<div dir="auto">William, I don\u2019t think the fm100 will be visible unless you reboot the whole system with inverter attached to port 1 of hub, mate3s attached to mate terminal in hub and fm100 plugged into port 2 of hub. I\u2019ve done this numerous times and you can program the fm 100. However, I have never left an fm100 without a mate3. Not sure if the charge controller will just keep running blind when you unplug the mate 3s. You could try it and see if if it shows charging on a trimetric or with a clamp meter. Yes, a mate3s and fm100 and hub is quite a financial bite when just looking for higher voltage or higher amperage controller. </div><div dir="auto"><br></div><div dir="auto">John Blittersdorf</div><div dir="auto"><br></div><div dir="auto"><br></div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Oct 17, 2020 at 10:11 AM Bradley Bassett <<a href="mailto:bbassett2@gmail.com">bbassett2@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>I think there is a jumper in the FM100 that will allow the Mate3s to communicate with it.
