Man Qmerit quote to install Powershare is insane

[mongo]

I had a local neighborhood licensed electrician install my 2nd Gen 2 HPWC in my small garage for the CT, while I was still waiting on my Powershare Gateway to ship. It's a 75' run since my panels are in the main 2-car garage and the 1-car garage is on the other side of the house. To save on install, I had him run ~75' of #3 Al NM-B wire to a 60A disconnect right next to the HPWC and then ~4' of #4 Cu MC for the final leg since neither the Gen 2 HPWC nor the UWC is rated for Al conductors. My other Gen 2 HPWC is #6 THHN (#10 THHN ground) in 1" EMT that I installed myself. The installer that Qmerit connected me with said either was sufficient for the UWC install.

They are, I was trying to figure out how much "rework" was needed.

My install is full panel (one 200A out of the two I have) with Gateway outside, 50 feet underground (existing PVC) 100A run to new subpanel in detached garage, then EMT conduit overhead to the third bay. ~$6.5k.

yours seems reasonable, I feel like my quote is $4,000 too high

I paid $2600 for install of gateway and charger. No reason to be hostage to this particular company. I usually use Yelp to get multiple bids for jobs or I suggest you reach out to Tesla for alternative qualified company. They have an email for problems, I'll send in follow-up message

Mind you I already have 2 Tesla Universal Wall Connectors installed by a certified electrician and QMerit wants $10,885.88 to Install the Gateway which cost me a separate $2500.

Basically without Qmerit whom works with a local electrician we have no other choice correct?

Also is any of this eligible for the 30% Fed Tax Credit?

Sorry for so many questions this sticker shock is unreal!

For $10,000 I would get a natural gas back-up generator (assuming you have natural gas at your house) I did three years ago 24,000 kw and it is good for the whole house. I would probably not charge the CT while both a/c were on and both of the double ovens were in use (which is not likely to ever occur)

The problem here in SFlorida is that we are in the tropics and any system exposed to the elements takes its toll. I had one and after 5 years the electronic boards had to be changed….good,luck trying to find one. Also have a natural gas under ground tank. It also supports my pool heater; it is starting to leak along the lines. Everything is relative,and depends how long he plans to keep the CT. I believe he can get a Tesla certified electrician for about 3k less in this region.

Are you sure that the quote was not done by Ben Dover?

Do you have 2 HPWCs setup to load share? I assume that EMT is continuing on to something else further down the circuit? As long as that is #6 THHN in that conduit, that's sufficient for Powershare. You might need to run it separately from a 2nd HPWC (if that's what it is), since I don't know if load sharing on the UWC and Powershare are compatible.

Looks like your setup is otherwise similar to mine, 320A service split into 2 200A panels? Did you choose the Heavy Loads Backup install option or did they? Your panels look to be a mix of both high and low loads, buy my install is mostly low loads in 1 panel and high loads in the 2nd, so I had them go with the Main Breaker Separation install, which makes my 1st 200A panel a sub to the gateway. Since my 2nd panel had mostly the loads I didn't want backed up (minus the fridge circuit I had moved) it was a no-brainer. If you have a mix of loads from both panels you want backed up, the heavy loads backup might make sense, but I have no idea why it is so much more expensive than the main breaker separation install.

Load sharing is compatible. While load sharing two HPWCs is a Tesla feature, they actually do NOT recommend installing it that way if you’ve got enough capacity in your breaker box to run them separately. I was going to do it with my recent PowerShare/Gateway/Powerwall/dual charger/solar install, but the electrician talked me out of it after pointing out the compromises inherent in splitting down the available amps when using one breaker to charge two vehicles. Tesla also suggests that running them separately is a superior approach. Nice tech, but better to keep it simple.

To be clear, Group Power Management isn't limited to feeding from a single breaker. For example, if a main panel only has 70A of continuous capacity available, one can install two (or more) WC, each on an individual 60A breaker, with the combined power limited to 70A continuous. Any WC can then output 48A on its own. Without GPM, the sum of the limits of the WC would need to be 70A, so 48-16, 32-32, etc. A three EV household with three bay garage could really benefit from GPM.

Of course, if total available is only 48A continuous (or less), feeding multiple WCs from a single breaker doesn't impose additional restrictions.

Group power management precludes using Dynamic Power Management, which is more useful to me. GPM requires setting up primary and follower chargers, and can be used for up to six chargers. I agree that it is most useful for locations with more than two chargers, unusual for residential situation.

Group Power Management Overview
The firmware-based group power management feature enables up to 6 Wall Connectors installed at the same site to intelligently share the site's total available power via unit-to-unit Wi-Fi. This minimizes the need for many residential and commercial applications to have specific electrical upgrades for concurrent multi-vehicle charging.
During the commissioning process,

• Wall Connectors are allocated to individual branch circuits (each up to 60 amps)
• Total power is allocated to the group of linked Wall Connectors

Dynamic Power Management
Dynamic Power Management adjusts charge rate in real-time based on the available power in your electrical panel. This means your charge rate will always be the fastest possible, while ensuring that total power being drawn from your panel is within safe limits.
