Problems solved by technology

[0008] The DSP control system used in traditional solar photovoltaic smart chargers is an integral point type, and users have to spend a lot of time and energy on writing control algorithms to handle decimal operations, and there is no high-precision PWM output channel

[0009] The solar photovoltaic smart chargers in the current market use a single microprocessor and do not have a good human-computer interaction interface. They cannot well reflect the internal parameters and working conditions of the solar smart charger, and cannot allow users to have a good intuitive and comprehensive understanding. Whether the solar photovoltaic intelligent charging system meets the requirements, and the user's simple operation and control system cannot meet the user's needs
