There were no faults at the time I was there, but there was an OverTemp warning. I have not personally observed it with the F66 error, so I don't know anything else, but it stands to reason that eventually the warning reaches the level of a fault/error. I'm going to see what happens with the Inverter and Charger functions disabled. If it faults out again, I will just delete it from the system.</div><div><div dir="ltr" class="gmail_signature"><div dir="ltr"><br></div><div dir="ltr"><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">Thanks, everyone, for the help.

<div>If the bad inverter is the master. You will need to assign a new master. Since this is 1st generation XW you will need to use SCP and probably use the manual if you are not familiar. Rebuild the xanbus network.</div>
<div> </div>
<div>That is alot of loading and the usual warnings about heat killing electronics and the need of cooling down your way. Good Luck!</div>

<div dir="auto">I'm looking at an off-grid quad inverter setup for a client, not my installation. One of the stacked.inverters is extremely hot, sometimes it goes into F66 and takes down the adjacent inverters with it to F66 probably because of these Xanbus network is broken.

<div dir="auto">I disabled charging and discharging on the inverter that is getting hot, but it's still remains very hot. Any ideas? </div>

<div dir="auto">I tried to put that one inverter in standby, but the generator will not sync with the remaining three and charge the batteries. So I have to leave it in normal operating mode for the moment. </div>
