Solar batteries come in various voltages and capacities which enable them to be connected together for the storage power required in a specific system. This is an efficient and common practice in fitting the system to the application.
There are batteries that are too heavy or too bulky for your site. By connecting smaller batteries in Series or Parallel the same power requirements are met with no loss of impedance.
Paralleling batteries is a configuration of smaller batteries wired together. Battery terminals of like polarity are wired together; all positive terminals are wired together and all negative terminals are wired together, and the last battery is wired to common buss bars.
Paralleling configurations provide higher capacity while voltage remains the same.
Series connection is a configuration of smaller batteries wired together by connecting the positive terminal to the next battery’s negative terminal. Concorde suggests beginning the connection with the first positive terminal of the series. At the beginning of this series of batteries, connect the positive terminal to the common buss bar positive and the last battery’s negative terminal to the negative buss bar or ground.
Series configuration provide higher voltage while capacity stays the same.
