EV link charger only charges Tesla at 20A
Hey,
I started this trial with a Nissan Leaf, which I still drive, and had a single phase EV Link charger installed. This charges my leaf at 30A no problem. When I plug a Tesla in, it only charges at 20A.
Anyone have any idea why?
Is the Tesla detecting a faulty installation?
It makes me a little concerned as apparently Tesla is better at only charging at what the charger is capable of providing.

Yes in Brisbane if you are on a single rate tariff EVSEs are limited to 20A.
im in the same boat. At first I was annoyed. But I’ve come to accept it and frankly 20A is heaps for my Tesla which I generally limit to 16A and only charge off solar

Good question. Not something I've looked into. But knowing the intent of the regulation is to limit demand on the grid during peak periods. I would say the 20A is limited to the property. ie if you want a 2nd EVSE you would have to run each of them at 10A or have 2x EVSEs that support smart load sharing of a 20A circuit. But again I'm not 100% sure on this and it may well not be a problem considering it will be a minority who install more than one EVSE.
This is the energex info pertaining to it https://www.energex.com.au/home/control-your-energy/smarter-energy/electric-vehicles/charging-your-ev
FYI though. If I were you and were going to install 2x EVSE. I would consider 3 phase.

Good question @Spinbot, and thanks @Macca_779 for jumping in and answering!
One of our learnings from the trial is that almost half of the chargers that were installed have had their charge rate limited, and we have a piece about this in our third lessons learnt report (see Section 3.3.1 on pages 8 & 9) that elaborates on the reasons that this occurs.
At a high level though, in addition to the Energex network restrictions that you called out @Macca_779, many others had to be limited due to household wiring, switchboard or service fuse constraints.
Whilst we expected this to happen, the frequency of it really surprised us!
A side note to @Macca_779 - I saw you mention that you limit your charging to 16A, and only charge off solar - how do you go about achieving this? Helping customers maximise their solar self consumption is something we're really interested in, so I'd love to know how you do it!
