Ok, now that I have my DC hooked up (thanks to everyone here), I am ready to move on to my AC hookup. As you can see in the picture, someone before me maxed out the panel and installed a sub panel. The easiest thing to do would be just throw a 40a in the sub panel and be good to go. However, the more I read about bonded grounds the more confused I become. I have removed the sub panel cover before, and I can verify the grounds and neutrals are bonded in there. I have read about removing the bonding screw in the LV6048 - I am just not sure this is the situation to do it. If I am reading it correctly, I think I remove the bonding screw in the unit so that the only bond is in the subpanel. Correct? Thank you
