. 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.
