2. 1pcsuser manual

The controller is for off-grid solar system,especially in solar lighting system and protects the battery from being over charged by the solar module and over dischargerged by the loads.The charging process has been optimized for long battery life and improved system performance.The comrehensive self-diagnostics and electronic protection functions can prevent damaged from installation mistakes or system faults.Three battery type option:

Gel,Sealed,Flooded

Settable:

Float charging voltage;

Low voltage reconnect voltage;

Low voltage discounnect voltage;

Load start-up delay;

Optical sensitivity.

Four load working modes:

Pure lighting control

lighting control &timing control,

hand operation

debug mode.

 

Features:

12/24V automatic recognition

·High efficient Series PWM charging, increase the battery lifetime and improve the solar system performance.

·Use MOSFET as electronic switch, without any mechanical switch

·Widely used, automatically recognize day/night.

·Digital LED menu, only one key solve all setting simply

·Intelligent timer function with 1-15 hours option

·Unique dual timer function, enhance the flexibility of street light system.

·Gel, Sealed and Flooded battery type option.

·Adopt temperature compensation, correct the charging and discharging parameters automatically and improve the battery lifetime.

·Electronic protection: Overheating, over charging, over discharging,

overload, and short circuit.

·Reverse protection: any combination of solar module and battery.

Settings

. Load Control Settings

1. Dusk to Dawn

When solar module voltage goes below the point of NTTV (Night Time Threshold Voltage) at sunset, the controller will recognize the starting voltage and turn on the load after 10 minutes delay. When solar module voltage goes above point of DTTV (Day Time Threshold Voltage), the solar controller will recognize the starting voltage and turn off the load after 10 minutes delay.

2. Light ON + Timer

When solar module voltage goes below the point of NTTV (Night Time Threshold Voltage) at sunset; the solar controller will recognize the starting voltage and turn on the load after 10 minutes delay. The load will be on for several hours which users set through LED digital tube. The controller has dual timer function. Please refer to table 4-5 ―Load Work Mode Setting‖.

3. Test mode

This mode is the same as Dusk to Dawn. But there is no 10 minutes delay when controller recognizes the starting voltage. When below the starting voltage, the controller will turn on the load, if higher, it will turn off load.

The test mode makes it easy to check the system installation.

4. ON/OFF mode

This mode is to turn ON and OFF the load by manual.

A.Load Work Mode Setting

When the led digital tube is not display, Press the setting button "Key" more than 5 seconds , and keep on press it once more,led digital tube will be changed once among
