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. 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 setting button.
