Commissioning
Positioning
⚫ Position the solar panel in a location with the strongest possible strong and long-
lasting solar radiation.
⚫ Align the panel so that it is exposed to direct sunlight for the longest possible time.
Usually, depending on local conditions, a higher position with an orientation to the
south is suitable for this.
Use
⚫ Using a charge controller, connect the solar panel to a power storage device, such
as a DC12V battery, or to a load.
NOTE:
The charge controller controls the current flow and charging process and prevents
current backflow from the battery to the solar panel. From the battery to the solar
panel. In addition, on cloudy days, only a fraction of the nominal rated power is
achieved.
CAUTION!
If you use the solar panel on or in the car or in the car, do not use it in traffic!

Charge controller
Recommendations for Safe Use
1. The controller is a 12V controller. When installing it for the first time, make sure the
battery has enough voltage so that the controller can recognize it as the correct type
of battery.
2. Install the controller as close to the battery as possible to avoid voltage drop caused
by too long wire, which may affect the normal determination of voltage.
3. The controller is suitable for DC12V lead-acid batteries, ternary lithium batteries
and lithium iron phosphate batteries. Select the appropriate battery type in the menu.
4. The controller can only use PV panel as a charge source. Do not use DC power
supply as a charge source.
5. The controller will generate heat when running. Install the controller on a flat, well-
ventilated surface.
System Wiring
1. Connect the anode (+) and cathode (-) of the battery to the controller according to
the diagram and take care to avoid reverse connection.
2. Connect the anode (+) and cathode (-) of the load to the controller according to the
diagram and take care to avoid reverse connection.
3. Connect the solar panel to the controller according to the diagram and take care to
avoid reverse connection.

Boost charge voltage - regulation interface
(only valid for b04, b07)
When the battery voltage rises to this set voltage, PWM
charging is enabled.
During normal charging, the arrow indicator is always on, and
after entering float charging, the arrow indicator is slowly
flashing.
Setting recommendation: It is recommended to keep the
default value.
Setting method: same as above.
Over discharge recovery voltage - regulation interface
(LVR)
When the controller turns off the load due to low voltage, the
load will not be turned on until the battery voltage rises to the
set voltage again.
Setting recommendation: It is recommended to keep the
default value.
Setting method: same as above.

11
Model: TX-214,TX-215; Article No. 5023,5024; 10/2022
Over discharge voltage - regulation interface (LVD)
The controller will automatically cut off the load output when
the battery voltage drops below this voltage.
Setting recommendation: It is recommended to keep the
default value.
Setting method: same as above.
Light control ON/OFF threshold (PV panel voltage)
In light control or time control mode, when the controller
detects that the voltage of the PV panel is less than this set
value, it will turn on the load after a delay and otherwise turn
off the load. At night, if the ambient light around the solar panel
is too bright, the solar panel output voltage will become higher,
which will cause the controller to automatically turn off the
load. At this point, it can be adjusted somewhat by this value.
Setting recommendation: It is recommended to keep the
default value.
Setting method: same as above.
Light control ON/OFF delay threshold (in seconds)
When the controller detects that the PV panel voltage is lower
than the set threshold, it will delay to turn on the load. Such
time value can be used to prevent turning off the lamp due to
erroneous judgment caused by the interference of car lights or
lightning at night.
Setting recommendation: It is recommended to keep the
default value.
Setting method: same as above.
Short-circuit protection setting
Some inductive or capacitive loads may draw a large current
at the moment of start-up, which may trigger the short circuit
protection of the controller and cause the output to shut down.
In this case, the user can turn off the short-circuit protection.
SC.F is Off, SC.n is On, and the default is On.
Setting method: same as above.
PWM charge settings (only valid for b04, b07)
PWM is likely to cause the system to produce noise and
interference. Especially when a lithium battery with BMS is
used, PWM charging may trigger BMS protection and cause
system failure. Therefore, the customer has the option to turn
PWM off. In this mode, once the battery is charged to the
preset voltage (interface 7), the controller will stop charging
immediately, and restart charging after the battery voltage
returns. PoF is Off, Pon is On, and the default is On.
Setting recommendation: It is recommended to keep the
default value.
Setting method: same as above.

Load light control mode settings
Lc1 indicates that the load is working at night, Lc2 indicates
that the load is working during the day, and the light control
has priority over the time control to turn off the load. Lc3
indicates that the load is working at night, Lc4 indicates that
the load is working during the day, and the time control has
priority over the light control to turn off the load. Example: If it
is set to 16H, since the night/day length is only 12 hours, Lc1/2
will run for 12 hours only, and Lc3/4 will run for 16 hours.
The default is Lc1.
Setting method: same as above.

FAQ
Q1: Why isn’t charging displayed after my PV panel is connected?
A1: Check if the PV panel wiring is correct, and if the connection is reversed or
false; check if the PV panel voltage is too high; check if the PV panel is blocked and
the voltage drops consequently.
Q2: Why is the charge current so small?
A2: The higher the PV panel power, and the stronger the sunlight, the larger the
charge current, and conversely, incorrect PV panel voltage, and blocking by foreign
object, shadow, etc. will cause the current to decrease. In addition, when the battery
voltage is high, it will enter a floating charge state, at which point the charge current
will also become smaller and smaller.
Q3: Why won't my load light up?
A3: The causes that the load is not turned on may include, the load operating mode
is not set correctly. For example, the light control is set up but the load is not turned
on during the day. In this case, battery is low, resulting in the controller to cut off the
load, or the load is not properly connected, disconnected, burned out or the like.
Q4: What if I don’t need to use electricity for an appropriately long period of time?
A4: If the daily power generation of the PV panels is less than the amount of
electricity used by the load, it will result in a situation where the generation does not
cover the consumption. In this case, it is recommended to increase the number of
PV panels. In addition, you can increase the battery capacity, as well as reduce the
wattage of the load or working hours to balance the whole system.
Q5: Why does a fully charged battery run out of power after a short use?
A5: The battery is close to the end of life. You can do a simple test. For example,
after discharge, charge the battery by PV panel or mains. The voltage will rise very
soon. Then, stop charging and turn on the load. The voltage drops very soon. This
indicates that the battery performance has degraded. You should replace a battery.
