1) After the controller is installed and enters into normal operation (the battery indicator keeps steady on),
a tap on the key will turn on or off the load.
2) When the load is overloaded or short circuited, disconnect the load and make sure the load is
compatible with the controller before reconnecting it; a short circuit can be either automatically
deactivated at a set time or manually deactivated. In the manual mode, tap the load key to release the load
from the protection status and shut it off, and another tap on the load key will turn on the load again.
3) When the system is experiencing over-voltage or over-discharge, the load will be forcefully shut down.
When the system voltage recovers, the load will be released from its protection status and restored to
normal operation.
4) The load is in the manual mode by default. In either mode, long press the key to enter into the mode
setting interface in which the load mode begins to flash, tap the key to change the mode, and after setting
is finished, long press the key to save the setting and exit, or you can also wait for 10 seconds to have the
saving and exiting process automatically done.
1) Pure light control (0): when sunlight disappears and the light intensity drops to the starting point (light
control off), the controller first initiates a 1-minute delay to confirm the starting signal, and then switches
on the load for operation according to parameter settings; when sunlight emerges and the light intensity
reaches the starting point, the controller first initiates a 1-minute delay to confirm the shutting-down
signal, and then shut down the output to stop the load's operation.
2) Light control + time control (1 to 14): the starting process is the same as the sole light control, and
after operating for a preset period of time (settable from 1 to 14 hours), the load turns off automatically.
3) Manual mode (15): in this mode, the user can switch the load on or off by the key, no matter whether
it's day or night.
4) Debugging mode (16): 6V (settable) with light signals, the load is shut off; 5V (varies according to the
preset light controlled voltage and system voltage) without light signals, the load is switched on. This
mode enables fast check of the correctness of system installation during installation debugging.
5. Normal on (17): the energized load keeps outputting.
Overload and short-circuit automatic recovery time: 1st time, 5 s; 2nd time, 10 s; 3rd time, 25 s; 4th time, 30
s; 5th time, manual recovery or automatic recovery the next day.

Causes and solutions
Check whether the battery is correctly connected.
Check whether the ambient temperature is too low
and whether the display will recover when the temperature
rises.
Check whether the solar panel is correctly connected and
contact is good and reliable; check whether the solar panel
voltage falls below the battery voltage.
System over-voltage, check whether the battery voltage is
too high.
The battery is over-discharged, and will recover when
recharged adequately.
The load's power exceeds the rated value or it's short-circuited.
After removing the problem, long press the key or wait until it
recovers automatically.
Check whether wiring is sound and reliable and system voltage
is correctly recognized.
