Unable to set Peak Shave Current Limits

Hi there,

I’m attempting to set current limits under the Peak Shaving menu, though both options are disabled (and can’t be enabled). What would cause this?

This is a system consisting for 4x 10k Quattros in a 2x2 split phase configuration, with a 200A 120v/240v grid connection.

All loads are on the AC Out 1, and the grid is connected to AC In 1 (with Venus configured accordingly).

Thanks!

Do you have an energy meter?

No, we have ESS set to use the internal meters of the Quattros (given all loads are on the load side of the system).


Hmm, so thinking about this a bit more: do the Peak Shaving current limit settings in the screen above only apply if there is a grid meter?

Said differently, if there are only loads on the ‘AC output’ side of the system — so no grid meter needed — then the AC Input Current Limits become the limiting factor for Peak Shaving.

I am running the following:

MultiPlus2 - 3kVA fw 2629552
ESS Assistant ver. 018C (Optimized without batt life. Min. SOC 60%)
Vernus OS 3.63
Carlo Gavazzi EM112

The IMPORT Peak Shaving button remains grey and not clickable
