    Firstly thank you guys for your great info, I am trying to troubleshoot a problem with my set up and this has been helpful. I do have some questions though as my system is slightly different.
    I have a solar set up going to battery bank. Batteries connect to solar regulator, regulator to inverter and inverter to panel. There is also a generator that powers the panel when solar is not connected, as well as charges the battery bank.
    The panel is wired with 1 hot, 1 neutral and 1 ground. With three beakers that delegate the power through the house. No ground rod..recently while using the solar, the system got overloaded when I plugged in an electric chainsaw battery charger to breaker #1.It seemed to fry the inverter, and I have since replaced it. However breaker #2 does not worked with the solar now and shuts off the new inverter when the breaker is switched on. It does however work with the generator(which bypasses the inverter) I've checked the connections on all of breaker #2' outlets, and nothing is showing any signs of arc. There was a section of wire that had been chewed by mice and touched hot to ground potentially, but I replaced the wire and it is still shutting off the inverter. Any thoughts? And I apologize for the lengthy explanation. Thanks!!

     It looks like your inverter is connected to your load output from the charge controller. If so that's your problem. You MUST connect the inverter directly to the battery bank with appropriately sized cables.

    2.1 Kw Suntech 175 mono, Classic 200, Trace SW 4024 ( 15 years old  but brand new out of sealed factory box Jan. 2015), Bogart Tri-metric,  460 Ah. 24 volt LiFePo4 battery bank. Plenty of Baja Sea of Cortez sunshine.

    Is the inverter a mod sine or pure sine wave ?   Only pure sine should be wired to a grounded panel with hot+neutral wiring.   Mod sine inverters seldom have an isolation transformer
