I am looking at wanting to upgrade my household switchboard to a 3-phase power supply from a single phase. Reason: fast charging of EV at home (in the future).
• Location: Melbourne
• Grid: United Energy (UE)
• Meter Type: Smart Meter
I have initially reached out to United Energy Connections department for their advice regarding suitability for the conversion to 3PH.
They have responded with a very confusing email asking
Kindly ensure that before you request for the job, the 3PH supply should be available in your area.
That was essentially what I was trying to find out before I would engage a REC via hipages.
My question is: for those of you who have gone through the process of upgrading to a 3PH power system, could you please share your experience regarding how you went about getting the job done?
Were there any hurdles that you faced, and any gotchas to be aware of?
Approximate cost of upgrade (ballpark figure)?
Also to be noted, the solar system that I am planning to install will be using high efficiency LG panels with Enphase micro inverters, which I believe will only export power on a single phase, i.e. there will be no 3PH string inverter involved. Furthermore, from what I have read on SolarQuotes, current battery tech can't achieve "Apocalypse Proof Battery Backup" with a 3PH string inverter.
