Programmable relay not AC out put 2 driven by SOC

Hey

I have 3 stage load shedding i want to set up to load shed based on SOC

I had seen in the manual that there is only the below

6) Programmable relay that can a.o. be set for general alarm, DC under voltage or genset start/stop function AC rating: 230 V / 4 A DC rating: 4 A up to 35 VDC, 1 A up to 60 VDC


I'm trying to achieve the below

Stage 1 Drops out AC circuit at 70% SOC and on at 75% :Relay??

Stage 2 Drops out general power at 50% and on at 55% : Relay??

Stage 3 Essentail drops out at 25% and on at 30% : AC output 2

Thanks in advance

Assumption is that all loads that you want to control by the 3 stages are on AC Output 2?

If so then,

Stage 1 would need to an external contactor that controls the AC circuits you want to drop at 70%, your programmable relay would make use of one of the many relay in the inverter to control the coil of the contactor.

Stage 2 would also need to be the same with another external contactor

Stage 3 would be a straight programmable relay that uses AC output 2 relay to open when 25% reached and then close when 30% is reach.

I realized a similar function with the built-in assistants via VE.Configure Multi software to control the programmable relais of the Victron Quattro
