Installation
Attentions
 The solar panel voltage may exceed human body safety voltage when wiring 24V system. So it is better to shade the
solar panel and use insulating tools;
 Output voltage of load may exceed human body safe voltage; please connect LED before load open during
installation.
 Battery may permanent damage if short circuit, one fuse recommended between battery and controller;
 Good ventilation area recommended for heat dissipation;
 Make sure the wire length between battery and controller is as short as possible

Installation steps & connection diagram
 Firstly connect load with controller and then wire battery and solar panel to controller respectively; please pay
attention to the distinction of negative and positive; After connecting the battery, controller will automatically
recognize system voltage and display on the nixie tube. (“12” stands for 12V system, “24” stands for 24V system.)
Accepted LED load
User should make sure the LED load can meet following standards

Remark: Slow flash frequency is about 2 times/s, quick flash frequency is about 2 times/s.
Output mode
The controller can automatically detect day/night through testing the open circuit voltage of the solar panel, no
setting of a clock is required. It gets the dawn light start time through learning to daytime and nighttime in different
area or season.
There are 4 output modes available:
 Light control “on” and time control “off” (1-4.): Load starts working when controller detects night and stop
working as set time (the load stops working if controller detects “daytime” no matter the set time is achieved or
not);

Page 5/8
 Morning Mode (4~5): The load would be turned on automatically in the morning, the output power is
adjustable.
 Manual mode (6): can switch output performance manually no matter daytime or night; the power is adjustable.
 Debug mode ( ): used for debugging and installation;
Remark: if the battery is over charge or discharge, the controller will cut off the load not matter under which
mode.

Keys and settings
Skip Press: press the button within 2 seconds
Confirm Press: press the button within 2 to 4 seconds.
Configure Press: press the button over 4 seconds
Browse Mode: nixie tube tens digit is “on” (except ).
Setting mode: nixie tube unit digit is twinkling.
Configure mode: nixie tube tens digit is showing symbol “ ”
1. Under browse mode, user can “Skip Press” to view status of each output mode. When it goes to the expected output
mode(1-5), “Confirm Press” to enter setting mode, nixie tube unit digit would flash; “skip press” to chose the expected
output mode parameter; “confirm press” to confirm and exit the setting mode.
2. Under browse mode and nixie tube tens digit showing “6”, “confirm press” to enter manual output mode, nixie tube
unit digit would flash, “skip press” to chose the expected output power. When you want to exit the manual mode,
“confirm press” to enter browse mode.
3. Under browse mode and nixie tube tens digit showing (1-5), “configure press” to enter configure mode,. When you
want to exit the configure mode, “configure press” or wait for 3 minutes to enter browse mode.

Phenomenon Problem Solution
Battery indicator off Battery working problem Make sure the wiring between controller and
battery is correct.
Battery indicator slowly flash,
without output
Battery under over discharge protection Charge to recover voltage
Battery indicator quick flash,
without output Battery under overvoltage protection Cut off output for protecting load, auto working after recovering voltage
Solar indicator “off” in daytime Solar panel wiring problem Make sure the wiring between controller and
solar panel is correct.
Solar indicator “on” in
nighttime, without load output System cannot detect night
System detects “night” when solar voltage drops
less than 7V; Solar indi cator be “off” and with
load output; make sure solar panel not shone
by light if no output 3 min. later.
Solar indicator quick flash No charging
Over temperature, solar charging “off” system
auto recovered when temperature return to
normality.
