Under light conditions, the solar cell module generates a certain electromotive force, and a square array of solar cells is formed through the series and parallel connection of the modules, so that the square array voltage meets the requirements of the system input voltage. Then charge the storage battery through the charge and discharge controller, and store the electrical energy converted from the light energy.

Under dark night conditions, the battery pack provides input power to the inverter. The inverter converts the DC power into AC power and sends it to the power distribution cabinet, which is powered by the switching effect of the power distribution cabinet. The discharge of the battery pack is controlled by the controller to ensure the normal use of the battery.

The photovoltaic power plant system should also have limited-load protection and lightning protection devices to protect the system equipment from overload operation and lightning strikes, and maintain the safe use of system equipment. Solar energy→electric energy→chemical energy→electric energy→light energy.

Simple solar power system diagram:

It is not difficult to see from the above picture that the connection on the left and right requires a large number of components such as solar junction boxes, solar connectors, and photovoltaic cables. In the construction of lines, we often use multi-turn to one solar connectors to make solar photovoltaic systems more convenient to manage.

Let's take the Sunyo PV SY-BM21-A/C solar connector as an example to briefly introduce the two-to-one solar connector:
