Hi There, I have this installation - With random WARNING - L1 OVERLOAD
1x Multiplus II 48/8000
1x MPPT 150/85
1x Solis Grid Tie Inverter 4.6KW (Grid Side)
2x BSL 5KWH PowerlIne
With The ET112 grid meter I get the "AC LOADS" reading in VRM that accurately shows the extrenal heavier loads. These are Pumps for water, Irrigation, Stables. This is very usefull, but I keep getting random "WARNING L1 OVERLOAD" messages. It never goes to an actual alarm though. I belive it might be inrush currents on the "AC LOADS" side. eg. borehole pump running or starting a lawn mower. Below an image of heavy load test on the AC1 output (no errors), this only seems to happen (VERY RANDOMLY) when heavy loads run on the grid side (HEAVY EXTERNAL LOADS). Why is this? These loads are supposed to merely be suplemented by the system and not supplied.
The screen shot on the left was taken during such a "Overload L1: Warning VE.Bus System [276]" event.
The screen shot on the right was taken during a test with NO overload warnings at all.
Does someone know what it is that is going on here?
