. Load Control Settings
1. Dusk to Dawn (Light ON+Light OFF)
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; 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 (1-15h hours on)
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 for several hours which users set on the
timer. The timer setting operation is referred to as ―Load Work Mode Setting‖.
3. Test mode
It is used to test the system and 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/off the load by Setting Switch
