I think the Goal Zero 1250 is something like $1600 last time I checked.
It only has 2, 30W solar panels and runs to a 100ah AGM Lead acid battery.
A deep cycle lead acid battery you should only use at most 50% of its capacity IF you want it to last more than about 2 years. and should never discharge more than 80% max.
Pretty sure with those 2 panels it would take something like an average of 50-60 hours to fully charge it from say 80% discharge.
and keep in mind you are only going to get maybe at best 10 hours of charging per day and only about 5 hours of that at anything close to the rated W.
and even that is going to change drastically depending on where in the country you are located, what time of year it is, what the weather is like and how perfectly aligned you have the panels faced directly at the sun.
So you are talking DAYS to recharge it and its just a 100ah battery of which you should only use about 50-60ah of.
Depending on how much power you need and for how long you need it is what you need to figure out first.
Myself I would go with a LITHIUM battery, they recharge faster, weigh less, can safely be discharged as much as you like down to 15-20% with no ill effects, do not need to be charged to 100% full either.
In fact they are better off if you don't.
You just have to make absolutely certain that you do NOT at anytime discharge it to ZERO or you could kill the battery for good.
If you buy FOUR of these "cells" you can make ONE 12V battery.

Would cost somewhere around $900.00 but you have a 200ah Lithium battery that would have the same usable capacity as a 225-250ah AGM battery, that will last longer, charge faster<--(that is important when your charging is from solar) So that is about 250% more usable ah than the Yeti 1250.
Or for $450 you just get a 12V 90ah battery which has about the same usable ah as the Yeti 1250

Then get yourself as much Solar Power as you can either afford or need which ever comes first.
This kit from Go Power is pretty good, gives you 160W of Solar Panels plus the same size 1500W pure sine inverter as the Yeti 1250 plus your regulator and I think everything you would need.
GoPower Weekender Kit 160W
So would cost about $400 more but a much better system, better battery that charges faster, and 100W more Solar charging.
As long as you do not need to burn more than 100ah of juice per day this 160W of solar should keep that battery full each day with no downtime, constant power.
Probably weigh a little bit less.
Now if you only need like say 30ah of power per day and for less than 7 days total you can just forget the Solar Panels and buy a big 200ah Lithium battery and don't worry about charging it until you get home.
Could get something like this Lithium storage system at 2.6Kwhr ( I think this works out to something like 215ah) for about $1500.
Probably last you all week.
