Load Control Modes
1. Dusk to Dawn lighting mode (Mode 0) (10 min adjustable delay)
Light turns on at dusk and runs for set amount of time (see table)
3. Manual mode (15): In this mode, the load is toggled with buttons on the
controller,
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 in output state.

IMPORTANT: The charge controller ships in Lighting Control mode- if it is desired to
opertate a normal load, the load mode must be switched to Mode 17!
1) Scroll through the main menu screens with the key, stop on the load mode
screen, indicated by the light bulb in the top right corner, followed by a number in the
middle of the screen.
2) Hold the key until the number flashes.
3) Once flashing, tap the key to cycle through the load modes until the desired
selection is indicated.
4) After the desired mode is indicated, hold down the until the flashing stops.
5) The load mode has been changed.

Safty Precautions
1) When connected to a 24 V system, the solar panel terminal voltage may exceed the
limit for human safety. If operation is to be performed, be sureto use insulation tools
and keep your hands dry.
2) Check and Verify polarity of solar and battery wires before installation. Reverse
3) Installation of this controller as part of a remote solar power system is to be
4) Overcurrent protection devices (circuit breakers, in-line fuses, etc.) must be used in
appropriately sized for the conductor. Consult NEC if needed.
Wear proper PPE when installing or servicing the system.
6) Install the controller in an indoor location. Prevent exposure to elements and water.
7) Follow the safety and programming advice provided by the battery manufacturer.
LCD Screen Menu Navigation
1). Continuously press ,the screen will display the following in order: "main
menu"---"solar panel voltage"---" solar panel current"---"battery capacity"---"battery
voltage"---"discharging current"---"charging amp-hrs"---" discharging amp-hrs"---"
temperature inside controller"---" load mode"---" load mode settings"---"error code",
and then back to "main menu". If the keys are not operated for 12s, the system will
automatically return to display the "main menu".
polarity may lead to damage of components and personal injury.
5) Batteries may produce explosive gas when charging. Install the batteries in a well
performed by qualified technicians in accordance with the National Electric Code.
Use insulated tools, voltages present with solar and battery can be harmful to people!
ventilated and secure location.
8) Do not dismantle the controller. There are no user serviceable components inside.

to adjust the mode, and long press for 2s to save and exit; or else, the system
In the non-load mode menu:
1) When is long pressed, the first menu entered is for battery type selection.
the selection flashing will be the current battery type. Press to select among
FLD/GEL/SLD/LI.
2) After selection, short press to enter into LVD-Recovery and LVD set points
Or if using Lithium battery type, to enter charge voltage set points menu for
lithium battery.
3) After parameters have been set, long press for 2 s to save and exit.
Parameters shall be set according to the following rule: over-discharge voltage＜
over-discharge return voltage ≤under-voltage warning＜float charging
voltage＜boost charging return ≤equalizing charging voltage＜overcharge
voltage; and two adjacent values shall have a difference greater than 0.5 V.

Charging and Discharging Overload Protection and Recovery Time
The overload function allows for a short surge to start loads before triggering.
The controller can surge to 1.25x rated load for 30 Seconds, 1.5x for 5 seconds, or
2x for 1 second. Automatic recovery will be attempted after 1 min.

Common Problems and Solutions
Causes and Solutions
Verify connection to batteries is solid.
Temperature may be too low for LCD.
Check ALL solar wiring is correct polarity.
Check that ALL solar connections are solid.
The load will be switched on automatically
after 10 minutes (set by the user).
System overvoltage. Check whether the
battery voltage is too high.
Battery LVD. The Battery is empty.
The load's power exceeds the current rating or
it's short-circuited. After checking for faults,
long press the key or wait until it recovers
automatically.
Check whether wiring is sound and reliable, and
system voltage is correctly recognized.
