White solid wires are normally neutral wires. Ground wires are bare copper or green. There should be 2 buss bars, one ground and the other neutral. Be sure you are connecting to the right one.
A picture would be helpful of course. Best guess on the transformer is part of the power convertor. May be there to reduce 120 volts down to 12 volts. It would feed a rectifier to change AC to DC. Ultimately charging batteries feeding house 12 volt circuits.
