Re: Unable to charge my 2015 Leaf from my solar panels - Hel

Problem Solved - - - -

Many thanks for the feedback. I pounded a new grounding rod (8 ft copper) and connected properly to the source (inverter) and also into the circuit breaker panel per code. Apparently, this upgrade vs. just grounding through the welded metal hangar satisfied the electronics. The GFI plugs tested well both before and after the upgrade. Yep - - the Leaf is sensitive about that ground and also the neutral.

First test (today): 65 minutes of level one charging (120v) gave me an additional 6 miles in the car and was easily handled by the off-grid system. With luck, I should be able to get about 50 miles per visit when I plug into my fully charged system. Hey - - - that $1.20 of "free" electricity will more than pay for my senior coffee (54 cents) at McDonalds!

Driving on sunshine,
Nelson

In the process did this bond the neutral and ground? I don't see how adding a grounding rod would make any detectable difference to the EVSE.

Glad it's working now!

As before (and after) the new grounding rod installation, the neutral and the ground are bonded at the main electrical panel.

Another tip for those who may follow - - - the car seems happier with an additional 75 to 100 watt load being applied to the system while it is charging. I just plug in a lamp with several light bulbs and I am good to go. A 40 watt (incandescent) bulb by itself doesn't seem to make it happier, but a few watts added above that and the system smooths out nicely while the car charges. Done!

Charge safe, my friends.

The DR series inverters aren't sine wave inverters, and I am a little surprised that the car charges well on its output. Nice to hear that the Leaf might be fussier about grounds than the quality of the AC power.
