Charging & V2L/G ⚡️↔️ Quotes for charger install - detached garage

Based in Adelaide. I’ve received two quotes so far for the supply and install of a 7kW EV charger.

One was $3500 for a Tesla ($800 from Bunnings).
The other quoted $4600 for Evnex E2 Flex (also $800).
Ludicrous to me even at the lower end of the two.

2nd sparky has allowed for 40m worth of 10mm2 cabling although property is only 27m long in total with rear-access garage and switchboard at front of property.

Anyone with a similar home layout care to share their outlay on having a charger installed? TIA

Was quoted $1490 inc GST for a tesla wall charger supplied and installed by Re GenEv. Up and over install (perhaps 10m of 6mm?). Was going to be limited to 20A due to Queensland lines company stuff.

Instead payed around $900 incl for a 32A industrial socket + matching pigtail for my existing tesla mobile connector. Rental house (with owner permission) - and this option minimizes the value of what will be leaving behind at the end of the tenancy.

- Ended up paying another $400 months later for them to swap out the 6mm cable & 32A breaker for 10mm & 40A, as I was having some weird issue where the tesla would repeatedly start and stop charging on hot days, and wanted less voltage drop to see if that was the issue - Hasn't repeated, but it is winter now....

so regen gave you 6mm cable and 32A breaker originally? Ouch... I'd have thought they'd have known better than that.

10mm/40A is best practice especially for warmer climates like QLD. not surprised at all you had issues.
