PRODUCT FEATURES
THPWM-30
1. Automatic system voltage identification
2. Charging program options for sealed, GEL and flooded lead-acid batteries and lithium batteries are available.
3. An upgraded 3-stage PWM charging algorithm is adopted. Application of an equalizing charge to the battery
periodically or when over discharged, can effectively prevent the battery from non-equalization and sulfuation, thus
extending the battery's service life (with the exception of GEL and lithium batteries).
4. With temperature compensation employed, charging parameters can be automatically adjusted (with the
exception of lithium batteries).
5. The product provides overcharge, over-discharge, overload protection, as well as short circuit and reverse-
connection protection.
6. A range of parameter settings and power-down saving functions are available, this requiring no repeated setting.
7. The user-friendly design of browser and dynamic interfaces ensures convenient and intuitive operations.
8. (An optional communication function) provides a RJ12 data port (output of TTL232 level or bluetooth signals),
with the data adopting the standard Modbus protocol, can be used together with our upper computer monitoring
software or mobile phone APP.
9. Boasting an industrial grade design, the product can function well in various tough conditions.
10. TVS lighting protection is adopted.

PANEL STRUCTURE
FIVE LOAD WORKING MODULES
1. Pure light control (0): When sunlight disappears and the light intensity drops to the starting point (light control
off), the controller initiates a 10-minute delay (settable) to confirm the starting signal, and then switches on the
load for operation. When sunlight emerges and the light intensity reaches the starting point, the controller initiates
a 1-minute (fixed) delay to confirm the shutting down signal, and then shuts down the output to stop the load's
operation.
2. Light control + time control (1-14): The starting process is the same as pure light control. After operating for a
preset period of time (settable from 1 to 14 hours), the load stops operation automatically.
3. Manual Mode: (15): In this mode, the user can switch the load on or off by the keys, no matter whether it's day
or night.
4. Debugging mode (16): When the solar panel voltage is higher than the "light control off" voltage, switch off the
load immediately; when the solar panel voltage is lower than the "light control on" voltage, switch on the load
immediately.
5. Normal on (17): The energized load keeps the output state.

LOAD WORKING MODE SETTINGS
In the load mode menu, press for 2s and the number (e.g. 15) will begin to flash. Press to adjust the
mode (from 0-17), and then long press again for 2s to complete and save the setting.
Note:
1. After parameter adjustment, if is not pressed and held long enough for exiting, the system exits to the
main menu after 12s, and the parameter that was set is not saved.
2. When the system is saving data, the screen may shake slightly. This is normal and the user may ignore it.
SAFETY ADVICE
CAUTION: When connected to a 24V system, the solar panel terminal voltage may exceed the limit for human
safety. If operation is to be performed, be sure to use insulation tools and keep your hands dry.
CAUTION: If the battery is reversely connected, the controller itself won't be damaged, but the load end will
have a negative voltage output, which may damage your load device. Take care not to let this happen.
CAUTION: The battery contains large amount of energy. Therefore, in no cases should the battery be short
circuited. It's recommended that a fuse be serially connected to the battery.
CAUTION: Keep the battery away from fire and sparks as the battery may produce flammable gas.
CAUTION: Keep children away from the battery and controller.
CAUTION: Follow the safety advice provided by the battery manufacturer.

BROWSING MENU ON LCD SCREEN
1). When "load mode" is displayed, long press to enter into the load mode setting. Press to adjust
the mode, and hold for 2s to save and exit; or else, the system will not save the setting that was just made
and automatically exists the setting after 12s.
BATTERY TYPES, CHARGING VOLTAGES (LITHIUM BATTERY), OVER -DISCHARGE RETURN AND OVER DISCHARGE
VOLATGE SETTINGS
In the non-load menu:
1) When is long pressed, the first interface entered is for battery type setting, and the flashing one is the
battery type currently selected. Press to select among FLD/GEL/SLD/LI.
2) After selection, short press to enter into over-discharge return and over-discharge voltage settings; or the
first to enter charging voltage settin menu for lithium battery.
3) After parameters have been set, long press for 2s to save and exit.
Parameters shall be set according to the following rule: over-discharge voltage over-discharge return voltage = under-voltage
warning floating charging voltage boost charging return = equalizing charging voltage overcharge voltage; and two adjecent
values shall have a difference of greater than 0.5V.
CHARGING AND DISCHARGING OVERLOAD PROTECTION AND RECOVERY TIME
In the charging and discharging overload protection mechanism, the relation between overload current and
protection time is as follows: An overload current 1.25 times of the rated current initiates a delay of 30s before
starting protection; similarly, 1.5 times, 5s and 2 times is 1s.
Overload recover: Automatic recovery after 1 minute.
LOAD SHORT CIRCUIT AND RECOVERY
Short-circuit automatic recovery time: 1st time, 5s; 2nd time, 10s; 3rd time, 15s; 4th time, 20s; 5th time, 4 hours
or automatic recovery the next day; or long press to make the load resume output.
Select sealed lead-acid battery
In the non-load mode menu, long press
for 2s to enter and exit the following setting menu.

INSTALLATION INSTRUCTIONS AND PRECAUTIONS
1. The controller shall be installed securely
and its dimensions are as follows:
External dimensions: 164.0 x 103.5 x 47mm
Installation dimensions: 154 x 85mm
2. Installation hole
diameter: 3.2 (mm)

PRECAUTIONS
CAUTION: If it is a 12V system, the bottom left corner of the LCD display will show '12V', '24V' system will show
24V.
CAUTION: The first step is to connect the battery. If the connection is made correctly, the controller screen will
light up; otherwise, check whether the connection is correct.
CAUTION: The second step is to connect the solar panel. If sunlight is present and strong enough (the solar
panel voltage is greater than the battery voltage), the sun icon on the LCD screen is on; otherwise, check whether
the connection is correct. (It's recommended that the operation be performed under the debugging mode).
CAUTION: The thirds step is to connect the load. Connect the load leads to the controller's load output terminal
and the current shall not exceed the controller's rated current.
CAUTION: As the controller will generate heat during operation, it's recommended that the controller be
installed in an environment with good ventilation conditions.
CAUTION: Choose cables with large enough capacity for connection, in case too much loss incurred on the
lines causes the controller to misjudge.
CAUTION: The controller has a common positive pole inside. if grounding is needed, ground the positive pole.
CAUTION: It's important to fully charge the battery regularly. At least one full charging every month is
recommended and failure to do so may cause permanent damage to the battery. Only when in-flow energy
outpaces the out-flow energy can the battery be charged fully. Users shall bear this in mind when configuring the
system.
CAUTION: Check whether the controller's connection terminals is tightened securely; if not, it may suffer
damage when large amounts of current pass through.
