Simple stuff to put together. Some tips:
- Lead acid batteries shouldn't be discharged more than 50%, so figure that in your expected power consumption
- AGM batteries shouldn't be discharged past 80%
- Lithium batteries can be mostly discharge, but cost a ton of $
- Golf cart batteries can be discharged a lot (read up on them) and purchased at Costco
- Solar panels are easy to buy (home depot, etc.). I have Renogy brand.
- Get a solar charge controller (Victron, Renogy, etc.). Rated for your power. MPPT are the best, but PWM are good, too.
- Get a good inverter - not a pawn shop one! The best are pure sine wave, so they'll power anything you have. The cheaper ones are modified sine waves, and that can jack up some electronics.
That's all you need (well, cables, of course).
Total up all your worst-case power consumption (total amp-hours) and pick your battery and solar panels based on that. Consider a cloudy day and how that might affect it. A 200W solar panel will only put out 100W on a party cloudy day. Much less than that on a cloudy day in the winter, etc.
