True at $139 is fair, but at $99 I'd get 2.

Can it be used in a shed just for lighting especially in winter time?

Not advisable unless you live in an area that doesn't see below-freezing temps much. LFP batteries don't like operating (charging in particular) in below-freezing temps.

I would think you'd be ok for just lighting. Battery won't last as long in winter, but might be ok, and would be fine most of the year anyway.

Just get solar lights on amazon. I got some at costco, the solar panel is connected by a wire you can mount on the roof and then put the light inside

for fridge you'd really want 120v houshold equivalent 15A AC output (not a river series) and suggest minimum 1kWh capacity power station (like a delta series) for any reasonable minimal runtime. Fridge don't consume that much but when compressor kicks in can surge.
furnace depends on specs but you'll likely need something with higher output because of the surge/spike

I had the same problem. I had to create a guest network separately and it connected. I think it can only connect to 2.4 GHz and it got confused if you have both 2.4 GHz and 5GHz available
