Multiplus II in Balast for cutting-edge renewable energy production

I plan to install two Multipluss on my 3x400N network and I would like some advice. At the moment, I have no production rejection constraint on the grid (Grid), except for power, because my meter limits to 15A per phase. Even though my two inverters are balanced, sometimes I go beyond this intensity per phase. Rather than consuming unnecessarily and risking total triggering, I would like to store that excess energy on a battery, but only when the intensity exceeds 15A or when the discharge power on the grid exceeds 3500W.

Is it possible to program a Multiplus so that it starts charging only beyond a certain level of rejection in the network, depending on the counter on the phase concerned? In addition, I would also like to program the Multiplus to discharge the batteries at a specific time of the evening, until it reaches a given level of charge.

I have the possibility of placing three EM24 meters: one on production, one on consumption, and one on the feeding column that balances the first two. It is on this last meter that I cannot exceed 15A.

Thank you in advance for your help and advice on this issue.

Very cordially,

Hi you can limit grid feed in in the multiplus ess

So pv power will go to grid to a certain amount, and then to battery but you will need scheduled charging for that ( in ess priority goes from loads > battery > grid)

For your second question you can also use scheduled charging

One thing im not sure and have to check is if pv limiting on ac inverters is possible, im sure its possible with mppts however

Also your pv inverters on multiplus ac out should not be bigger then the multiplus can handle 1:0 victron rule
