Product Description

Product Overview

The main characteristics of solar energy controller: the solar energy controller uses the battery discharge rate characteristics to correct the accurate discharge control. The discharge terminal voltage is a control point corrected by the discharge rate curve, eliminating the inaccuracy of the simple voltage control overdischarge, which conforms to the inherent characteristics of the battery, that is, different discharge rates have different terminal voltages. The Solar Controller has the use of single-chip microcomputer and special software, and realizes the intelligent control: overcharge, overdischarge, electronic short circuit, overload protection, unique anti-coupling protection and other automatic control. The above protection does not damage any parts and does not burn insurance. The solar controller uses a tandem PWM charging main circuit, which reduces 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 controller has an overdischarge recovery lift charge, normal direct charge, floating charge automatic control method to make the system from longer service life; At the same time, it has high precision temperature compensation.
