In Australia, the government has much more control over what connects to the grid. I'm really struggling to find someone who will install a Victron inverter (Multiplus II) because making it compliant seems complicated if not impossible with anything other than an approved battery. I'm not 100% sure, but from what I can tell even the batteries need to be CEC approved for connection, meaning any CEC approved installer won't touch the install of the multi plus II because it cant comply with anything other than a shortlist of paired batteries.
I already have on my main house a 3 phase Enphase micro inverter system - Its 33 panels split to 11 on each of my three phases. So 2750w per phase.
The Victron I had planned on installing in a shed (on one phase) and linking to my batteries.
