Hi
My 12/500 has 3x35A fuses internal.
Does one just add the three to get the total internal fuse rating?
Many thanks

I am a little lost...why are you interested in the "total internal fuse rating" of the unit?
What exactly are you trying to fuse?
Hi, I am still new in this endeavour.
I was just wondering how the fuse setup works with three fuses.
I know that my fuse by the 105A battery needs to be 70A.
With three 35A internal fuses; will the 70A still blow before one of them?
Correctly fuse the wire from battery to your inverter based on the wire size...or use a good quality DC circuit breaker. The wire size should be stated by the inverter manual. I like to upsize the wire by one size. Example: if recommendation is 1/0, I go to 2/0.
If your batteries already have an on/off switch, great! If not, put a good BlueSea battery switch inline with the fuse. If you use a DC circuit breaker then no switch or fuse is needed because the circuit breaker acts as both. Don't fuse or use a circuit breaker on the negative side of the battery, it needs a clear path to ground.
Remember the fuse or circuit breaker is there to protect the wire.
The internal fuses are to protect the equipment and should not blue unless a catastrophic failure.
