Advantages and disadvantages of Battery connection in series :
Advantages: Not increase the current through the output line, only increase the total output power. Which means no need to replace thicker output wires. The cost of the wire is effectively saved, the current is smaller, and the safety is higher.
Disadvantage: When two or more solar panels are connected in series, if one of them is blocked or damaged by other objects and loses its power generation capability, the entire circuit will be blocked and stop sending electricity and the whole circuit becomes an open circuit; The access range of the solar energy voltage of the controller is required to be relatively high.
Advantages and disadvantages of Battery connection in parallel:
Advantages: As long as the solar panels have the same output voltage, they can be connected in parallel to the controller for use. And if one of them is damaged, the open circuit will not affect the overall voltage, but only affect the power; The access range of the solar energy voltage of the controller is required to be relatively low
Disadvantages: Because the parallel voltage unchanged and the total current is increased, the requirements for the wire used are higher, and the cost increases; and the current is larger and the stability is slightly worse.
Overall, everyone should understands the series or parallel connection of solar panels! Of course, this is also related to the equipment used. If you want to know more, please contact us!
