Product Description

Product Overview

Main Features of Solar Controller: Solar controller uses battery discharge rate characteristics to correct accurate discharge control. The discharge end voltage is a control point corrected by the discharge rate curve, eliminating the inaccuracy of the simple voltage control over the discharge, which conforms to the inherent characteristics of the battery, that is, different discharge rates have different end voltage. Solar controller adopts microcontroller and special software to realize intelligent control: overcharge, overdischarge, electronic short circuit, overload protection, unique anti-coupling protection and other automatic control. The above protection will not damage any parts, nor will the combustion insurance. The solar controller uses a series PWM charging main circuit, which can reduce the voltage loss of the charging circuit by nearly half compared to the diode charging circuit, and the charging efficiency is 3 % -6 % higher than that of non-PWM, increasing the power consumption time. The solar energy controller has the method of overdischarge restoring lift charging, normal direct charging, floating charging automatic control, so that the system service life is longer; At the same time, it has high precision temperature compensation.
