If the Xantrex Xpower Powerpack Solar lived up to its specifications, I would rate it 5 stars and consider it well worth the money. That's why I bought it in the first place. Unfortunately, its performance falls short of the manufacturer's claims.
The overall design of the product is very nice. I had considered building something similar based on a how-to article in Popular Science, but the Powerpack is so nicely packaged for only a couple dollars more, I chose to buy it.
The Powerpack disappoints in the amount of energy stored in its battery that is available to power other electronic devices. The battery is specified as 12 volts and 10 amp-hours. As such, I was expecting to get as much as 120 watt-hours from it, but I barely get half that.
As a test, I fully charged the battery using the included AC adapter. By "fully", I mean the unit claimed to be charged. I then ran the built-in LED lights. The manual claims they should run for 48 hours. They ran 27.5 hours for me.
I assumed this performance reflected a bad unit and exchanged it. The new unit performs similarly. Either the battery in the unit performs poorly, or the electronics to monitor and control the battery state-of-charge are weak.
As another example of the poor performance, I charged the unit completely (again based on its built-in indicator that charging is done). It indicated 100 percent charge when I turned on the AC or DC output, but as soon as I plugged in any load, it almost immediately dropped to 70 or even 60 percent. Soon after the unit's indicator dropped to 40 percent, the unit shut itself down.
So, on the one hand, this is a nice unit to carry around, and it does slowly-but-surely charge the internal battery using the included 5 watt solar panel. It does a fine job charging cell phones and iPods, and a barely acceptable job charging a notebook computer. Compared to its specifications, and for that matter my previous experience with the Xantrex Powerpack Mobile Mini, however, the product is a disappointment.

Operate your favorite gadgets anywhere with the Xantrex XPower Powerpack Solar. This portable solar device provides 400 watts of household power to run appliances and electronics. The Powerpack Solar's solar panel continuously captures, stores, and converts the sun's energy and extends the runtime of many portable devices. Two AC outlets, a DC socket, and a USB port give you plenty of options for simultaneously operating anything from laptops to cell phones to small TVs.
Portable Power for All Your ElectronicsA perfect companion for road trips, vacations, and camping, the Powerpack Solar can simultaneously run multiple devices thanks to its two 120-volt AC outlets, single 12-volt DC outlet, and USB port. The powerful built-in 400-watt inverter and sealed, spill-free 10-amp/hour AGM battery can power anything from a CD player to a 13-inch TV to a laptop to an air compressor. At the same time, the built-in USB port makes it easy to charge digital music players, cell phones, computer peripherals, and more.
A handy three-digit display helps you keep tabs on your Powerpack Solar's battery power. For those times when you want to conserve your battery, an AC charger is included for charging from a standard wall outlet, and a DC charger is included for charging from a vehicle or RV battery.
For added convenience, the Powerpack Solar runs quietly, making it a great alternative to a generator. Non-slip rubber surrounds protect the Powerpack Solar from bumps and scuffs, and two built-in lamps help you set up the unit when the lights go out or when you're getting cozy in a tent.
Clean, Green Renewable Solar PowerThe XPower Powerpack Solar is the first power pack to incorporate solar power in a compact, portable power source. It's completely self renewing, which means the five-watt solar panel captures, stores, and converts the sun's energy, replenishes the XPower Powerpack Solar's battery, and extends the runtime of many devices by up to 25 percent. An added bonus, the solar panel is detachable, so you can charge the battery and leave the panel in a safe place when you go to the beach or tackle the trail.
The XPower Powerpack Solar is covered by a six-month warranty. It measures 15.0 x 4.5 x 10.25 inches (LxWxH) and weighs 12.3 pounds.

Ensupra Grid Tie Inverter 550W - Power from Solar Panel, Wind Generator, Hydro or Storage Battery; 12.8VDC-29.3VDC to 110VAC Review

This gid-tied inverter works as advertised. I am starting with a small 100w 12v single solar module and this was the most affordable micro-inverter at an affordable price that I could find. Installation was easy, just connect the positive wire from the solar module to the positive pole of the inverter and connect the negative wire from the solar module to the negative pole of the inverter. I used grounding lugs to connect the ends of negative and positive wire to the negative and positive poles of the inverter. I crimped the ends of the wire from the DC volt meter (not voltage tester) to the inverter to measure the voltage from the solar modules.
The Ensupra Inverter checks for 12v on the DC side then samples the voltage/frequency on the grid and then synchronizes and connects to the grid. The input voltage ranges from 12v to 29v. Thus anything below 12v will shut down the inverter. Also anything above 29v will also shut down the inverter. There is a built in fan to cool the circuit when it gets hot. When you first turn on the inverter the fan comes on for about 10 seconds. Also during the day the inverter fan will cycle on and off. One thing to note is that when the fan comes on the inverter disconnects from the grid until the fan shuts off.
I can add modules until I outgrown the inverter. However, all i have to do is add a second inverter without scrapping this one. For startup this is a great grid-tied inverter.

Ensupra grid tie power inverter can obtain the solar energy from solar panel, and can tie to the grid through its output cable with no extra equipment. The installation is Do-It-Your Self (DIY).When the sun shines, the PV panel will produces DC voltage, and the grid tie inverter will change the DC voltage to AC voltage and puts out power to the home grid, saving electricity. INSTALLATION: 1, Connect the Solar Panel or Wind Turbine s DC supply cables to the DC input terminal of the inverter, be sure that the polarity is correct. Recommended DC input cable size for maximum output is 8AWG or cables that can handle more than 30A. Optimal length would be less than 8m, longer cables will experience higher voltage drop. The range of output power of Solar Panel or Wind Turbine is 50W~550W. 2, Connect the supplied AC power cord to the inverter and plug it to a home wall socket. 3, Thegreen LED indicators will glow when the grid and DC supply is detected. This indicates the inverter is operating under normal condition. The red LED will be on, the inverter will not put out power, this is called Island Protection.Please follow local regulatory electrical codes for installation. If in doubt, consult appropriate licensed contractor.Electrical Specifications: Maximum AC Output Power: 550W ACOutput Voltage Range: 90V ~ 130V AC Output Frequency Range: 46Hz ~ 65Hz Total Harmonic Distortion(THD):
