Usually there are two types of solar controllers, one is PWM and the other is MPPT.

PWM solar controller, also known as single-chip solar controller, PWM uses the digital output of the microprocessor to control the analog circuit. MPPT solar controller refers to a solar controller with the function of "Maximum Power Point Tracking". The MPPT solar controller can detect the voltage and current of the solar panel in real time, and continuously track the maximum power (P=U*I) , so that the system always charges the battery with maximum power.

Ordinary solar controller is a single-machine networking mode. When the controller is working, the photovoltaic voltage and current, the voltage and current of the battery, the voltage and current of the load and the ambient temperature, whether the battery voltage is undervoltage, and whether the photovoltaic power supply is normal, only need to check the controller on site. The data of the LCD screen only know the data.

The solar controller of the Internet of Things can allow the solar controller to automatically collect the data of the solar power supply system and upload it to the big data cloud platform. View the operation of various data in real time.
