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;

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.
