My setup in a nut. 3x Qudrro 15kva in 3 phase, solar array and battery bank plus colour controle.
All works well what I would like to do is the following. When my system reaches its lowest SOC I would like the inverters to revert back to grid supply and when SOC maximum is reached again I want the grid supply to be switched of again. I hope I made my self clear any help or advice would be helpful. Thanks
Hi Mecodel
This is how I do that.on my unit. (see below)
I then use the generator autostart function on my venus to turn the Gen Flag off and on (as you have 3 to control, you would need to parallel all 3 Quattros Aux 2 relays controls to the one Venus relay, so that all were closed or all are open) This works on my stand alone unit so be aware. I dont know if there are issues joining all 3 Aux 2 togeather
OR you could try the below but the SOC here is the SOC in the quattros battery monitor
use more assistants to turn the General flag on and off based on the SOC.
these would also have to be on all 3 quattros but then no aux are used but its harder to change and trigger manually.
Hope this helps
