Hi
Has anyone added or installed anti island on the ac1 out of a multi/Quattro ?
The set up would be multi or Quattro AC coupled on the output 1 of the above inverters
No ac2 out connection
No grid or genny input on the input sides of the multis or Quattro's
The reason for the question is to keep a grid tie inverter on the out put working on grid outage
Regard

Hi, I dont understand your question? There is no need to install an anti-islanding relay on the ac-out.
Hi
Thanks for your reply
In the uk when there is a grid outage no power is allowed to be put in to the grid G99 compliance.
So a for example in a Victron Quattro With no AC grid connected on the ac1 input and the pv is also on the input
But a pv inverter (a fronuis pv inverter for example) connected on the ac1 I put of the Quattro and the ac1 input of the Quattro connected in parallel with the grid And ess assistant installed on the Quattro
In order to keep the pv inverter and the Quattro powering the loads in a grid outage a anti island relay/controls would need to be installed ?
The reason I ask is in most installs it’s not practical and cost affective to swap the installation to essential loads and most would want to carry on using all loads regardless of how big they are. By selecting the appropriate inverter size to suit
Hope this explains
