First post--Appreciate the forum, learning a lot, however I'm in need of some guidance on setting up a small system for a shed and outbuilding. I'm running into some questions. First off, this system is for utility and occasional use. It will not draw power with the exception of a motion sensing flood light that is on a 5min timer. By occasional use, I mean some to all of the loads listed below drawing power perhaps 3-4 days per month and only for 4-5 hours per day. Based on those loads, I'm not sure if it's worth spending a bit more or not, if a pure sine wave inverter is needed, or if I can make due with a lead acid 12v 50-ish amp hour battery or if I should be looking at deep cycle lithium or 100 amp hr batteries to scale it up in the future. There are some smaller "systems" from Northern Tool and Harbor Freight that people have suggested, but I'm not convinced on their quality although the reviews on the 100w panels seem decent.
Loads:
4x 11w LED floodlights
4x 5w to 8w LED bulbs
1x 12w LED work light (infrequent use)
1x Laptop charger (infrequent use)
1x 1.5 amp 120v Bathroom fan/light (infrequent use)
1x 120v 18" industrial fan -- I believe this would be the largest draw in summer
Looking for suggestions on a packaged system or the components to include panel(s), charge controller, battery and inverter. Here are some of the products that were suggested to me by a neighbor:
Panels https://www.harborfreight.com/100-watt-monocrystalline-solar-panel-57325.html
Carge controller https://www.amazon.com/SUNYIMA-Cont...sprefix=charge+controller,aps,116&sr=8-5&th=1
Battery https://www.amazon.com/ML55-12-Batt...amp+hour+solar+battery&qid=1663876119&sr=8-29
Inverter https://www.amazon.com/BESTEK-Inverter-Converter-Charger-Listed/dp/B07JJSW48V/ref=sr_1_18?crid=JQ6ECL9592YC&keywords=solar+inverter&qid=1663876506&sprefix=solar+inverter,aps,103&sr=8-18
Or would I be better off with a kit of this type, or similar:

I'd like to keep my total budget around $400-500 and have the option to add another battery in the future, if needed; to keep initial cost down. I belive I need 100-200w in panels, 2x 30 amp hr batts or 1x 50-70 amp hr batt, and a 500w+ sine wave inverter/charge controller. All the loads will be plugged directly into the inverter or via extension cord (50' max length). The shed is not insulated and not heated/cooled, only 80sf so space is limited. Final question; should I add a fusible link or in-lin fuse and if so, where?
Greatly appreciate all the help and any guidance. -Mike
