All In One Solar Street Light Controller Waterproof For Off Grid System
Waterproof 20A all in one solar street light controller for off-grid system for lead-acid battery and lithium battery
1. New design of wireless remote-control can modify the controller parameter and read the system message according to the handheld device.
2. Digital high precision constant-current control, the maximum efficiency can reach 96%.
3. The working current can be adjusted from 0.15A to 3.3A, the regulating precision is 30mA.
4. High dynamic performances of load insure current output stability even though the battery voltage and load sudden change.
5. 3section time frame dimming function design, work time can be set range from 0h to 15 hours, power can be set range from 0% to 100%.
6. Intelligent power mode, the load power can be adjust automatically according to the battery power, can extend the maximum working time of the battery.
7. Record the system status, can record at a max 7days and monitor the whole system.
8. The true constant current but not limited the current, insure the current output stability thus decrease LED light failure, increase the LED service life.
9. Metal case, IP68 waterproof degree, can suitable use in all kinds of bad conditions.
10. With modified calculation of charging, the charging efficiency is improved, which lengthen the using time of solar energy.
11. Overheat preventing function, above a certain temperature will decrease the load or close the load.
12. Varies system protection function. Including the battery reverse connection, LED short circuit, open circuit protection and so on.
LCD display , easy to operate on LCD screen
Multi stage charging (3-stage charging , parallel charging and equalized charging function)
BTS – Battery remote temperature sensor terminal
Enable to charge Li-thium, Gel , lead-acid battery
With RS485 & USB communication port
Protection: PV array short circuit, PV reverse polarity, Battery reverse polarity, Over charging, Output short circuit
Installation and Wiring
Connection sequence: Please connect the storage battery first, then connect the load, last is the solar panel. Pay attention to the “+” and “–” in case of reverse connection.
1. TheSR-DHController is internally installed with constant current source. The max output voltage is 60V. The max amount of LED lights can be connected is 18pcs in series.
2. TheSR-DHcontroller can automatically identify of 12V and 24V system voltage. While connect to LED load, please ensure the number of LED lights in series is appropriate.
3. Before open the load, Please connect LED light first.
Please refer to the recommend as below:
Warning: if the number of LED in series is not appropriate, the controller or the LED load will be damaged.
Normally the controller is under the light + time control mode, Can use the remote control open the load and the load power will be changed according to the remote control setting during installation or need testing. The test mode will last 1min, after 1min the system will automatically recover to the normal working mode.
Load Working Mode:
Load connect to the SR-DH controller have four working timeframe, each working time and working power can be adjusted arbitrary. Different combination can realize different control mode.
A. Normal Working Mode.
B. Delay Light Time Mode:For example, setting the first time working 4hours,the first power is 0%,system will lighting 4hours later.
C. Double Time Frame Mode:For example, setting the third time working 4 hours, the third power is 0%, system will be off 4hours after work through the first and second time and then enter the fourth time continue lighting until sunrise.(Remark: this mode do not have the correct function for the night length, different season will show various lighting time in the morning.
LED Intelligent Power Control
While customer open the “Intelligent power” mode, currently the controller will enter to the intelligent power control mode, The LED load power will adjust automaticallyaccording to the battery power. The workingtime and load power preset before is still valid; system will compare with the automatically power and the preset power, and thenchoose the small one as the load output power.
For example: when the battery power is 50%,intelligent power mode calculate the load power is 60%,if now customer preset the load power is 100%,the system will choose 60% as load power. If now customer preset the load power is 20%, thesystem will choose 20% as load power.
