The controller must be first connect the battery, and then connect the solar panels. When the solar panels are connected in series or in parallel, paid to the highest PV input voltage of the controller. The voltage connected in parallel to the controller after the series connection cannot exceed the maximum input voltage of the controller. The total input power of the solar panel can't be greater than the rated power of the controller, otherwise, there is a risk of burning the controller.
When the cable is connected to each component, the connection should be stable and there should be no looseness. The positive and negative poles of the controller and battery should be checked clearly. Do not reverse the positive and negative poles. 100W/12V solar panel, a single solar panel connection is a 12V photovoltaic system. Multiple solar panels can be connected in parallel or in series to form 12V, 24V systems.. It needs to be used with the solar controller to protect the battery. 100W Solar Panel + 30A MTTP + 1.5M Solar Power Extension Cable.2x100W Solar Panel + 30A MTTP + 1.5M Solar Power Extension Cable + 1 to 2 Solar Panel Y Branch Cable. 3x100W Solar Panel + 60A MTTP + 1.5M Solar Power Extension Cable + 1 to 3 Solar Panel Y Branch Cable. 4x100W Solar Panel + 60A MTTP + 1.5M Solar Power Extension Cable +1 to 4 Solar Panel Y Branch Cable.
