I was looking at the install instructions for the Home Flex this morning, it only has three terminals for power in? So 6/3 Romex is not needed?
Correct. The Home Flex has terminals for two hots and a ground (no neutral).

If you're hardwiring the Home Flex, then 6/2 is all you need. The Home Flex terminals are too small for four gauge or larger wire.

I'd recommend two six gauge copper THHN hots, an eight gauge copper THHN ground, and running them through EMT. THHN can handle 75 amps, where Romex (i.e. NM-B) can only do 55. That said, if you're good with 55 amps (which is plenty), Romex is more than enough.

Awesome. My main concern is that while I am capable of doing this myself, I am not an electrician. When I pull the trigger on solar this summer, I don’t want issues when “the man” comes from the utility company to inspect.
Go ahead and buy the EVSE. Get quotes from three electricians and just say "here's where I want the charger" and let them make the recommendations on wire, conduit (or not), circuit breaker size, etc. Request a permit and inspection. Everyone's home and panels are different, so it's really what works best for you.

Nice bends! Are you an electrician?

My only concern is mounting the charger on a combustible material (pegboard). Perhaps you could add a metal backing plate?

Thank you. No, I'm not an electrician. Hadn't done any bending before so it took forever but it was good to learn something new. I got quotes from four electricians and hired one because where I live homeowners are unable to pull a permit and get an inspection. The electrician installed a new circuit breaker, connected it to the wire, and got the permit and inspection (we passed).

I installed the Home Flex directly into the cinder block using Tapcons. The unit is encased in thick plastic that separates the circuitry and wiring from whatever's behind it. I could be wrong, but I don't think that plastic would get hot enough to start a fire with the pegboard. The location is directly across from the MME charge port. I thought about removing the pegboard but it is useful for hanging tools. When my MME arrives and I charge it for the first time I will check the temperature of the back of the Home Flex during the entire duration of the charge. If it's warm at all I'll take it down and remove the pegboard. Thanks for the observation.

That's really great bending for a beginner, better than a lot of second year apprentices. If things don't work out, with the labor shortage someone would probably take you as an electrician apprentice if you show them your bending skills. ?

The Flex can get a little bit warm charging at 48A on hot days which won't hurt anything, but the main concern is in case of a failure inside the EVSE like this. The EVSE might get really hot, spark, or start on fire and you don't want that to spread to other materials if you can avoid it. The manual says "Do not install Home Flex near flammable, explosive, or combustible materials." for this reason. I haven't heard of a Flex starting on fire so they seem like pretty safe/reliable units however.

Nice looking installation
I am like you…My MME is arriving in a few weeks, shipped since 2/28/22

I am undecided on what Charger to buy but Chargepoint has good reviews, the other is the Juicebox

I've had that charger for about a year now. My rural electric co-op gave it to me on the condition that I don't charge during peak hours. They also covered half the cost of the installation! That all works great for me. I did have some issues with the programming that either the co-op or ChargePoint did, but we got that straightened out.

Chargepoint also has a plug in version (mine is NEMA 14-50) so if you have the 220V outlet (or have it installed) you definitely don't have to be an electrician to install the EVSE. My electric Co. gave me a rebate for about half the price of the charger plus I get a *small* Amazon gift card every quarter based on how much I charge during non-peak hours (after 11pm). Now all I need is something to charge! ? ?

I personally wouldn't worry about the peg board then installing it into a wood stud like it instructs.

My Home Flex is the NEMA 14-50, I just removed the plug and hardwired it.

Nice! I did almost exactly the same thing, but just went with 6 gauge everywhere. I bought all the equipment, 60 amp breaker, wire and conduit. I did all the work except wiring the breaker and snapping it into the panel. I contacted a local electrician and sent him all the pics and asked for him to look it over, do the final connection for me and give me a signed receipt and initial the panel where the breaker is. He only charged me $75 for 5 minutes of 'work' LoL. I wanted it to be evident an electrician was involved. Here are in progress and final pics. I know, I sux at drywall...

As someone who's used this exact modal for almost a year now, I'm very happy with it.

I also have it hardwired for outside use (no garbage, but dedicated parking space). The reporting is adequate enough for me to separate my budget lines between non-car electric use and car use. Mainly so I can illustrate my car costs $11.64 to "fill up".

I've got the same one, also hardwired. So far so good! Went with the Home Flex because all the public chargers around me are ChargePoint, so I can see the majority of my charging all in one place.

Electrician here. You get an A+ for your pipe bending skills. You went above and beyond with an offset. A simple one bend kick would have worked.
