Hi there , hopefully someone can help me figure out what's wrong with my setup and why my 40amp fuses keep popping. It seems to be only the fuse on the positive cable that keeps popping.

Hi Herwig, As far as I remember, fuses should be 25% than the maximum load : 100A => 125A fuse, you inverter is pumping up to 125A to provide 1500W !! so I'll recommend you installing a 150A MEGA fuse.
I use a 3kVA inverter at 24VDC, and my fuses are rated at 125A, never had an issue. Before I was using smaller ones, and they did blown up.
Give it a try.

thnx for your advice! I was going by the 35amp MPPT... doesn't that have to be protected with a 35amp fuse?
