One thing to consider with some batteries, is venting. To prevent hydrogen built-up. (It can explode).
It's a super light gas, so having the top of the Job-box open should work.

Before you can 'size' a system, you need to define the loads. How much power are you going to need?
Do you want your PV power output to be high enough to charge the battery bank, while at the same time, be able to take care of your day-time load?

I could not find any reviews on that 200W folding array. I did see a review of their 100w folder, that questioned the power out spec.

I own some good 200W panels, and they only able to put out the full 200W on the very best days.. Like when it's very cool (or freezing cold) and very sunny.

In my opinion, if you need a full 200 watts of PV power, you might want to buy 250 to 300 watts of PV.. Conditions vary. Sometimes it's hazy or partly overcast etc..

One other question.. Is this system going to stay at home? Stored in garage?
Or does it need to be portable enough that you can take it camping?
