How to wire up a solar panel kit?

[GimmyTree]

Here is the solar charge controller with the wires and connectors that came with the kit: https://ibb.co/xLM72kS


This is the pure sine wave inverter with wires and connectors: https://ibb.co/VQJT3Sz

And the solar panel wire connectors: https://ibb.co/Qbb1CrW

I have one pair of mc4 solar panel connectors on order so I can connect the solar panel to the wires.
I assume the white wire (which is quite long and has positive and negative wires in it) connects to the solar panel and the solar controller, correct?

Do I need to buy positive and negative wires to run from the battery to the controller?  The solar kit I got doesn't seem to have those wires.
The kit was suppose to have come ready to set up, does it look like I have everything to setup the solar panel kit?  (battery is still to come)

you need a fuse box

basically,
panel + to controller +,panel - to controller -

controller battery + to fuse on battery + https://www.electricalhub.com/blue-sea-5191-waterproof-terminal-fuse-blocks?_vsrefdom=adwords&_vsrefdom=adwords&gclid=EAIaIQobChMI55qi-4u64wIVi5OzCh0dTQJLEAkYBCABEgJs3PD_BwE,controller battery - to battery -

battery + to fuse box +,battery - to fuse box -

electrical items/outlets wired to fuse box,fuses are matched to wire size https://vandwellerforum.com/thread-656.html

inverter and fridge wired to battery with their own fuse,the bigger the wire you can use the better
