High Efficiency MPPT Solar Charge Controller

Product Description
High efficiency MPPT solar charge controller
1. Function introduction

The solar controller in solar photovoltaic system, solar panel, battery, coordination of work load, is a very important component in photovoltaic system. The whole solar photovoltaic system is efficient, safe operation.

Solar energy is mainly used for system family, commercial areas, factories, traffic, communication, and pastoral areas to solar power supply. The solar street lamp controller has the following basic functions:

And overload protection

And short circuit protection

And reverse discharging protection

And reverse polarity protection

And lightning protection

And under voltage protection

And overcharge protection

2. Characteristics

(1) 12/24V automatic identification

(2) efficient tandem PWM charging, extend battery life, improves the system performance.

(3) using the power of MOSFET as an electronic switch, without any mechanical switch

(4) LED digital function menu settings and display concise, easy to use

(5) seal, colloid, open type three kinds of lead acid battery charging program optional

(6) using the temperature compensation, automatic adjustment of the parameters of charge and discharge, improve the service life of the battery

(7) controller with over temperature, over charge, over discharge, overload, short circuit and automatic protection function

(8) any combination of light battery and battery reverse automatic protection function

3 product selection

A: Should choose the low power consumption of the controller, the controller 24 hours of uninterrupted work, such as high power consumption, will consume part of the electric power, the best choice of power consumption in the controller 1 Ma the following.

Two: To choose a charge controller and high efficiency, the maximum current controller can automatically track panels, especially in winter or insufficient light period, high efficiency of about 20% of the other.

4 control principle

The battery voltage acquisition: For the identification of the battery working voltage. Using the micro controller of PWM function, charging the battery.

The battery open circuit protection: If the battery open circuit, if the normal charge in the solar cell, the controller will be off the load, to ensure that the load is damaged, if at night or in the solar battery is not charging, controller because of their own do not have access to electricity, there won't be any action.

The overcharge protection: Charging voltage higher than the voltage protection, automatic shutdown to charge the battery; Then when the voltage falls to the maintenance of the battery voltage, floating charge, float charge voltage when below the maintenance after closing, enter the charging state. When the battery voltage is lower than the protection of voltage, load switch controller automatically shut down to protect the battery from damage. Through the PWM charging circuit (intelligent three stage charging), can make the solar panels to maximize the effectiveness of the system, improve the charging efficiency. The product supports battery reverse, over charge, over discharge.

5 wiring method
Methods: The solar street lamp controller general should first connected load, followed by the battery line, and finally connected with a solar panel line.
