5-pin Relay with Victron MPPT

Hi,

I am basically trying to have my system cut the load off at night and turn on during the day only. Therefore I have purchased a 5 pin relay to do the inverse of the 'street light' function in the Victron application.

I was hoping I could get some assistance with the wiring as I am a little confused. Please see my pre-schematic below:

Your help would be much appreciated as I've had no luck finding any existing schematics on Google, none of which were interfaced with a solar charge controller.

I am using the MPPT 75/15 and a 120Ah deep cycle AGM battery.

@Samuil try this way -

For load switching you have to use NC pins 30 and 87a - they are connected together by default. In case of MPPT 75/15 activated load output by 'street light' function it will powered relay coil and drop connection between pins 30 and 87a.

Battery voltage and relay coil voltage should be the same.
