12v is better for RVs and smaller power draws. 48v is better for off grid, or anything that will use 1000+ watts at a time. You can wire them to do the same things, but then you have to wire in series and balance/manage etc. Easier to just buy 48v batteries if you need them.
12v batteries will technically work with large power draws, but you'll need much bigger cables to do the same thing.

I believe this will be a 24v system. Decent starter battery capacity. Can run a fridge 24/7 and few household items as long as it's sunny.
Yup. You could run a fridge for about 4-5 days on this with no sun... And with a little daylight, indefinitely. Full sun every few days and you can easily run the basic appliances, etc... it's 6700wh of battery
Technically, the solar inverter they are selling is 24v and not 12v, so you would be wiring the batteries in series. The lower the voltage, the higher the current for the same wattage, the thicker and more expensive the cables. However, if you can keep your batteries close to the solar inverter, cable runs should be short, and the increased cable costs should be more than offset by the much cheaper price per kwh for 12v batteries, at least with eco-worthy's stuff. The 48v system they sell has higher AC output and battery charging rates, which become more relevant if you plan to get more batteries. Also, you should check the price of the items individually on eco-worthy's eBay page. I've noticed sometimes the bundle is not cheaper than the sum of its parts.
Check the solar panel production and offset is to average out a year worth of electricity usage and reference with how many panels you will need to cover your usage.

Higher amperage requires heavier gauge wiring.
So if you are doing 48v, the amperage can be low, and you save on copper.
