The photovoltaic module and the energy storage battery are power systems, the controller and the inverter are control protection systems, and the load is a system terminal.
The photovoltaic module is a core part in a power generation system and is used for directly converting solar radiation energy into direct current for load use or storing in an energy storage battery for standby. Generally, according to needs, a plurality of solar panels are connected according to a certain mode to form a solar cell matrix (array), and then a proper bracket and a junction box are matched to form a solar cell module.
In a solar power generation system, a charge controller is basically used for providing optimal charging current and voltage for a storage battery, rapidly, stably and efficiently charging the storage battery, reducing loss in the charging process and prolonging the service life of the storage battery as much as possible; meanwhile, the storage battery is protected, and the phenomena of overcharge and overdischarge are avoided. Advanced controllers can simultaneously record and display various important data of the system, such as charging current, voltage and the like. The main functions of the controller include: overcharge protection, reverse connection prevention, lightning protection, temperature compensation function, timing function, overcurrent protection, overheat protection, automatic voltage identification and the like. The overcharge protection is used for avoiding the damage of the storage battery due to overhigh charging voltage; the reverse connection prevention function is used for preventing the storage battery and the solar cell panel from being used or even causing accidents due to the fact that the positive electrode and the negative electrode are connected. The solar power generation system is required to be placed outdoors for use, and the lightning protection function is used for preventing the whole system from being damaged by lightning. The temperature compensation is mainly used for the place with large temperature difference, and the energy storage battery is ensured to be in the best charging effect.
