Durable 40A PWM Solar Charge Controller Off Grid With LCD Display
40A LCD display Off grid PWM solar charge controller
What is the principle of pwm solar charge controller?
The solar controller adopts high-speed CPU microprocessor and high-precision AID analog-to-digital converter. It is a microcomputer data acquisition and monitoring control system. Not only can the current working status of the photovoltaic system be quickly collected in real time, the availability at any time and the reliability of the quality of the inspection system components provide an accurate and sufficient basis. In addition, the solar controller also has the function of serial communication data transmission, which can perform centralized management and remote control of multiple photovoltaic system substations.
