Whelp, last night both inverters shut down after the Fault 61 showed up and wouldn't clear. SP1 was in EG4 mode, SP2 in USE mode, I have the corrected cable in the correct orientation. I've had intermittent 61 codes, but they've always cleared within a minute or so, setup has been running fine...
When charging, they're really loud. Not bad at 20-30% load only (not charging). Haven't pushed them much harder as of yet, but I'm guessing the fans will also ramp up at higher load amounts.
My 6500's in split phase can handle my Dryer without issue with a 19k btu mini split running at the same time. Also have a well pump ( 1/2 submersible) I'd like to connect. Based on how I've seen these performing, I'm confident it could handle it. But I'm leaning on installing a soft start...
Closest thing I've found. I know Growatt and the EG4's share the same DNA, but it could be different issue altogether. Will have to wait on Solar Signature.

Same issue with one battery one inverter and multiple inverters (split phase) and multiple batteries. Although issue seems to happen less since the batteries have been cycled a few times. USE setting gets rid of it until they find a fix.
New system I'm putting together with 6500EX's and LP4 batteries. I only had one 6500 with one battery for a few days fiddling with it but kept getting 61 error. Checked my com cables, but they seemed to be pinned correctly. Most of the time it indicates it is communicating with the battery...
Double checked pin orientation, made sure com cable was plugged into correct ports and had the lovely error 61 code this AM. I only have one battery connected at the moment minimal to no load. Same thing happened yesterday morning. Not sure if there's a pattern developing.
Definitely...
Appreciate the reply. Double checked the orientation, all seems okay. Looks like it's loosing coms with the battery. Battery indicator stops blinking when the error codes shows up. I unplug and replug com cable, error goes away and battery icon starts blinking again indicating good communication.
