48V 20A solar controller-JN-T series with power display

I. Overview

The product is the new generation of intelligent solar charge and discharge controller, it has strong stability and high service life.

This series is *2 v / *4 v automatic identification, with automatic detection battery voltage function and comprehensive protection

function: overshoot, discharge, over current, short circuit, reverse polarity, etc.

II. Installation size and connection

1. Installation environment: installed in a dry ventilated place.

2.Installation size (as below) note: fixed screw specifications M3 * *0

3.Connection method (as shown in figure)

A. First joint battery (positive on the left), connected correctly, digital tube appear "1" or "2" "(" 1" representative into *2 V

system, "2" representative into *4 V system), after a few seconds, LOAD light, electricity display bright. Street lamp type LOAD

during the day long out, under voltage, over voltage LOAD long out. Otherwise check line.

B. After joint panels (positive on the left) connected correctly, electricity display began to run code, into the charging status.

Otherwise check line.

C. The last joint load (shown in bulb, positive on the left) connected correctly, lamp luminous (street lamp type long out, under-voltage, overvoltage long out). Otherwise check line.

Note: Above ABC must pick up in order, otherwise, it will damage the controller.

III.Status indication:

* TEMP: on behalf of the temperature sensor, according to different automatic temperature adjustment each point voltage.

IV. Digital tube display and key SET:

1.Press the SET digital tube display "U", namely into the street lamp and the household with select menu, and then click on the

immediately at this time there will be "1" or "2". "1" on behalf of the household type, "2" on behalf of the street lamp type.

Waiting for digital tube out, namely data save.

2.Press the SET key lasts 5 seconds, digital tube display "H" representatives control (street lamp type controller characteristic,

household type invalid), now let go and press the into time control settings (time control on behalf of the controller output

H hours later no longer output),each click add one hour "0 - F" represent 0 to *5 hours. (time control from open lamp at the beginning of time, do not have Beijing time). Waiting for digital

tube out, namely data save.

3.Press the SET key lasts *0 seconds, digital tube display "h" representative after light control delay h hours turn on the light.

"0 - F" represent 0 to *5 hours, now immediately press the SET key, and then adjustable delay time. Waiting for digital tube out,

namely data save.

4.Press the SET key lasts *5 seconds, digital tube display "y" for recovery factory.

Note:

1. h default is 0 hours (controller normal in optical when opening the lamp immediately will turn on the light, only suitable for

street lamp type) * household type is not controlled by light controller and time control *.

2. The controller has power-fail protection (namely key after regulation, the controller without electricity, also can save the last adjustment data), such as

the discovery of controller is not normal, can view "U" "H" "H" setting is normal or not.
