    Wire ripped out of panel junction box

    If if he was able to pull the wire from the crimp, the crimp was bad in the first instance.

    Wire ripped out of panel junction box

    Open the junction box. Carefully remove any potting material (like caulk). Unscrew the old crimp lug. Clean the mating surface. Cut back the cable end. Strip. Crimp new lug Wipe with isopropyl alcohol. Reattach with screw. You cannot reinsert a wire into a crimp lug. That will never ever work.

    Chinese inverter discharges batteries without anything connected

    No, you don't have the settings set correctly. User error.

    The Will 3000 Hand Truck System, 2024 CES, Started buying used panels 3 years ago..

    Will's 3k inverter is ~ $700. Weighs about 25 pounds. Sol Ark is ~$7000. Weighs about 200 pounds. So, I don't think it is remotely reasonable to expect anybody is trying to put Sol Ark capabilities into EG4 3k box. Probably not possible.

    10w lost. But where???

    Measure each with an independent meter. DMM. These devices are not NIST calibrated.

    ..Or... that's the max the solar panels can produce.

    Newbie to the forum please be gentle

    This is a math question that requires specs of existing panels, specs of new panels, and specs of the 'inverter'? to which they are going to be attached. Is this a grid tied system? Does this system have batteries?

    Question about the solar tax credits

    IRS Form 5695. ...Costs. For purposes of both credits, costs are treated as being paid when the original installation of the item is completed... Completed. Ie commissioned. You can't get a tax credit for a pile of solar stuff you bought this year if you don't hook it up and make it work...

    Low Battery Inverter Shutdown

    What? The inverter is turning off on low voltage not because it was commanded by some closed loop something something. And Opie thinks he's still at 73%. I'm saying that's not correct. SOC is an overlay to make it easy for people to understand percentages the underlying actual science of physics...

    Low Battery Inverter Shutdown

    When was the last time you saw 14 volts or better? I think your shunt needs calibrated. 13.09 volts is definitely not 73%
