Im working on an application where I am charging a 12V battery with a generator that has 12VDC output. In order for the generator to charge the battery I need to close the contacts on my relay board using a signal from my microcontroller.
The relay is rated for 16A at 24VDC. the generator dc output is rated at 12v, 100w, 8.3 A. Do I need any type of protection in front of my relay even though the relay current rating is double the current from the generator? The relay board vendor recommends a fuse but i dont see why if the current from my generator is no where close to the relay current capacity.
If I do need protection would I use a current limiting circuit like the one I attached or is a simple fuse good enough?

Please advise someone.
