I'm currently building my energy storage (on grid) consisting of a Multi Plus II, generic battery and PV inverter from SolarEdge (SE7K) with the SE modus energy meter (SE-WND-3Y400-MB-K2).
At this stage ONLY the Venus GX is connected, the Multiplus II is still in its box ;-)
As written in the FAQ the Venus-GX was able to find the SE7K.
Now I'm able to see the production of the SE7K.
My problem is that concerning the total AC-consumption it equals the SE7K production. This is not true. During the night it shows 0W for the AC loads but the SolarEdge portal shows me that that there is consumption from the grid.
Day (with PV production)
Night (no PV production)
Does this mean I need to buy an additional energy meter (e.g. EM24) if i want to monitor the total AC power consumption that I'll be later able to feed only so much energy from the battery that my purchased energy will be zero?
As far as I can see from the SE portal the power taken from the grid is also available from the SE Modbus energy meter.
Help greatly apprechiated!
