China Solar Charge Controller Product Introduction PWM solar charge controller adopts innovative design, is easy to install, and is very user-friendly. It has optimized charge and discharge management, greatly extending the service life of the battery. At the same time, it can display parameters explicitly. All parameter values can be set to meet various applications. The battery also has 4-stage PWM charging modes, including bulk, absorption, floating and equalization modes, suitable for sealed, gel, floodlight and other customized battery types. Features The聽PWM聽solar charge controller can automatically detect the battery voltage or maintain a fixed voltage, and is equipped with LCD to display photovoltaic data and chart to simulate the power generation process. All its working parameters can be reset, saved and transmitted to the computer or other terminal devices. In addition to conventional input, output and battery protection, this battery also provides solar panel overcurrent protection.
