Bolt on fuse

[Dennis 1]

Hi guys, my question is should I have a bolt on fuse at every battery? I have 3 - 12v - 100ah batteries hooked in parallel and I have a 200 amp bolt on fuse at the 1st battery before the inverter and 0 awg connecting all batteries. Any help with this would be appreciated.

Happen to have a pic?
All cells are in parallel but inverter connected to fuse on "first battery"? I cannot envision this, sorry.

I hope these pictures help

Thats pretty confusing with the red tape on both positive and negative terminals! Bit i got it figured out thanks to the shunt being there.

Hooking the fuse and load to one end of a parallel bank of batteries will result in uneven charging and discharging.
If you put the shunt/load on battery 3, it would be much more even.

So just move the shunt to the last battery ,do I leave the bolt on fuse where it is at? But do the other batteries need a bolt on fuse?

Fusing is to protect the wiring, not the load item (inverter) or the storage source (batteries). Fusing every battery would only protect your jumpers. You are fine as is, other than balancing battery usage as Mistersandals stated.

Thank you for the info I thought it was alright but just checking.

No, you REALLY should move the shunt/load to battery 3.

Thank you I did not know that, I'll move it over
