When you are plugged in your converter will supply your 12 v board with the amount needed to run what the demand is and the rest go to the battery until the battery is full and then will drop down the amps supplied. But you are still running off the battery. I'll attach if I can how to test it.
I haven't checked the link yet but will.
I muddied the water by mentioning the two 30's, in your case 40's, apparently. I didn't mean to, but thanks to all that have told me they only protect the converter in case of reverse polarity. That isng I did not know but thanks anyhow.
