Yes I installed the Anti-islanding system and the 15kVA Quattro is also now on the LCT register and the Export Limiting register. To be fully NC7 compliant you do need the anti-islanding unit as well, as ESBN want redundancy as part of the regs.
I posted my system on here a few weeks ago and I am up and running. Working great…the 15kVA Quattro is a charging and inverting beast..tested the backup and the lights didn’t even flicker.
