Hello All,
I want to add a contactor on ACinput, ie, when supply fails, the contactor must open so it cannot feedback to grid. When grid returns, the contactor must close again. This is a legal requirement here in SA, and I want to use Quattro and not Multi II
Can I do this on either the relay in the quattro, or the relay in GX device?
How would I program this?
Regards
You don't need a relay of the Quattro or Cerbo for that, just connect the coil of the contactor to the grid and it will engage if the grid is available and disengage if the grid fails.
But in most countries you need a certified Anti-islanding relay for that, not just a simple contactor.

You need anti islanding relays, if it is for some grid standards with the Quattro. It does have an internal relay that opens automatically on grid faliure.
The grid code in Victron Ve config for SA has the programming for the standards to open and close the grid relay. Are they asking for extra equipment? Or the double relay that the Multi 2 has?
Thanks @Matthias Lange - DE and @Alexandra .
Agree with Anti Islanding, but in SA, our electricity provider wants more than just anti-islanding.
PS, This is a 60kVA AC Coupled system so not even sure if the Zehl will work at those amperages.
Regards
