When the load amperage is 1.25 times of rated current for 60 seconds, 1.5 times
of rated current for 5 seconds (overload), or there is a load short circuit, the
Battery LED indicator will be flashing RED. Please refer to section 5 for
troubleshooting.

The default night length is 10 hours. The controller can learn the night length
referring to the previous night so as to adapt to the different seasons. However, it
will take some time to learn it.
Notes: When the “OFF” time set on Timer 2 is later than local sunrise
time, the controller will turn off the load output at sunrise.
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 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
