Turn on loads only when there is sufficient solar production

I have an off-grid system consisting of solar panels with peak power of 1 Kwh, Victron Multiplus ii inverter, Victron charge controller and Lifepo4 batteries with Daly BMS.


My desire would be to power a pool pump only when there is overproduction from the PV, so as not to go to discharge the batteries.


is there a possibility to set a secondary or assistant relay, which possibly activates an external 220v relay to turn the pool on and off ? what condition values could I set ?

(the main relay on the Multipluss is already used to disconnect the 12v inverter if the batteries are too low.)


I tried looking at the following product, but of course You need a feed-in of the excess current, because in an off-grid system, the charge controller stops the current from the solar panels or letting only the necessary current through, without making it possible to display the overproduction.

Thank you in advance to everyone who will help me
