hoi,
could i use a victron transfer switch to switch the PV inverter between grid and the quattro ac-output?
i think it should work, the only thing i see "wrong" is the freq (50hz). if it switches to fast.
to solve this i think i need a 10sec delay on the input 2 also?
why and how i wanne use it :
how:
switchbox input 2= grid
switchbox input 1= inverter output (my load) and the K11 ( output will the triggered via a 12v relais in front of that = via pulse from quattro relais)
switchbox output = pv inverter
working with the relais function in the quattro= PV use till 90% battery soc than switch to the grid
and switch back from grid to battery at 75% battery soc.
so if i see this right, "shore" (input 2) is always on , except when the pulse-relais is active (input 1. after 10sec.)
why:
because the PV on quattro output , keeps on losing power (switches off whenand battery is almost full) and because the freq. shifting is not working very good , ABB inverter)
and PV on the quattro input , does not use that power to load battery
