Connecting multiple solar charge controllers to a single battery bank requires a distribution block to aggregate the charging current safely. When installing two controllers that cannot be placed near the battery, run individual positive and negative wires from each controller to a common distribution block.1:03 Install a dedicated fuse for each controller at this block, sized according to the specific controller's output, such as 10 or 15 amps.1:37 From the distribution block, run a single pair of larger gauge wire to the unswitched distribution point at the battery bank.2:26 Size this main wire to handle the aggregate amperage of all connected controllers.3:51 Install a final fuse at the battery connection point rated for the total combined current of the system.2:38 For installations with four or more controllers, use a multi-circuit fuse block instead of individual inline fuses to improve cable management and simplify troubleshooting.3:25 Always ensure the wire gauge and fuse ratings account for the total potential charging current from all controllers combined.3:58
