There are many reasons why a person would need a complete solar panel battery charging solution. One is for people who are on expeditions, or extended camping outings, where you are gone for weeks at a time. You will probably still need to do some kind of online work, keep connected to friends and family and certainly need to keep yourself entertained for that long. You may also need to communicate with the outside world in case of an emergency.
Another reason to have a complete solar panel battery solution is for those who like to travel and stay in their recreational vehicles. A good RV person knows that the best spots don't have any hook ups to electricity, and are in places that running a generator is just impractical, as well as noisy. In this case, operating solely off of batteries is the only way to go.
In the first case, there are many different solutions, but the best one are the types of chargers that are meant for such conditions. While they have many different kits to choose from, one of them stands out for powering all of your base camp needs, and much more.
Here is all that you get in the Extreme Base Camp Kit. You get two of their top o f the line 350 batteries. Each of these provides 350 watt hours of power storage. They are treated to be UV and weather resistant. They have status monitors, replaceable fuses, and a built in temperature control monitor to make sure the operate safely as well as for the long term.
This kit includes four Boulder 30M solar panels, each with 30watts of power, equaling a full 120 watts of solar power. These are highly efficient mono-crystalline panels, using the latest in solar technology. You also get the universal inverter, or UI which has a multiple plug-in for American and European plugs, and provides 400 watts continuous, and 800 watts of peak power for any electric device.
You also get 4 Light-a-Life Led light systems, each with a 3 Watt high intensity LED bulbs. These are rated for more that 20,000 hours of use, and are equivalent to a 45 watt incandescent light. They can be powered from any DC power source, it also has an off/on switch, and even a carabiner on a nine foot cord, so you can hang them any where. You get the wall charging unit, connector cables for the two power packs, cigarette adapter, and four of the carabiner cords, and you get all of this for just ,219.95.
You can buy extra power packs, more solar panels, and even smaller Sherpa systems if you need them. You can combine different single purchases with your combo kits for added power if you need to, piggy backing up to three power packs at one time. The Sherpa kits even have panels that fold up into their own carrying cases.
For the second type of battery solution, you need to think about what your needs are first. If you are thinking about complete RV solar solutions, then you need to get at least a sixty watt solar panel, just to start. You are going to have to get some high output deep cycle marine batteries, at least one for basic needs, if you plan to run things like a microwave oven, or media equipment, then two is recommended. For the best systems, you should at least 120 full watts of solar panels, with 2-4 hundred watt systems optimal. This means you will be able to not only charge up your batteries for night time use, but also all of your appliance needs on top of this.
