Ewarnerusa is it easy to see if removing the sense wire temporarily will reduce alarming in the inverter? If it eliminates it entirely, it might even let you sneak the set points up a bit. I believe having voltage correction will amplify the effect of a voltage jump caused by a reduced load, due to the change in voltage drop on your main charge controller wires, before the load drop and after.
Any rough estimate on how long those 4 gauge charge controller wires are? .01v at what current flowing? The voltage difference from controller to battery will approach 0 as current drops to 0, but be larger with more current flow. This is the effect i am talking about that can exagerate the voltage jumping when using a sense wire and a controller that is a little slow on the draw with voltage correction. You posted a .1v drop before. Was that with more current flowing maybe?
