Is my electric setup okay?

[kex02611]

Please let me know if this is okay, or if you guys have any feedback

The wires from the battery to the solar charge controller and the battery charger have no fuse.  I use fuses in my fuse box to connect those items to the battery.  Otherwise a short to ground on those wires could spark a fire.  

What's the box between the inverter and the outlet?  The text is unreadable on my phone.

Hard to read the drawing. But you do need a fuse for the inverter and a fuse for the charge controller. They will be different fuses as the cables are likely different sizes. You would be well served using a bus bar to connect different cables to the battery. Blue Sea makes quality.

In a combination with these fuses; https://shop.marinehowto.com/products/blue-sea-marine-rated-battery-fuse
Rule: fuses protect wires.

The resolution of the photo is too small. I tried zooming but it becomes too blurry to be able to read it.

[font=Helvetica, Arial, sans-serif]You mean i should use a bus bar to connect one cable from the battery posetive side and then split it to go to the VSR and Inverter and fusebox?[/font]
[font=Helvetica, Arial, sans-serif]I actually already bought a busbar from China [/font][img=20x20]https://forum.projectvanlife.com/images/emoji/apple/stuck_out_tongue.png?v=6[/img][font=Helvetica, Arial, sans-serif] do you think the quality is worse? and possible dangerous?[/font]
[font=Helvetica, Arial, sans-serif]thx for advise![/font]

Only you can judge the quality of something I have not seen. But in general, most boat, RV, and vehicle fires start with an electrical problem. But I use these for the battery connections. ie; battery to bus, fuse, to inverter. If the distance is long between battery and bus, a fuse may be needed. https://www.bluesea.com/products/2104/PowerBar_600A_BusBar_-_Four_3_8in-16_Studs

Going straight to the battery for large loads should be fine if it's only a few things but a bus bar will keep the cables neater and you won't risk running out of room on the terminal. Just make sure it's rated for more amperage than you'll use.

My solar maxes out at 20A so I just went straight to the fuse box.

50 amp fuse may not be enough on each side of the vsr unless it's a really small battery and/or small alternator. Get some higher amperage fuse holders and jump up to the next size fuse if you find you're blowing it when you're charging a low battery. I use ANL fuses, which seem common among car stereo nuts.
