The inverter button turns the inverter on/off (you want it off while on shore power).
The charger button turns the charger on/off (you want it on while on shore power).
Are you sure the shore power actually has power? check the breaker for the shore power plug.
In your coach, while on shore power, plug in something to see if you have 115V AC power to the plugs. If the inside plug works, then your shore power is good....
The green charge light should be on.
The green invert light should be off.
the panel will go to sleep...all lights off until you press the select knob. The it wakes up and the indicators will show what is happening.
