Your land lord might be willing.... what about apartment complexes? I'm sure there'll be lots of cool landlords, but maybe just as many unwilling to allow a tennant to tear into their walls. Land lord may require you to use a licensed eletrician and depending on the location of the breaker panel, it could require drywall work and a long run of wire thru the attic. Just depends. Could also be that a renter doesn't want to pay for improvements to the house he doesn't own and he'll just take the meterbase adapter with him when he moves.
I am concerned about someone yanking the cable and will recommend that it be attached to the house with a strain relief. Also, the box can be remoted from the meterbase with seal tite and the j1772 box can be hard mounted to the wall of the structure.
Thanks for your observations!
I think you may be going down the wrong road. You have a clever solution that is minimally invasive to a property and works very well when a meter panel is convenient to the parking area. That should be interesting to landlords, who really don't know a lot about EVSE, and professional electricians.
When you begin to talk about 'tear into walls', run lines in the attic, and 'hard-mount' things to a building, that's not your product is it?
Also, when you imply this can be installed without 'a licensed electrician', almost by the renter surreptitiously, you may find some city inspectors and local codes have a different opinion. Even cool landlords will be perturbed if they visit their rental and find this attached without their permission.
It's good that you are pursuing a patent, it can be used to pay legal judgments due to perhaps irresponsible marketing.
However, if you view landlord reluctance as a lack of education or understanding, you may have a good product.
I do not own multiplexes, yet all of my properties have some extra feature I had to put in to gain a good tenant or differentiate the property in the market. All of the additions made me wince until I found the cost and discussed with the tenant. (Do you know how much it costs to put in a natural gas barbecue? How about replacing a washer-dryer? That's sunk cost. I would much rather put in 14-50R sockets...) I have had generator taps and EVSE sockets installed for tenants in exchange for an extended lease or a few extra dollars a month.
What I want to do is avoid losing out in the market or losing a good, long-term tenant. Simple solutions like yours make it possible to talk about options.
But if you start by pitching this as a 'do it yourself, don't tell the landlord', it won't make many friends.
