most invertors wont charge a bettery with no charge, so using a load wont work,
they also dont stop charging - they switch to tricklecharging al low current.
back to the problems,
transformers hum because they can move - tightening any bolts and maybe putting wax or epoxy on the windings can reduce it.
ticking or clicking could be a loosly wound inductor.
