Solar connector optimization of solar photovoltaic power generation system

Update Time:2012.09.21 News Sources:sunyosolar

Under illumination, solar cell module to produce certain electromotive force, through the component parallel to form the solar battery square matrix, the matrix to achieve system voltage input voltage requirements. Through the charging and discharging controller for charging the battery, the conversion of light energy to the electric energy storage.

In dark conditions, batteries for the inverter provides input power, through an inverter to the role, will be converted into AC DC, delivered to a power distribution cabinets, distribution cabinets by switching of power supply. Battery discharge control by the controller, to ensure the normal use of the battery.

Photovoltaic power station systems should also be limited load protection and lightning protection device, in order to protect the system equipment from lightning strikes over load operation and maintenance system, the use of safety equipment. Solar energy, electric energy and chemical energy to electric energy to light energy.

Simple solar power system diagram:

From the above we can see that, left and right connection, need a large number of solar junction box, solar energy, photovoltaic connector and cable assembly. In line formation, we often use to solar connector, so that the solar photovoltaic system more convenient for management.

Below we forgive photovoltaic solar connector with three SY-BM21-A/C as an example introduced two turn solar connector:
