This review is for the Goal Zero Sherpa 120 Explorer Kit New Goal 0 ELITE Sherpa 120 Explorer Kit Delivers Power To Charge AC And Handheld Devices Portable, which includes the Sherpa 120 battery Goal0 11102 Sherpa 120 Battery the Nomad 27 solar panels Goal0 12201 Nomad 27M Solar Panel, and the Sherpa Universal Inverter Goal0 13002 Sherpa Universal Inverter.I bought this system to use on an extended backwoods trip to run a CPAP machine while I sleep. Since this would be running a medical device, I felt it was important to know I could trust the system.I carefully measured (using a Kill-a-Watt) P3 International P4400 Kill A Watt Electricity Usage Monitor the power my CPAP was consuming and knew that in good conditions the battery alone should last nearly 3 nights, so the solar panels wouldn't need to fully charge the system in a single day. I have also measured the CPAP using (using a Watts-Up) "Watt's Up" RC Watt Meter & Power Analyzer WU100 Version 2 --- SALE! when running directly from 12v and it consumes about 30 watts a night (vs 37watts a night on 120v).In field testing and subsequent follow up this is how I would rate the system and some important suggestions for using it to maximize your results.The battery holds as much power as advertised, I've measured it several times and it continues to perform well. The solar panels likewise perform as expected and charge the battery well. When solar charging the battery it takes longer than it does to charge it from Grid power. To get the most from your soloar panels, you'll need to adjust the panels to face the sun 2-3 times in a day. This was especially important for me when we were in a forest and the sun moving through the day changes where you need to be to get them in the sunlight. I was able to nearly fully charge the system in a full day of Arizona sun using the solar panels.The system connects and works well. The only plug that seems slightly loose is the output plug on the battery. The other connectors are nice and sufficient. The output one should snap to give you extra security that your device will remain powered. The cables on the solar setup are nice and give you length to move things around. If a wind is possible where you set it up, use a stake through the grommet holes to keep the solar panels from blowing over.Clearly the weak link in the system is the inverter. The Inverter is inefficient on smaller loads. My CPAP averages only ~5 watts to run at night but consumed nearly 8 watts of power through the inverter. This really consumed my battery capacity. I was shocked to measure and realize that 30% of my consumed power was due to inverter inefficiencies. By running the CPAP directly from 12v, I was able to not only remove the inverter load, but also eliminate the need of the unit to transform from 120v to 12v, providing additional savings. Running the CPAP through the inverter at 120v, it won't quite make 2 nights without a small bump. Running the CPAP directly at 12v, I am able to squeak out 4 nights from a single charge. Of course this will all depend on your CPAP and pressure settings; I use a lower pressure of 6 and an efficient Resmed Elite system.The system is nicely rugged and in my case even blew over and down some rocks with no damage. I bought the available silicone sleeve for the battery which is a nice way to protect your investment.Focus on using 12v loads directly and make sure you are running your necessary equipment as efficiently as possible to maximize your run times. Hopefully Goal Zero can tweak the inverter to improve its performance since it's the weak link in an otherwise impressive system.One thing to note, if you leave the battery unattended for a long time (a few weeks) it goes into a deep sleep even shutting down the display (to conserve power). When you turn it back on it'll appear discharged but it really is holding the charge well. If you plug it into the solar or wall charger for a bit (~20 min) it'll snap back and realize that it's actually fully charged. It appears that after a deep sleep it takes time to realize it's fully charged.

Some of my major gripes:1. Battery unit doesn't hold a charge. I charge the unit with the Ac adaptor to a full charge. a week later and the battery level indicator is on 1/10 bars. ie dead. I bought this kit hoping to have stored power for future power outages and don't expect miracles (don't expect unit to hold a charge for 6 months w/o a re-charge) but cmon.2. When Solar panel is connected to battery to charge battery, when the sun is out, the panel charges the battery. When its cloudy or at night, the panel seems to drain the battery. Again, if there's a power failure, I'd want this kit to always be hooked up and have the solar panel always charging the battery and if its cloudy and I;m away I don't feel I should babysit this unit and unplug the panel.3. On full charge, battery seems to fully charge an iPhone 2-3 times. That's it. Now that's amazing if you really need a charge. But for $500 I'd want a little more juice.On a positive note, I feel these units are designed well, look great, feel good in the hands, have great input and output ports... nicely labeled... etc etc. But perhaps this technology isn't quite there yet. I feel I spent a a LOT of money to do what a $34.99 Incipio battery can do.Sorry.

This set up really comes in handy. Use it for lighting to recharging my cordless power tools. Works great for camping. Would buy it again in a heart beat.
