    Will a new inverter do?

    Do a little research into those particular BP 4175B panel. They were pretty much the reason BP went out of business in the PV world. They spent billions replacing their systems under warranty due to faulty J-box design. If there's any way to do an extended load test this may show the production...

    This, or that, or wait, maybe that?

    Aside from the time it takes to top balance the cells a 16 cell, 48 volt battery, it takes me a couple hours to assemble. Granted, I've built a few batteries in the last couple years but I have to say, your remarks are only going to dissuade people from doing the DIY approach and they aren't...

    Extremely overheated BMS, fused Breaker and dead Inverter. What could be the root cause?

    And of course it's stainless steel which magnets won't work on.

    This, or that, or wait, maybe that?

    Seems a 48 volt AIO and a single 48volt rack mount battery would allow easy expansion and keep you in that buy once, cry once mode

    4 X class solar flares to impact this weekend.

    If this flare becomes problematic, I'm sur we'll hear all about it right here after it's over.

    Series and parallels

    2 panels in parallel into each of the MPPT's

    Does this affect off-gridders as well?

    Extremely overheated BMS, fused Breaker and dead Inverter. What could be the root cause?

    Explodey, Funny word. Must be a technical term. Anyway, as to BMS's, My main house battery runs a daly 250 amp, "dumb" version. It seems to be working fine as I haven't had any issues so far 2 1/2 years in service now. We do get a lot of lightning down here in the summer and so far, so good...

    Dielectric grease on cable lugs? Lets test!

    Was that the name of your boat? :oops:

    My Signature Solar Experience (not good)

    Of course they are. Hopefully the inverter holds fault data such as excess voltage or a polarity issue upon connection.

    Has installer error been ruled out yet?

    Please review my off grid solar diagram

    2 volt batteries are generally high amp hour rated for building larger banks with minimal parallel strings. Yes, series wire 6 at a time for 12 volts nominal. You have gotten plenty of good info from others here so no need to cloud the waters with more of the same.

    Battery draw down at night?

    79 - 81% typical all spring long. no cooling or heating loads yet. Likely lower as it heats up.
