My friend and I used different installers and basically installed the same system.
My equipment:
MultiPlus-II 48/5000/70-48 GX; MPPT 250/70 with 9x400Watt Panels; MPPT 150/45 with 3x400Watt Panels (Will be expanded to 6); Energy meter ET112.
The panels needed to be split due to roof space.
His meter is splitting the loads between AC Loads and Critical loads. I.e. when the geyser or oven is switched on, you can see the difference:
My meter is not differentiating between AC Loads and Critical loads. I.e. when I switch my geyser on my critical loads increase:
I asked my installer to change mine accordingly. The feedback I received is that he contacted Victron and according to Victron he did do the setup correct and they do not know how the other installer did it in order to see the difference?? (I am not sure if the same energy meter was installed at my friend)
Any ideas, pointers I can give him?
I also notice a difference in the Grid input into the system. My grid is normally between 40-100W. My friends is normally between 10-30W. What could cause this difference.
