Product Detailed
this product is the new generation of intelligent controller of solar energy charge and discharge, it has strong stability and h

JC series of small solar power controller specification

(this manual applies to 12 V / 24 V, 10 A - 30 A controller)


Product introduction:

this product is the new generation of intelligent controller of solar energy charge and discharge, it has strong stability and high service life. This series is 12 v / 24 v automatic identification, with automatic detection battery voltage function and comprehensive protection function: overshoot, discharge, over current, short circuit, pick back, etc.

Product installation size and connection:

1.The installation environment: installed in a dry place.

2.Installation size (as below) note: fixed screw specifications M3 * 10

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 12 v system, "2" representative into 24 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 panels (positive on the left) connected correctly, electricity display began to horse race, 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 destroyed the, undervoltage, overvoltage long out). Otherwise check line.

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

Digital tube display and key SET:

When press SET digital tube display "U", namely into the street lamp and the household with select menu, and then click on the button 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, that is, the function of preserving data.

Press 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 button when into control Settings (time control time on behalf of the controller output H hours later he no longer output), each click add one hour "0 - F" represent 0 to 15 hours. (time control controlled from open lamp at the beginning of time, do not have Beijing time). Waiting for digital tube out, namely data save.

Press SET key lasts 10 seconds, digital tube display "h" representative after controlled delay h hours turn on the light. "0 - F" represent 0 to 15 hours, at this time immediately press SET key, and then adjustable delay time. Waiting for digital tube out, data save.

Press SET key for 15 seconds, digital tube display "y" for recovery factory.


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 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.


This controller has household type and street lamp type in the design of an organic whole.

This controller has 12 v, 24 v automatic identification of the design.

This controller has controlled time control (street lamp type).

This control has other controller some general protection measures.

Scientific and rigorous shape design, the use of high-grade protection means.

With the strong imitation and balanced impact, floating three-step PWM control charging ways.

Note: if the 24 v battery loss bad, voltage is less than 17 v, connected to the controller may recognition for 12 v system. (such as the discovery of battery undervoltage, controller still output normal, need to change battery).

Safety advice:

This controller has reverse connection protection, but still it is strictly prohibited to pick back, and then against load there is some damage.

Joint battery found controller doesn't work properly or doesn't work, must be timely inspection line, not allowed at the moment it is to pick up panels (panels and battery at the same time meet back and may damage the controller).

Battery has lots of energy, at any time to avoid battery accident short circuit.

Battery with will produce some combustible gas, the attention away from the spark to prevent explosion.

To comply with the battery manufacturer's safety advice, avoid contact with children, prevent accidents.
