Which switches and fuses to use in solar panel / battery / load setup

I am wondering which switches (to disconnect) and fuses to use in my solar panel / battery setup.
I have got a 170w Solar Frontier panel (87V nominal, 2A nominal current) and a 75ah optima battery. My usage is no more than 25A current (300watt): 15watt ledlights and 60watt laptop and sometimes a 300watt pure sinus inverter
I would say:
- A switch and fuse between solar panel and charge controller: which one?
- A switch and fuse between battery and charge controller: which one?
- A switch and fuse between battery and load: which one? (something like this?: http://accuweb.nl/accu-toebehoren/massa-schakelaars/massa-schakelaar-12-24-volt-100-a/).

Hi Louis,
Generally a DC-rated Circuit Breaker does the job well. The following are DIN-Rail mount breakers:

These Panel Mounts are also nice:

Boxes for the above breakers;
Din rail with enough room for 4 or so breakers:

A very small Din rail box for two or perhaps three breakers, but it can be very tight, especially with larger cables:

Panel mount box:

The above products are what are in use here, they work great, and the breakers and boxes are usually Code compliant and are inexpensive.
