They have caught us off guard more times than I care to admit. It's really hard for ESS systems since there are almost no products that run at 120/208v. But, anyway, the dead giveaway is that the utility meter type is different. We've been selecting the newer Enphase IQ8HC micros that are compatible with 120/208v. We've never had luck getting the utility to switch the client over to 240 v although we have tried.</div><div><br></div><div>At least in our neck of the woods in CA, Form 2S CL200 meters are used for 120/240v services (Also, Form 2S meters are used for 120/240v 320 A services)</div><div><br></div><div><img src="cid:ii_m2ditpa00" alt="image.png" width="562" height="511"><br></div><div><br></div><div>And Form 12S CL200 is for 208/120v services:</div><div><br></div><div><br></div><div><img src="cid:ii_m2diu84m1" alt="image.png" width="562" height="476"><br></div><div><br></div><div>Good luck with your fix.</div><div><br></div><div>Best, August</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Oct 17, 2024 at 5:58 AM Mac Lewis via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org" target="_blank">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">Hi Dave,<div dir="auto"><br></div><div dir="auto">Yes, we have run into this.

I was confused when checking phase for consumption CT's when I found that there was 120V L-N, but 206V L-L. I went and found the transformer, and there was in fact one transformer for all the houses that I could see. It had 4 wires coming out of it, and each house was tapped onto 3 of them. So they actually are just using two legs of a 3 phase 208/120V distribution system.<div><br></div><div>Has anyone seen this sort of thing before? I was amazed that a bunch of houses there all have 208V L-L, and it seems to not be causing problems. Granted my friend says his A/C is really weak and that they have had some funky problems with their electric oven. But they also just moved in last year, don't have many 240V (or 208V) appliances, and are not very electrical savvy, so they were clueless about this.</div><div><br></div><div>Unfortunately this means that all the Enphase IQ8A's I just put on their roof are useless, unless I go back to put in a transformer or get the utility to do something about it. I am going to call the utility (Con Ed), but I was just curious if anyone has had a similar experience and whether their utility was open to changing it to 240V.</div><div><br></div><div>Cheers,</div><div>Dave<br clear="all"><div><br></div><span class="gmail_signature_prefix">-- </span><br><div dir="ltr" class="gmail_signature"><div dir="ltr"><br style="color:rgb(34,34,34)"><div dir="ltr" style="color:rgb(34,34,34)"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"></div></div></div><div dir="ltr"><table cellpadding="0" cellspacing="0" style="border-spacing:0px;border-collapse:collapse;color:rgb(68,68,68);width:525px;font-size:11pt;font-family:Arial,sans-serif"><tbody><tr><td width="125" valign="top" rowspan="6" style="padding:0px 10px 0px 0px;font-size:10pt;border-right:1px solid rgb(236,189,0);width:125px;vertical-align:top"><a href="https://www.sungineersolar.com/" style="color:rgb(51,122,183);background-color:transparent" rel="noreferrer" target="_blank"><img border="0" alt="Logo" width="105" src="https://sungineersolar.com/wp-content/uploads/2019/08/Logo-Image-Only-1.png" style="border: 0px; vertical-align: middle; width: 105px; height: auto;"></a></td><td style="padding:0px 0px 0px 10px"><table cellpadding="0" cellspacing="0" style="border-spacing:0px;border-collapse:collapse;background-color:transparent"><tbody><tr><td valign="top" style="padding:0px 0px 5px 10px;width:400px;vertical-align:top"><span style="color:rgb(236,189,0);font-size:11pt;font-weight:700">Dave Tedeyan, P.E.<br></span><span style="font-size:11pt;font-weight:700"><font color="#ecbd00">Owner | Sungineer Solar</font><br></span></td></tr><tr><td valign="top" style="padding:5px 0px 5px 10px;font-size:10pt;vertical-align:top;line-height:17px"><span style="color:rgb(236,189,0)"><span style="font-weight:700">p: </span></span><span style="font-size:10pt;color:rgb(0,0,0)">he | him | his</span><span style="color:rgb(236,189,0)"><span style="font-weight:700"><br>a: </span></span><span style="font-size:10pt;color:rgb(0,0,0)"><a href="https://www.google.com/maps/search/1653+Slaterville+Rd.+%C2%A0+%7C%C2%A0Ithaca,+NY+14850?entry=gmail&source=g" target="_blank">1653 Slaterville Rd.</a></span><a href="https://www.google.com/maps/search/1653+Slaterville+Rd.+%C2%A0+%7C%C2%A0Ithaca,+NY+14850?entry=gmail&source=g" target="_blank"> </a><span style="font-size:10pt;color:rgb(0,0,0)"><a href="https://www.google.com/maps/search/1653+Slaterville+Rd.+%C2%A0+%7C%C2%A0Ithaca,+NY+14850?entry=gmail&source=g" target="_blank">| Ithaca, NY 14850</a></span><br><span style="color:rgb(236,189,0)"><span style="font-weight:700">w:</span></span><a href="http://www.sungineersolar.com/" rel="noopener noreferrer" style="color:rgb(51,122,183);background-color:transparent" target="_blank"><span style="font-size:10pt;color:rgb(0,0,0)"> www.sungineersolar.com</span></a><br><span style="color:rgb(236,189,0)"><span style="font-weight:700">c:</span></span><span style="font-size:10pt;color:rgb(0,0,0)"> (607) 270-0370</span></td></tr></tbody></table></td></tr></tbody></table></div></div></div></div></div></div></div></div>
