Weird discovery that I never noticed before, I turned the mppt off and with only the inverter on I am pulling .60 amps from the top battery (lowest of soc) and 0 amps from the other two batteries, switched cables around and battery 1 is still showing amp draw while others show 0 while inverter...

Sure, I can spin it around I guess, just thumb screws that I torqued with pliers, guessing around 20 or so NM

That's my next step but need to make a new cable so I can, my OCD took over amd I made everything the exact same length so when i make a new cable it will be about a foot longer then the other

I have three 48 volt rack mount batteries, for some reason the battery that is connected to the positive side drains faster, any reason why?

Trying to figure out if i should try for replacement units just incase, I wasn't sure oif the relay was stuck etc since no NG bond screw was installed, seen lots of people running common neutral with NG bond screws removed to fix some issues, this has all become a huge nightmare

What kind of damage would have happened with the NG bond screw removed on both units running split phase or single phase? Any shortened life of the units?

So what about the NG bond in the panel? No grid AC input add NG bonding screw in my panel, when running AC input remove the screw? Or leave the NG screw out of the panel at all times?

This isxa response I got from signature solar " The inverter does not create a Neutral-Ground Bond; it creates a path to the Neutral-Ground bond in the panel via the Grounding Screw and an internal relay. Not making the system bond in the panel will eventually damage the system from...

I have recently found out the the lvm-es has dynamic bonding so thebNG bond screws remain in the inverters themselves

Very strange
