Re: Sailnet - critique my solar project.
Breakers or fuses are there to protect the wire in a short circuit situation. There should be a breaker or fuse in the positive wire between the controller and the battery, close to the battery post. There is no need for a breaker or fuse between the panel and the controller.
The threat in a short circuit is from the batteries, not the panel.
