Ideal or Cost Effective Home Charging

It does change. The lowest current is still 5A so the lowest charge rate will be 3.6kW.
Just to add to that...
If you want to charge from excess solar, you will be better off with single phase up to 32A. That means it can charge between 1.2kW and 7.6kW at 240W increments.
With 16A 3 Phase you can charge between 3.6kW and 11kW at 720W increments.
I think to be realistic using a Zappy or similar single-phase and using excess solar only to charge your car you need at a 10kw inverter and 13kw or more solar panels. Even then on a good day, you will only get the max10kw two or 3 hours during the middle of the day.
It depends how often and how far you drive.
Even at 1.2kW you can charge a Model 3 at 7km/h. That may be more than enough.
With a 5kW inverter you may get 4kW or more of excess solar so that would be 20-25km/hr.
You are spot on in my case, I have 6.6kw but east/west facing hence the 5kw inverter. I wanted larger but at the time the next step up was 10kw which wasn’t worth it.
I have space for another 5kw north facing.
My work commute it 170km round trip so can’t recoup that daily. I just want to scavenge as much as I can rather than getting my 0.06c fit to then purchase it back at 0.18c
Hi All, hopefully this is easy for someone to answer that has this particular 5 pin 32a adaptor. It says in the specs that it automatically sets the charge to 32amps which I hope isn't actually correct. I will eventually have installed a 5 pin config single phase only so I don't want it to run at 32amp when plugged in at home.
1. Is that spec wrong or is it easily configurable via the car?
2. Will it work with lower than 32 amps?

You set the amps from either the car screen or the app in 1 amp incrememts (as well as amount of charge you want). It recognises location so will always be at the set amperage when at home. I think 7 amps is the lowest? Havnt used single phase in a while so someone else might be able to clarify the minimum amps that can be set.Hi All, hopefully this is easy for someone to answer that has this particular 5 pin 32a adaptor.

The minimum is 5 amps. Although I have 3-phase, so it’s 5A per phase for me.
I thought single phase 32a socket was 3 pin? Can you install a 5 pin one and have the other 2 just blank?
Yes, my house currently has single ph with the 3ph plug shown. The plug is wired all the way back to the meter box with 3ph wiring, but 2 phases are just left disconnected from the mains as there is nothing for them to attach to. This was done this way about a year ago, I’m going through the 3ph install now and they will be wired in later.
I’ve read some sparkys won’t wire a 5pin plug up to 1ph home. The guy who wired the plug was the Tesla recommended installer and the 3ph installer is a different sparky altogether, neither had a problem with how this was done.

In effect the adapter tells your car it can ask for up to 32A. Similarly the OEM tails limit current to 10A or 15A
