    I’m going to guess as follows:

    Yellow caution light, not the end of the world, but something needs to be addressed.

    Maybe the inverter output is below or above specs?

    Well inverters make 120 volts and if it only comes on when the inverter is on my guess is its just a light telling you the inverter is switched on.
