Pulse width modulation (PWM) controller

PWM (Pulse-Width Modulation) solar charge controller is specifically designed for off-grid photovoltaic power generation systems. The controller can effectively control the circuit and manage the connection and disconnection of solar panels to maximize resource utilization.

Applications

PWM solar charge controller is mainly used in off-grid photovoltaic power generation systems, various solar power supply systems, DC communication base stations, small-scale solar power station systems, etc.

Features

Advanced PID algorithm allows for a more precise battery energy management system.
Three-stage charging mode maximizes the utilization of PV modules and batteries.
Full IGBT modular design ensures the stability and reliability of the controller and system performance.
Standard Modbus communication protocol based on the RS-485 communication bus (optional).
