At the moment I have a fuse on the positive battery cable only. My question is, Should I fuse both the positive and negative cable between the Mppt & battery? Can anyone advise on an ideal switch/fuse to use? I currently have a midi fuse installed
One fuse on the positive side is enough. The type of fuse depends on the battery voltage and the charging current. I have a 12V system with mega fuses on the Victron MPPT chargers
