    Put a fuse between the battery & the regulator, as close to the battery as possible. It's purpose is to protect the wiring from getting too hot & causing a fire in the event of a short circuit. It's rating needs to be higher than the regulator's output so a 25 amp or 30 amp one will suffice in your case. Best not to use a standard auto blade type fuse, (they can become a fire hazard themselves over time when used in this type of situation). A manual resettable circuit breaker is a good idea as it allows for disconnecting the panels too. Auto reset fuses/circuit breakers are a lousy idea as I found out recently. They can make fault finding far more difficult than it needs to be.

    No fuse required between panels & regulator.
