I recently completed the installation of the matte black wall charger, I am a handy guy but I have to admit this project pushed the limits of my DIY skills. If folks are determined to do it themselves I would highly recommend a couple of things:
- look at a few DIY videos, especially ones that would be pertinent to your install, for example my install fed power from the bottom (as opposed to from the top or back)
- please read the manual, it's written in a bunch of languages but the actual number of pages in English are no more than 6 to 10 pages, there is important stuff you can miss like the dip switch settings
- this install calls for manhandling 6 gauge wire, I think of myself as a reasonably fit, athletic guy, but trying to attach 6 gauge wire to my basement ceiling (by myself) was on par with wrestling an anaconda, so please get a friend to help this install needs 2 pairs of hands
- recognize your limits and don't be afraid to stop if you are not comfortable with going further, for me I did over 80% of the install but I called my contractor buddy to hookup the wires at the charger and breaker panel. It wasn't that I didn't know how to hook it up but the strength and dexterity needed to bend, twist and insert 6 gauge wire in a very confined area in my opinion is something better left to the professionals. Same thing with the breaker, less of an issue since there is more space but maneuvering 6 gauge wire is challenging
- Final point, think very carefully about where you want to put the charger, in my case it was in my garage on the back wall. Find the spot that will be the shortest distance to your break panel, this will save on cost and minimize voltage drop. I my case the distance was 52 feet, I am receiving 48 amps and charging at 74kph, voltage on average around 241 - 243 (so little or zero voltage drop)
