Hello everyone,
I come here because I have just installed an MultiPlus II for doinf ees.
My installation is :
MultiPlus II GX + 1 ET112 for metering PV production (USB connected to the MPII + an external current sensor connected to the Current-sensor input of the MPII (measuring the current of the main input grid phase)
System :ESS
Grid connexion : 6kVa
PV installation : 6kW connected on the only ac-input of my MPII
Loads:
- two electrical vehicule plugs connected directly to grid line (before the MPII)
- all remaining loads on the AC-ouput-1 of the MPII
Battery : 7.2 kWh Pylontech US2000C batteries
Sensing : two current sensors wired on an Shelly Pro EM energy meter (one measuring the current of the main input grid phase and one measuring the AC-ouput-1 of the MPII
Fisrt of all, everything seems to work properly, grid feed if solar production to small for the loads. If small load and PV production → Battery charging. If no solar production and battery above SoC → bateery ffeds the loads.
But The reporting on the VRM portal or the local interface is strange :
- my PV inverter is shown on the load side (whereas I have configured the Et112 as an PV inverter meter on the ac-input-1)
- the consuption of the grid is totally stange. Indeed, the main wattage indication is completely diffrent from the one that my shelly reports and from the actual load consumption. But the load reported for the L1 line is correct (for example, wattage grid -2414W and L1 wattage -177W. Notice that -177W corresponds almost to the active power reported by my shelly pro and -2414W corresponds almost
to the Apparent power reported by my shelly pro.
Bonus question : why on the energy meter configuration panel for the position there is AC-input-1, AC-input-2 and AC-output whereas actually my MPII have one AC-input and two AC-ouput. It seems inverted.
Please help. Thanks.
Thomas
