A solar charge controller or charge regulator essentially is a current and/or voltage regulator to maintain the charge in batteries. Batteries have what is called "phosphate" inside of them. This phosphate has a very significant charge potential. The crystals in the cells are made up of diodes, which are used to regulate the current. When there is too much current in a cell, it causes the crystal to become unphosphated, which causes the cell to become damaged. This damage will cause the battery to quit charging and need to be replaced.
Most "high-powered" solar charge controllers are actually single stage units. A single stage unit basically is a circuit board that has one or more charge controls. You can use a single stage controller in place of a series controller, or you can combine the two in series to regulate multiple charging stages. Single-stage must charge controllers can be run by any 12V DC source.
There are also quite a few different brand options for the solar charge controllers that you might consider. Your best bet would be to find a controller that offers everything you need and that fits your budget as well. Most people like to have the ability to lower the mppt voltage capacity if the weather is bad, but you should check the maximum input voltage capacity on the product that you are interested in to make sure that it is compatible with the electric supply you have in your area. In order to keep your solar powered equipment from running down, you should have at least a good battery backup so that your main power source does not fail. The most important thing to remember when choosing your controller is that it must meet all of your needs and make your equipment last as long as possible. Once you find the right solar panel controller for your needs, you will find it easier than ever before to enjoy your energy savings and have the time to do all of the things you enjoy!
