upward and downward.
Test operation
Load switch test operation is conducted on the connection solar controller to see if
the load output is normal. The test operation does not affect the working settings
under actual load, which means that the solar controller will exit from the test
mode when exiting the operational interface of the test.
Operational tips: Enter the page and input correct password; use
and buttons to

Load setting
The page of load setting could be used to set the four load working modes of the
connection solar controller (Manual, Light on/off, Light on+timer, Time control).
1. Manual control
Mode Introductions
ON Load is on all the time if battery capacity is enough and no abnormal
conditions happen.
OFF Load is OFF all the time.
2. Light ON/OFF
Light ON voltage When input voltage of solar module is lower than light ON voltage,
(Night threshold) it automatically turns ON load output if battery capacity is enough and no
abnormal conditions happen.
Light OFF voltage When input voltage of solar module is higher than light OFF voltage,
(Day threshold) it automatically turns off load output.
Delay time The confirmation time for Light signal. During the period, if light signal
voltage continues matching Light ON/OFF voltage, it will carry out
corresponding actions (The time adjustment range: 0–99mins.)

Device parameter
The software version information of solar charge controller could be checked via the
page of device parameters, and device data like device ID, device LCD backlight time
and device clock could be checked and modified. The page of device parameter in the
diagram below:
Note: the bigger the ID value of the connection device, the longer the Meter
communication identification interval (the maximum interval<6 minutes).

Device password
The password of the solar charge controller could be modified via the page of device
password; the device password is a 6-digit figure which is required before entering the
modification mode of “Control parameter”, “Load setting”, “Device parameter”, “Device
password”, “Factory reset” pages. The page of device password in the diagram below:
Note: Solar charge controller default password is”000000”

Factory reset
The default parameter values of solar charge controller could be restored via the Factory
reset page, which means the “Control parameter”, “Load setting”, “Charge mode” and
“Device password” of the devices could be restored to the factory defaults (the factory
default password of the devices is “000000”).
Failure information
The current failure information of the solar charge controller could be checked via
the Failure information page (a maximum of 15 failure messages could be displayed);
when the failures of solar charge controller are eliminated, the corresponding failure
information will also be automatically eliminated.
Meter parameter
The meter model, software and hardware version, and SN NO.could be checked via
Meter parameter page. And the three parameters (Switch pages, Backlight, Audible
alarm) could be browsed and modified as well.
Note: When the set up is accomplished, the auto switch page cannot become effective
until ten minutes later.
