I have a 2018 Model X. I am in the process of upgrading my house to add a back-up generator. I live in the hot state of Texas and am looking to get a 20KW unit so I can run both of my power hungry AC units in the middle of Texas summer.
On the worst days in July/August I am pulling about 9KW for the AC units. On those days the AC units run pretty constant until about midnight or so.
I currently have a Tesla Wall Charger with 90 Amp breaker (200 Amp house service)
I currently have it set for charging at 72 Amp, but given our somewhat limited (50 miles) daily around town drive, can certainly reduce the charge rate to fit within the back-up generator constraints. I have it start charging at about 2 AM, and we seldom use the car before 8 AM. In short - I have over capacity, under utilization of the curent charging capability.
In my discussions with one potential generator sales / installer, he mentioned there might be an issue with EV charging on a stand-by generator and that I should look into that. I believe the issue may be in the harmonic distortion / frequency stability performance requirement.
Does anybody have any information of charging via a stand--by whole house generator, or know the power input performance requirement for the Model X on-board charger??
