Hey folks, I've recently put in an order for an 8.5kW 2PW system and a site visit is scheduled 2 weeks from now. I've got a detached garage with an old subpanel where I currently charge my Model Y with a pre-existing NEMA 6-20 outlet. I'd like to replace that outlet with a NEMA 14-50 and also potentially have the Powerwalls installed inside the garage if it's possible. I'm pretty sure the outlet and/or PWs will require a subpanel upgrade as it's connected to a 40amp breaker on the main (150amp) panel located 50ft away. Attaching an image of what it looks like.
I received a quote from an electrician and they want $4,500 to dig a trench to run new conduit, install a 100amp panel, and NEMA 14-50 outlet in the garage.
I think that's kind of high and wonder why they couldn't just rip out the existing subpanel, fish in a higher gauge wire from the existing conduit upgrade the breaker on the main panel, and slap on a new panel. Conduit maybe too narrow?
I'm getting a second opinion this Saturday.
Or...are subpanel upgrades already factored into the quote? I'll definitely bring it up during Tesla's site visit I was just wanting to be proactive and not have it be one of the reasons the install is delayed.
Thanks
