Peak shaving is not working correctly on one phase

[Pieter101]

I Have 3 phase system and in the settings I have set to peak shave to 20A and keep it there on every phase!

But Phase 1 it’s going up to 32-33 A?!?
The other 2 are staying around the 20 A

Which parameter is causing this!

Hi, did you managed to find the solution on this? I’m experiencing the same issue.. 3phase system using 3x MP II devices.. 2 of them (L1 and L2) are nicely supporting the extra load via AC-IN while the 3rd one (L3) is not. What could cause this?? I can’t figure it out

No unfortunately not. I reduced peak shaving so i got a beter margin so that the L1 fuse does not go…

I just recently reported some 1x MP2 in 3ph grid import limit issues in the new beta thread. Victron will take a look before releasing 3.70. Maybe it would make sense for you guys to try the new beta and report issues in the thread, so Victron can fix this issue also.

Hi, could you please take another look into this? It is an absolutely critical feature to be able to limit import current to protect main fuses. And currently with my MP2 charging at night simultaneously with EV, it will blow the L1 fuse. VM-3P75CT measures main fuse currents, so limiting should technically be possible. Peak shaving as in export from MP2 to protect main fuses is not what I am asking. Just so that MP2 limits its own charging speed if necessary. Thank you.
