With the progress of society and the improvement of productivity, the demand for energy is increasing with the development of human beings. The demand for electric power is expected to increase every year. At present, China's power source mainly relies on fire and thermal power generation. Clean solar power generation has gradually prevailed in recent years. The products related to solar power generation system are also numerous and varied in quality. Take inverter and controller products as an example. Many friends who have just entered the industry do not know much about it, which leads to ambiguity in product selection.
For example, a customer asked whether it is necessary to purchase a controller when purchasing off-grid inverter. AnHui JNGE INVERTER manufacturer is popular here:
Firstly, the inverter function is simple and clear, that is, to convert 12V/24V/48V/72V direct current (storage battery, storage battery, direct current power supply) into 110V/ 220V/380V alternating current commonly used in household and the controller is used when charging the battery with photovoltaic modules, which can maintain a stable charging process, avoid the battery from being damaged by overshoot and reverse current damage to the photovoltaic modules caused by reverse current flowing out of the battery. Therefore, the full name of the controller is also called solar charging and discharging controller, which is divided into MPPT type solar control and PWM type solar controller. Everyone should pay attention to the specific use requirements and the configuration of photovoltaic modules when selecting, and select the appropriate inverter or controller.
