put it on battery and lights came on for a shot time and went off. could not get them to come back on checked the battery and it is o.k, Hooked it up to house current and every thing works.Am I missing something?

Is the switch itself bad? Did you blow a fuse in it?
Check the simple things first. Might be whatever senses the situation that the causes the unit to switch over to batteries is bad, but I'd be checking the easiest stuff first.

Sure the battery is ok? It may measure correctly without a load on it but the voltage can fall dramatically if it's not properly charged and it has a load - like the inverter - attached.

If the battery has a low charge then the input current to the inverter will increase as the battery voltage drops and when it exceeds certain limits the protection circuitry should kick in and shut it down.
