My 5KW Induction generator case is hot.

My 5KW Induction generator case is hot. I can put my hand on it for a few seconds but it's too much after that.

Is that about normal?

Im going to get an instant read IR temp gun, but need to know if I should be worried - this is my first year of full start up and run, past owner of the property is not available.

If possible try and use all 5KW as it is being produced, a few irons, hot plates, heater, etc. Run the system at 90% load for 6 hours and see if the temp goes down.
If it does, then you dump load needs to be looked into.

It is also possible that your current load is too high turn off every single thing in the house and see if the temp goes down.

It's a grid tied system. I spoke to my engineering helper and he advised that some of the power the gen is producing is going to be converted into heat. Apparently the norm is that the case will be hot enough to hold your hand on for a few secs. As the ambient temp rises so does the case heat. I'll call Marathon tomorrow but at least I can sleep OK tonight.
