3.Product feature and application of PWM  controller for solar system 

12/24 automatic recognition.

High efficient series PWM charging, increase the battery lifetime and improve the solar system performance.

Use MOSFET as electronic switch, without any mechanical switch.

Gel and lead acid sealed battery type optional.

As a key component of photovoltaic power generation system, the short life of battery is one of the main reasons that impede the performance and promotion of the whole PV system. According to the working principle of the battery and the actual application, the main factors that affect the life of the lead-acid battery in the photovoltaic power generation system include the setting of the charging voltage, the setting of the control point of the over and discharge, the temperature and the operating environment. Based on these factors, the limitations of common battery charging and discharging methods are analyzed, and the charging and discharging modes are improved.
