I posted this on the TED forum, but since many MNL members use the TED with their LEAF, I though I would post here as well.
I just installed my new TED5000 this past Saturday. I installed 3 MTUs; one for the house (Load), one for my solar array (Generation), and one for my LEAF (Load, electric vehicle charger). I installed all of the MTUs in my main breaker panel (not the sub-panel with all of the house circuits) because that's where my solar and LEAF tie it. Everything works great until I start charging the car. At that point the gateway stops receiving any packets from all 3 MTUs. As soon as the car charger is turned off, everything immediately goes back to normal. I tried disconnecting all the red wires from the MTUs for 'improved signal strength' per the manual, and things started working again, for a while. I had to change all of the MTU calibrations from 1.0 to 2.0 to get the right readings though (I assume that's a side-effect of disconnecting the red wires?). When I did that initial test, it was early evening so the solar array was not producing much power. This morning, I tried charging the car while the solar array was producing 2.5 kW, and the same thing happened again (no packets received by gateway while the car was charging). I don't know for sure that the solar array has anything to do with the problem though.
It sounds to me like I need an inline filter between the car charger and the panel? Can I buy such a filter at Radio Shack, or do I need to order it from TED? Do I need one filter for each phase (L2 charger)? Is there anything else that could be causing this before I go out and buy filters?
Have any other LEAFers had a problem with line noise from the LEAF's charger? I do see at least one reading (3.666 kW) from the LEAF MTU before the traffic stops, so it seems that the problem is just the MTU -> Gateway communication.
Thanks for any help!
