NO FUSING ANYWHERE WITH THAT BATTERY!
Have you any idea what the fault current would be? toontra, please, please get a competent person on board
Just because it says 'protection does not mean anything at all
You should have a battery isolator and battery fuse with all cables rated for the fuse fault current, or individual circuit protection
Why cut corners when a few 10's of £'s buys peace of mind. especially somewhere you are sleeping
I have read the document below, as a design engineer this device correctly installed will be several orders of magnitude safer

Let's talk about a scenario just to make my point..
Install of 24-12 Volt DC converter in a big red fire truck. Installer did not read instructions, 'fit fuse of X amps rating'.' Unit failed fire appliance got filled with nasty smoke.
Two problems- Incompetent installer, and equipment not manufactured fail-safe with internal protection.
'If it can happen it will happen...'
I have a similar one and it's biggest problem is it trips *too* easily - it's sensitive to brief current spikes and relay flyback pulses
So, as expected it's a crap design.
