Setting:hold left key until number flash,click【+/-】to adjust,and
hold left key again until number stop flashing ,the setting is
saved.

Load output timer control
【24H】-output turn on all the time.
【0H】-output turn on only during Dusk to Dawn(D2D).
【1~23H】-output turn on after sunset and turn off after
1~23H. Attn：no matter which is selected ,output will turn off
when battery is in a LVD condition.
Setting method:same as above one.
NO.4
controller’s body temperature display.if the controller gets
too hot during running ,it will automatic shut down and wait
for the temperature to drop to normal level ,and then it will
work again.
NO.5
Charging ampere display.(only for some model)
NO.6
Discharging ampere display.(only for some model)
NO.7
Charge voltage setting（only for B01,B02,B03）
Different battery types have different maximum charging
voltage. Consult your battery supplier for more
information.Default setting is recommended.The setting is the
same as above.
NO.8
Low voltage re-connect（LVR) setting
When a low voltage disconnect happens,the controller will
wait until the voltage raise more then this voltage,then it will
re-connect the load again.
Default setting is recommended.The setting is the same as
above.
NO.9
Low voltage disconnect (LVD)setting.
When battery voltage is lower than this voltage,the controller
will cut off the output automatically .Default setting is
recommended.The setting is the same as above.
NO.10
D2D trigger value(solar panel voltage)
When the work mode is D2D or Timer,the controller will
detect the solar panel voltage to decide whether its day or
night,so to decide to enable load output or not.the higher this
value is,the earlier it enables the load output.
Default setting is recommended.The setting is the same as
above.
NO.11
D2D trigger delay value(Second)
When the controller detect the solar panel voltage is lower
than trigger value,it will delay for 10S and detect again to
make sure night falls, then enable the load output.some car
light or thunder lighting will confuse the controller and make it
think its daytime,using this delay can prevent interference.
Default setting is recommended.The setting is the same as
above.
NO.12
Short-circuit protection setting.(only for some model)
Some inductive or capacitive consumer will trigger the
short-circuit protection during start up.therefore,you can
disable the SC-protection manually.
SC.F=OFF, SC.n=ON.the default is ON.
Default setting is recommended.The setting is the same as
above.
NO.13
PWM charging enable(only for B01,B02,B03)
PWM could generate noise and interference which will trigger
a high voltage protection in a Li-Battery BMS
system.Therefore,to avoid this happen,you can choose to
disable the PWM charging.The controller will charge the
battery until Setting voltage(Menu NO.3),then it will fully stop
charging,when battery voltage drop ,it will re-charge again.
P.oN=PWM ON. P.oF=PWM OFF.
Default setting is P.oN. The setting is the same as above.
NO.14
Output mode control.
Normally a LED light connected to the output terminal will
work only after sunset,therefore,LC1 can be selected.But some
load equipment requires to work only after sunrise,for
example,a camera or a pump.therefore ,you can choose LC2.
LC1 and LC2 are logically opposite on D2D control.
If you have set a timer(1-23H)control,for example 16H,but in
reality the night /day is only 12Hour.LC1/2 means output work
only 12H(any sunset or sunrise will stop the countdown) ,but
LC3/LC4 will work 16H(ignore any sunset or sunrise and
countdown until setting hours)
Default setting is LC1. The setting is the same as above.

when PV voltage exceed 50V and automatic recover when
voltage drop below 45V.(for 12V/24V system)
FAQ
Q:why the controller is not showing charging when I connect the solar panel?
A:please carefully check the solar panel wires are connected correctly,and there
is no reverse.the PV voltage should be higher than the voltage of the battery,any
sewage or shadow on the PV will cause the voltage drop.please use a 18v PV to
charge a 12V battery under normal circumstances.
Q:why is my charging current very small?
A:use more solar panel and stronger sun light will increase the charging
current,otherwise,using the wrong PV voltage or sewage and shadow on the PV
will reduce the charging current.in addition,when the battery voltage is high it
will enter float charging mode,also the charging current will become smaller.
Q:why my consumer is off?
It could be wrong working mode,like setting the work mode to D2D,but you are
asking why my consumer is off during the daytime.or battery is not enough and
a low-voltage disconnect has happened.or your consumer is broken,to check
that ,you can directly connect your consumer to the battery to see if it is
working,please carefully check the wires and so.
Q:the solar power stored is not enough to supply the consumer
A:If the power generated by the solar panel is less than the consumer used,the
consumer will have to get the power from the battery storage.and day by day,it
will cause a LVD finally at some moment.please use more solar panel and add
more battery capacity to prevent cloudy or rainy day,or you can reduce the watt
of the consumer or working time to balance the system.
Q:why my battery runs out of power very quickly after it is fully charged?
A:your battery could have been used for a very long time,and after few hundred
of cycling, its dying.a dying battery will not have the capacity to keep the
electricity.run a simple test like this,when your charge your battery ,the voltage
raise very quickly ,and when you discharge it again,it drops very quickly,this
means you should change your battery.
