Hi Matthijs, thank you for your reply. I don’t really need a feature that would protect my main fuses when something else than Victron stuff is consuming too much. The MP2 doesn’t have to export to peak shave. However, currently my MP2 can and will burn a main fuse when my 3ph EV is charging at night, if DESS decides to charge as well. I need to have something to prevent that. What would be the preferred method?

I already have an expensive VM-3P75CT monitoring the entire house consumption, so I think using it + some Victron control/setting is the way to go. If grid import limits are really not available or even planned, are there other ways to accomplish this?

I suppose one half ugly patch solution would be to use some Victron MQTT channel to limit MP2 consumption when EV charger is running. This could be done by Home Assistant. Which channel would you recommend, perhaps DVCC charge current limit or even the grid current limit? Thank you.

I doubt I am the only one with 3ph EV charger and an MP2 based battery system, so surely someone else has ran/will run into this issue as well?

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.
