VoltageThink about the voltage you will need from stand alone power systems too. You don't want there to be a lack of power due to a surge or due to variables. Instead, you need to know you can rely on a steady current no matter what you are doing. There will be times when you use far more energy at the same time than others.Look for stand alone power systems that can handle those changes. You don't want to have to limit what you do in any way. You should be able to continue your tasks and feel confident the product is going to handle your needs at any given point in time.
Find out what the set up will be for the product before you buy it. Most of them are straightforward and you shouldn't have any problems. Others though are more complex and you may need to hire a professional to help you get it all worked out.Battery LifeThe product isn't going to do much good for you with a dead battery. It is a good idea to evaluate what the battery is made from. The best stand alone power systems have lithium ion batteries so they use very little energy while giving you the best overall output. As a result, you will be able extend the overall battery life offered.The last thing you want is to hassle with a product where the battery just doesn't last very long for you at all. This can be serious problem for you and reduce the significance and value the product has for you. Don't buy a product that has poor reviews when it comes to the battery quality or battery life.Storage CapacityThe amount of storage capacity offered can vary among stand alone power systems. The reason you need to care about this is to find out how much extra power can be stored up. When you are creating more than you use, it should be stored. Then you can use it at night, on cloudy days, and when your use of power exceeds what you create that day.If you have very little storage capacity, that potential is just going to be lost. It doesn't make sense to allow such a resource to slip through our fingers like that. This can make the difference between a reduced electric bill and being completely off the grid due to the energy supply you are able to continually create.
