Product Features
1. Plug and play system with 9ft length alligator clips cable
2. Highly efficient monocrystalline panels in aluminum protective casing
3. Includes traveling case
4. Included HQST 10A controller for 12V and 24V systems
5. An upgraded 3-stage PWM charging algorithm is adopted. Application of an equalizing charging to the battery periodically or when
over discharged, can effectively prevent the battery from non-equalization and sulfating, thus extending the battery's service life.
6. With temperature compensation employed, charging parameters can be automatically adjusted.
7. A wide range of load working modes facilitate the product's application to different types of load.
8. The product provides overcharge, over-discharge, overload protection, as well as short-circuit protection.
9. By virtue of an advanced load starting method, large-capacitance loads can be started smoothly.
10.The product provides a dot matrix graphic LCD screen and a human-machine interface with a key.
11.The user-friendly design of browser and dynamic interfaces ensure convenient and intuitive operations.
12.Boasting an industrial grade design, the product can function well in various tough conditions.
13.TVS lighting protection is adopted.

2. Controller Operation Instructions
a) Step 2: Connect the battery. If the connection is correct, the controller screen lights up; otherwise, check whether the
connection is correct.
b) Step 3: Connect the solar panel. If sunlight is present and strong enough (the solar panel voltage is greater than battery
voltage), the sun icon on the LCD screen is on; otherwise, check whether the connection is correct.
c) Step 4: 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.
3.As the controller generates heat during operation, it is recommended that the controller be installed in
an environment with good ventilation conditions.
4.Choose cables with large enough capacity for connection, in case too much loss incurred on the lines
causes the controller to misjudge.
5.The controller has a common positive pole inside. If grounding is needed, ground the positive pole.
6.It's important to fully charge the battery regularly. At least once full charging every month is
recommended, and failure to do that may cause permanent damage to the battery. Only when in-flow
energy outpaces out-flow energy can the battery be charged fully. Users shall bear this in mind when
configuring the system.
7.Check whether the controller's each connection terminal is tightened securely; if not, it may suffer
damage when there is excessive current.

Browsing Menu on LCD Screen
The following menus are shown in an automatic cycle on the screen, with an interval of 3s.
Setting Menu on LCD Screen
Long press the key in any mode to enter the load mode setting interface, and the load mode begins to flash. Short press the key
to adjust the load mode, and long press the key again to save and exit mode setting or wait for 10s to let the system save and exit
automatically.
Five load Working Modes
1. Pure light control (0): When sunlight disappears and the light intensity drops to the starting point, the controller initiates a one-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 one-minute 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 to 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 key, no matter whether it's day or night.
4. Debugging mode (16): In cases of 6V with light signals, the load will be shut off. In cases of 5V (varies according to the preset light
controlled voltage and system voltage) without light signals, the load will be switched on. This mode enables fast check of the
correctness of system installation during installation and debugging.
5. Normal on (17): The energized load keeps in output state.

Manually Switching On/Off Load
When the load mode is set to 15 (manual mode), short press the key (non-setting mode) in any interface to switch on or off the
load.
Note: As load start is a type of soft start, display of the load icon on the LCD screen will be delayed after the load is switched on.
Overload and Short Circuit Recovery
Overload and short circuit automatic recovery time: 5s at the 1st time; 10s at the 2nd time; 25s at the 3rd time; 30s at the 4th time; 30s at
the 5th time, or automatic recovery the next day.

Common Problems and Solutions
Symptoms
Causes and Solutions
LCD screen does not light up.
Check whether the battery is correctly connected.
Incomplete display or no renewal on LCD screen
Check whether the ambient temperature is too low and whether
the display recovers when the temperature rises.
No charging with sunlight present
Check whether the solar panel is correctly connected, and
contact is good and reliable.
Check whether the solar panel voltage falls below the battery
voltage.
The battery icon flashes quickly, and there is no output.
System overvoltage. Check whether the battery voltage is too
high.
The battery icon flashes slowly, and there is no output.
The battery is over-discharged, and will recover after recharged
adequately.
The load icon flashes quickly, and there is no output.
The load's power exceeds the rated value or the load is short-
circuited. After the problem is solved, long press the key or wait
until it recovers automatically.
Other symptoms
Check whether wiring is sound and reliable, and system voltage
is correctly recognized.
