    Positive side draining faster

    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...

    Positive side draining faster

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

    Positive side draining faster

    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

    Positive side draining faster

    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?

    Growatt 3000tl lvm-es N-G screw

    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?

    Growatt 3000tl lvm-es N-G screw

    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...

    Growatt 3000tl lvm-es N-G screw

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

    Growatt 3000tl lvm-es N-G screw

    I think I habe it all worked out now, will do some more tests next weekend to double check everything, mine were purchased from signature solar and support is very difficult, it's strange that watts247 didn't respond to you, I have emailed ajd called him with questions on equipment I didn't...

    Growatt 3000tl lvm-es N-G screw

    So they should play well together? My mind keeps going back to will prowse but maybe he had older units that didn't have dynamic bonding

    Growatt 3000tl lvm-es N-G screw

    How does dynamic bonding work when two units are wired in split phase and both units have the internal NG bond screw in?

    Growatt 3000tl lvm-es N-G screw

    I will test it another day, also I was curious if I have everything connected correctly so I used my travel trailer EMS to test it and I get no errors, it shows proper grounding etc, I disconnected my earth ground to see if it changed anything and I got no warnings, I'm guessing the NG bond is...

    Growatt 3000tl lvm-es N-G screw

    I have them running separate because of the issue of having current on ground when running AC input which is hopefully fixed now, if I switch to having them connected ad one unit for 220 do I keep the NG bond screw in both units? Seems to some confusion on this part from over a year ago

    Growatt 3000tl lvm-es N-G screw

    @timselectric I'm most likely over complicating things, just checking to make sure I'm understanding correctly. Add screws into both inverters, pull NG bond out of my breaker panel (not the house panel but inverter AC output panel.) With the NG bond bring done in the inverter do I need to...

    Even if I have no AC input the panel is considered a subpanel because the inverters are doing the NG bond now?
