I would check the dryer for a ground fault, and I would check the system to make sure Neutral is not bonded to ground in more than one place (very common). Most importantly, I would make sure that negative is not bonded anywhere except at the DC GFI in the controller. My guess is that DC is bonded at the negative shunt as is normal with many DC load centers, and that the dryer is a big enough load that pulls enough DC amps, so that some of DC negative is flowing back through the ground. Probably doesn't trip normally, because at lower loads, less than an amp is flowing on the ground. Just guessing, Ray Walters Remote Solar 303 505-8760 On 1/14/20 7:03 PM, Mac Lewis wrote: Hi wrenches, I've got an off grid customer that has an external PV GFI breaker in his charge controller that trips when the dryer is on. He snuck in an electric dryer uggh However, I am curious what the mechanism might be to cause the trip. Will a ground fault on the AC side of an inverter trip a PV GFI on a charge controller? I haven't dug too deep into this yet but maybe someone else has seen this. Thanks in advance for your help. _______________________________________________ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.re-wrenches.org [3] Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org [4] List-Archive: http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html [5] List rules & etiquette: www.re-wrenches.org/etiquette.htm [6] Check out or update participant bios: www.members.re-wrenches.org [7] -- Links: ------ [1] http://members.sti.net/offgridsolar/ [2] mailto:offgridso...@sti.net [3] mailto:RE-wrenches@lists.re-wrenches.org [4] http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org [5] http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html [6] http://www.re-wrenches.org/etiquette.htm [7] http://www.members.re-wrenches.org
