My 2 cents... A battery charger is definitely a good idea, that way you can keep the battery topped off when an outlet is available. I would consider a marine charger permanently mounted in the engine bay. I would also recommend a battery management system such as the one sold by Equipt/National Luna, if I were in the U.S. I would get it to replace my current manual set-up.
Furthermore I would say that if you are looking to keep your house battery topped off and part of your equipment includes a 12v fridge: forget about the 13.5. We have an 80 watt panel and in some conditions it is not enough, I would encourage you to spend the money on a decent 60 to 90 watt panel and charge controller.
Lostworlexpedition makes a really good point about the National Luna dual battery system being the way to go. The permanent mount marine charger is also a fantastic idea!
The Nomad 13.5 is really designed for mid-duty electronic usage. Coupled with the Sherpa 50 and the Sherpa UI you are looking at a power system that would be great for running a laptop for a couple (1-2) hours between charges (100 watt output with the UI). The Sherpa 50 is a 50 watt-hour unit. It charges off the Nomad 13.5 in 6 or so hours. Think small to mid-sized portable electronics. Cell phone, sat phone, iPod, iPad, small laptop, etc.
Catusjk the way that the system is supposed to work is as follows:
The LED will be solid green if the battery pack is full and in the off position.
Let me know if you see something different.
Also, you can charge it with any AC mini USB if it is pushing out the normal 5 volts.
I think I am going to pull the trigger on a Nomad 13.5 and Sherpa 50. I'd love to size it up for peace of mind, but budget is a consideration. ~$340 for the smaller one vs ~$600 for the larger Nomad/Sherpa set up. I'd love to see some more real life reviews, they are few and far between but always very positive.
This is the first season I'll be taking a laptop out for field work (heaven help me). I haven't in the past due to not wanting to deal with keeping it charged or needing to keep track of it. I have very limited access to the electric grid for a typical 2 month season and often without reliable vehicle access. I should be able to charge a macbook air enough to get a 2-3 hours or more of work per day with the Sherpa 50. I should be able to do this with a DC-DC charger as I get about 3 hours out of the internal 37W-hr battery.
There is just this niggling nagging in the back of my mind that bigger is better.

Just a little side note here... I have the Goal Zero Guide 10 AA charging pack, and the clamshell charging pack melted to the point of being unuseable. All of this happened why it was being charged...with the sun. (I have two emails and three phone calls into the company so far.)
