SOURCE: I attach my inverter with custom battery cables

please check the voltage of the battery may be the voltage of battery is low or use the multi meter and check DC volts before conneceting the battery and after conneceting once more check the DC volts it could slove the problem
the beeping sound is due to battery low voltage
what is the DC input of the Inverter check the battery hook up if the inverter is of example DC 24 volts please check what is the input

SOURCE: No power output from my vector 1000w inverter.

Buy a different brand of inverter. Yours has developed a short which the protection circuit is catching. It then tries a restart but fails all over again. Most likely o/p short which looks like an overload to the inverter.

I am thinking this a high impediance device problem and this is normal operation - the user manual of my inverter warns about use with high impediance devices - if not I am interested also...

DO NOT DO THIS! If I understand you correctly you want to have three ways to have 110 power in your motor home--- (1)Vehicle 12V to inverter to main panel. (2)Generator to main panel. (3)plug the main panel into 110V. If any two of these are connected at the same time and they are both live, somethings going to blow. That's because with AC, the two sources must be synchronized in their cycles very precisely. The utility company connects their power plants together on the grid only with the aid of precise controls. But the really serious problem is the same reason they invented transfers switches for home generators -- if you were connected to (3) and the power went out, and you connected (1) or (2) without disconnecting the dead (3), you will backfeed power to the line outside and you just might kill the lineman who is trying to fix the power outage.

If your not getting enough voltage to the inverter it will beep to let you know you don't have enough power. Most common cause is a lose connection thru your cigarette lighter. Also if you turn your key off it might be shutting down power to your plug.
Make sure you have a good connection with your battery or plug adapter. You also need a good battery so you don't go into a low voltage condition which will make your inverter beep.
