What is the best inverter for at home that will give me min 4 hours of run time. I will be running my PC, fibre/router and 2 screens.
I am looking for something that isn’t too expensive but decent quality.

What power supply is in the PC? What type and size are the screens?

The inverter is the easy part, batteries are where the expense lies.

Assuming your machine uses 300W, screens 50W each and router 15W you will need about 450W inverter and 1800Wh of effective battery capacity. In other words, you will need about 300Ah of 12V lead acid batteries, which won't be cheap.

Nope 200Ah batteries would do it, not sure where you got 300Ah from?
 
That load will pull 40A on the 12V side. Consumer grade batteries I have seen usually list their rating for a 20 our period. So a 300A battery can reliably deliver 15Ah for 20 hours. I'd say go with Lithium Ion packs

It'll probably be more like 3 * 100Ah batteries in parallel delivering 12.5A each.

Lithium is definitely better, but pricier, and I got the impression from OP that price was a strong factor.

Also, it could be that OP needs quite a bit less power than the 450W estimate.

I actually don’t know. It’s my work PC so I didn’t do the build. It’s a powerful machine as it is used for graphics. A rough idea of what you think the set will cost?

Can you let me know what you think the entire set up will cost and what you think I should go for?
 
Thanks for all the responses. Unfortunately I have very little understanding of inverters and how they work. If you could all suggest a complete set up for me that would great

Something like this will do, but you'll need to add extra batteries.
