I dont know if this is related to VenusOS update 3.62 or if it was so before 3.62 update, but how come AC Load is wrong? It only shows load on L2 (L1 and L3 is not 0 in reality). Also total consumption is higher than the input power (from battery).
If I reboot Cerbo GX it shows correct values for a few seconds then it changes to the picture above.
Is it a bug or why does it behave like this??
The correct AC Load should be battery discharge minus grid export minus critical loads, in this example:
1661-58-1196 = 407W split across L1,L2,L3 and not 1023W on just L2…
I have also tried to reset the VEBus and power cycled everything, but no change.
calculated your values with different phase order
L1 -124 103 326
L2 -476 60 17
L3 548 248 853
-52 +411 +1196 = 1555 (+loss=1666)
if my AC load values (103/60/248) are realistic this could mean that phase order is not, is ist possible to change the phase order for your meter in VenusOS? in my system its fixed
I remember when I installed the system that Cerbo GX or VRM (dont remember which) gave a warning “Wrong phase order”. So I reconnected/switched 2 of the multis, and the warning disappeard
Strange that I never noticed this before. Thanks for your help, I will check the connections and report back.
Problem is now fixed. In the sub central where the MPII’s are connected the phase sequence was wrong, so it did not match the grid meter. And since I got a “Phase Rotation” alarm when I installed the MPII’s I switched the input of 2 of them, so they where happy anyway.
Now I corrected the phase sequence in the sub central and setup the MPII’s with the correct phase sequence and everything is good.
