Function
When the load is set to Dusk to Dawn or Evening mode, the
voltage and the
Day/Night
delay t
can be set b the mobile phone APP, RS485 or
Wechat APP
, and the load can be
turned on or off by the test function during the day charging process.
2.1
Day/Night threshold
voltage
The controller recognizes day and night based on the solar array open circuit voltage.
This day/night threshold
voltage
can be modified according to local light conditions and the solar array
used.
Day/Night threshold
setting range: 3.0~20.0V(Lithium, default: 8.0V)
Day/Night threshold
setting range: 3.0~10/6.0~20V(Liquid/Gel/AGM,Default: 8/16V)
2.2 Day/Night delay time
In the evening, when the solar array open circuit voltage reaches the setting day/night
detect voltage
, you
can adjust the day/night delay time to make the load turn on a little bit later.
Day

Night delay time setting range: 0~30min(Default
:

Test Function
When the controller is working in
Dusk to Dawn or Evening
mode, press the

key again or the load turns off automatically after 1 minute.
If the controller is operating in

Faults
Reason
Troubleshooting
Battery voltage is too low
Reduce the load, the controller will resume work
after 1minute.
After the temperature decreases, the controller will
work normally.
Battery voltage is too high
Short Circuit
Over Current
Over temperature
Switch off all loads, remove short circuit, load will be
reconnected after 1 minute automatically
Charge or discharge the battery so that the battery
voltage is within the normal operating range(8.5~15.5V
or 20~30V).
Check if other sources overcharge the battery or battery
parameter is set correctly. If not, controller is damaged.
Load will be reconnected when battery is recharged.
