Solar controller question

You will need to wire your single or dual controllers to a fuse block within 6" of the battery to meet ABYC. From the fuse block to the batteries use #6. Use a 60A fuse.

Got it. Thanks.

What kind of fuse block are you talking about? Iíve searched around but donít know what Iím looking for really.

So would I run four #6 wires from both controllers to this fuse block, and then two #6 wires to the battery bank? Does it matter how I hook it up to the 4 battery house bank?

Sorry for all the stupid questions, but Iím pretty stupid when it comes to this stuff. [emoji30]
