on AC-in.

External meter is selected in VE config. In ESS settings, "Grid metering" is set to "Inverter/Charger". To get a correct grid consumption and AC load estimations on the GX, I was forced to declare SMA connected on AC-out in settings even though it is really connected on AC-in. Any comment?
