For a small solar system like this you probably don't want to use an inverter. The battery has a max 10A DC output which limits you to maybe ~100W inverter and idle losses will drain the battery fast.

Instead, you could use 12V DC lights connected to the battery or the controller load output.

Re: use cases - mostly outdoor

Important: both the controller and battery do not appear to have low temp cutoff protection. For year round use in all but the warmest climates, get the kit without the battery and get a battery with low temp cutoff protection.

- interior lighting, small fans, USB for a shed or low voltage landscape lighting
- front gate opener & ring camera
- gazebo fairy lights / device charging

I've been interested in a solar solution for lighting the inside of my shed. I'm not trying to be Colin Furze, but I just want to have some light so I can put away my tools at the end of the day.

Would a kit like this do that?

I use a simple ~$30 solar outdoor light inside my shed, just ran the cord through vent and mounted panel facing sky. It's motion sensitive and kicks on when I walk into the shed. Here's an example light https://a.co/d/gfkD0yl

OK - this is no where near a car battery size! This is just 10Ah - Rough numbers: The solar panel is 25W which means it can charge at 2Ah in full sun which means it will be charged most days. You should find some DC lights and you will be fine. A 100W equivalent LED is around 12Watts which will run 8-10 hours on this setup without sun and double that with sun.
You should really do your own testing and purchasing before you shill up the post. The power setup is equivalent to a car battery and you can easily swap out a more powerful car battery, making this a useful purchase.

If you don't use an inverter, you're using the most inefficient form of lighting there is. Sure, your big lifted truck might be able to tow a boat, but its not going to do it for the same distance as any other normal and more efficient car on the road for the same gas. Some "solutions" are easy, and therefore attractive, but STUPID if you're actually trying to use the setup. If you think for a moment that this thing will last powering WIFI for anything longer than an hour, you need to go back to school.

I don't need the battery - any solution for a solar charger to trickle charge my boat sitting in the yard?
There was a 7.5W solar trickle charger on sale the other day for much cheaper, but yes, this will work with other batteries, per my post.

Sorry- Electrical Engineer and solar designer for over 20 years so I come equipped to share some knowledge. This is a UPS battery size - a car battery is very different, this does not have starting amperage and a typical "car battery" is 40-100 Ah so 4-10 times larger. I didn't "shill up" the post and I have had similar setups for remote cameras so yes, I know what I am talking about.
