With our old trailer the Solar Panel charge controller was the culprit 
to a similar problem. The LQ has two different power sources. The first 
is DC, lights, etc. The second is AC for the microwave, air conditioner, 
hair dryer, etc. Turns out a diode was bad with current leaking back 
through the wrong way to ground. By the inverter he probably meas the DC 
power supply or the AC to DC transformer. When the LQ is plugged in this 
supplies DC current for charging/maintaining the battery, running the 
lights, running the refrigerator circuitry, etc. The solar charger 
directly provides DC current through the controller. The controller 
locks down the current flow to keep it from overcharging the battery and 
burning it up. There is feedback from the batter to the controller that 
provides the information the controller needs to manage the current 
flow. This is through diode which allow current to flow one way - in 
this case to the controller - and not the other way. This is where my 
problem was and this resulted in a drainage of the battery to ground.

First thing to do is disconnect the solar controller and see if it 
works. Next if that isn't the problem is to look at the DC power supply.

There is either some sort of current leakage in your LQ or the system is 
not grounded properly. The best thing to do as Ed states is to find a 
good RV repairman - one that knows how to read a volt meter.
