<div dir="ltr" gmail_original="1"><div class="gmail_default" style="font-family: arial, helvetica, sans-serif;">My understanding is that the EV charger will be compatible with the SC3 but not the SC2. The <a href="https://mailtrack.io/l/90667185047385cae6914b7225cd28f5ef001880?w=cmUtd3JlbmNoZXNAbGlzdHMucmUtd3JlbmNoZXMub3Jn&url=https%3A%2F%2Fenphase.com%2Fdownload%2Fbidirectional-ev-charger-white-paper&u=1613865&signature=feaaf6fd1c1cbfdd">white paper</a> says that the system will require the CAN bus protocol, and I don't think the SC2 can be upgraded to use that wired protocol. The IQ Combiner 3 or IQ Combiner 4 should be usable with a Communications Kit (COMMS-KIT-2). However, When I am upgrading people to IQ Battery 5P where they have an IQ Combiner 4 or prior, I just upgrade them to an IQ Combiner 5C because by the time you buy the communication adapter and cell modem, it's cheaper and easier to just swap out the combiner in most cases. And that leaves me an older combiner to have as a spare to sell as a used replacement down the line.</div><div class="gmail_default" style="font-family: arial, helvetica, sans-serif;"><br></div><div class="gmail_default" style="font-family: arial, helvetica, sans-serif;">I think you are safe with the SC3 for bi-directional charging compatibility. I am not clear on whether a SC3G can be used. But I think the bi-directional chargers will use one of the DER breaker slots, which means you will need a SC3, not a SC3G if you also have 5P batteries. That means you will be limited to four 5P batteries without PCS or 8 batteries with PCS.</div><div><div dir="ltr" class="gmail_signature"><div dir="ltr"><br>Jason Szumlanski<div><span style="color: rgb(51, 51, 51); font-family: Roboto, RobotoDraft, Helvetica, Arial, sans-serif; font-size: 13px;">Principal Solar Designer | Florida Solar Design Group</span><br style="color: rgb(51, 51, 51); font-family: Roboto, RobotoDraft, Helvetica, Arial, sans-serif; font-size: 13px;"><span style="color: rgb(51, 51, 51); font-family: Roboto, RobotoDraft, Helvetica, Arial, sans-serif; font-size: 13px;">NABCEP Certified Solar Professional (PVIP)</span><br style="color: rgb(51, 51, 51); font-family: Roboto, RobotoDraft, Helvetica, Arial, sans-serif; font-size: 13px;"><span style="color: rgb(51, 51, 51); font-family: Roboto, RobotoDraft, Helvetica, Arial, sans-serif; font-size: 13px;">Florida State Certified Solar Contractor CVC56956</span></div><div><font color="#333333" face="Roboto, RobotoDraft, Helvetica, Arial, sans-serif">Florida Certified Electrical Contractor EC13013208</font></div></div></div></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Apr 3, 2024 at 7:57 AM Mac Lewis via RE-wrenches <re-wrenches@lists.re-wrenches.org> 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="ltr">Hello Wrenches,<div><br></div><div>I have a customer who is an early adopter that is ready to add some Enphase 5P to his IQ 8 system.
