Zero grid feedback settings from micro’s avoid battery loading

Is there a way (setting) to trigger my micros or multiplus 2 via Cerbo or multiplus settings to charge my Pylontech batteries?

With normal grid profile everything works as expected. With zero grid feedback settings in the micros, and with a battery of e.g. 50 % soc, the multiplus does not charge the batteries.

Any suggestion is welcome

Helps to know what micros you are using?

Enphase iQ8

Since theres not much info about your system, we have to guess. The Enphase system is using their IQ Gateway, which measures the grid current through a current transformer? Same for your Victron system, its setup as an ESS measuring the grid current with its own CT? Theres no load or PV on the ACout on the MP2?

Leave the Enphase system on feeding excess back to grid and let the Victron ESS on zero feed-in. Then the Victron will take whatever power is fed back from the Enphase

Thanks for the reply.

Can your Victron System see the solar production from the micro? If not that’s your first port of call get it we’re it goes to the MCB or RCBO and put either the VM3P75CT or simular and just say what side that solar production is coming from as at the source/MCB RCBO it’s just a fancy grid tie system. Ie that’s if your Victron doesn’t know there is solar there already.
