What I'm doing is forgoing a generator/power station.

If I understand this correctly, these are so expensive because they come with an inverter (the device that converts the Direct Current from the solar panels into Alternating Current, which is what our appliances use).

From what I've gathered I'll need need 300W of solar panel to directly power the PC, and those cost around $100 a panel, so that's $300.

Next I'll need a charge controller to mediate how much power goes directly to power my appliance, and how much can go into a battery. Charge controller is $20, and if I want to power my PC for a few hours, I'll need a battery like this, so that's another $380, and lastly I'll need the inverter itself, which I'm not sure which one I should get. For my experiment, I'll be using approximately 225W, so I'm guessing this 1000W inverter should be more than enough? If so that's another $190.

Altogether, that's an over $900 experiment which is something I'll likely keep anyway, and can be scaled up with more solar panels and batteries if we make the switch.

This and wondering if I can mix and match different components is what I'm having an issue understanding.
