Inverter problem

[Tombola]

I have my inverter 2000w/4000 running from 2 KS energy 200ah (each) Lithium batteries. The inverter will run fine for the first minute using the micro wave or kettle, then beeps trips out, and then starts again for 5 seconds or so then trips, and keeps doing this.

The batteries have a max dicharge continuous of 150ah (each) and Im drawing 70 ah from them when using the microwave.
The inverter is linked with 35mm cables via a 250a trip fuse like the one below.
I stripped the cables and unscrewed the fuse so I could feel them in use, the cable didnt get hot but the fuse does...on the back side. You can touch it but it does feel hot.

My question is, does the inverter know the temp of this fuse, and trips because of that (the fuse doesnt trip) and what does anyone recommend to try and solve it. (apart from using gas to warm my beans and kettle )
It works fine for the first minute and if on lower wattage. DO i replace the fuse with a proper inline one maybe? I thought the inverter was faulty at first, till I swapped it with another.

thanks

The fuse getting hot is causing a volt drop and the inverter is tripping out due to low voltage.
Replace the trip with either a midi or mega fuse and all will be OK.

Those trips receive lots of poor reviews. Avoid and replace with a decent fuse as recommended by Lenny HB

fuse changed as advised, working a treat

Those are fire starters not fuses. It uses a rudimentary bi metal contacts to trip on thermal expansion, pretty pants. Not accredited either, so no reliable ratings.
