I like Schneider and I am sure you will like it too. Personally I am using AV http://www.ebay.com/itm/Nissan-Leaf..._Inverters_&hash=item3a76456540#ht_500wt_1416. Where you located?
it is plugged in and I know about evse upgrade. I'm still considering that. But since the GE was replaced under warranty I will continue to use it.Solangelist said:How is the GE charger connected to the AC? Is it hardwired in, or is there a plug into a 240v socket?
bowthom said:Hello,
Just wanted to chime in here. Mine was the first Leaf to suffer a diode failure of the charger in April 2011. If you look at the circuit diagram there is no way that the GE Wattstation can over power the diode. It is protected by circuits / components which limit current and voltage. About the only thing that could get in there would be a high voltage negative spike on the ground from a lightning strike (cause of the #2 failure in Tennessee). They tried to blame my TIG welder but the car was 30 miles away when it failed.
The only other possibility would be a static discharge not shunted because the ground pin on the J1772 connector is recessed and not connecting first.
I suppose if the contactor is putting out a sizable negative spike when disconnecting, that could have an effect if the circuits are not sufficiently isolated. But if that were true it would not have passed the UL tests.
Just my .02
Nissan replaced the charger under warranty.
sub3marathonman said:But if a different EVSE caused the diode to fail, that would indicate that it is more likely a problem with Nissan than GE.
Quite possible, although since almost all of the public EVSEs I'm aware of DO the diode check, I'd think most owners would find out sooner or later. Also, the recent failures tied to the Wattstation have also failed to charge on the AV and the supplied L1 units.jms said:My concern is this: If the AeroVironment evse and the 110 evse provided by Nissan do not do the diode check, then how would you know that yours had failed? It is possible that the diode has a high rate of failure but since AeroVironment and Nissan are ignoring that part of J1772 standard it goes undetected?

Dealer warns that using a GE Wattstation can damage your LEAF
Hrm.
Stone Brewery in Escondido has a commercial GE Wattstation. Haven't used it--yet. Wondering if I should.
The commercial unit appears to be completely different than the residential units. The Stone EVSE does hum very loudly when used, though. I know that many have used it without issue so far - I've only used it briefly as I didn't need the charge at the time.lonndoggie said:Stone Brewery in Escondido has a commercial GE Wattstation.

Thanks for that input. I tweeted them the question, they said they haven't received any complaints (and Koch drives a Volt, which doesn't seem to exhibit any problems).drees said:The commercial unit appears to be completely different than the residential units.
