5.7 Load output
5.7.1 Load mode settings
1) Press the “SELECT” button to switch the menus to load mode (from the main menu down to the
9th menu);
2) Press and hold “ENTER” for 2 seconds to light up the settings icon ( ), and enter the load
settings mode;
3) Press and hold “ENTER” again for 2 seconds. The settings icon ( ) blinks and the load mode
number blinks;
4) Press “SELECT” to adjust the load mode cyclically (0-17).
6. Battery Temperature Sampling
By connecting a temperature sensor to the interface ⑦, the battery’s real-time temperature can be sampled.
The temperature defaults to 25℃ when the temperature sensor is not connected. Connect a temperature sensor
and sample the battery temperature for high and low temperature protection for the battery or temperature
compensation for charge voltage of lead-acid battery (no temperature compensation for lithium battery).
7. RS485 Communication Interface
The controller has 2 isolated RS485 communication interfaces, which can be set to communication mode or
parallel mode.
7.1 Set to communication mode: perform data monitoring, parameters settings and other operations for the
controller through the port.
7.2 Set to parallel mode: allows users to use parallel cables to connect multiple controllers via their RS485
interfaces to perform parallel charge. See 5.6 for details.
7.3 Communication interfaces are defined as follows:
No.

Description
0
Only light control
(Turn on load at night,
and off in the daytime)
When there is no sunlight, the solar panel voltage is smaller than the
light control ON voltage. When the duration is longer than light control
delay that is 5 minutes by default, the load is turned on;
When there is sunlight, the solar panel voltage is greater than the light
control OFF voltage and the controller turns off the load after a 1 minute delay.
1~14 hours
Light and time control
for 1~14 hours
When there is no sunlight, the solar panel voltage is smaller than the
light control ON voltage. When the duration is longer than light control
delay that is 5 minutes by default, the load is turned on. After the
working time reaches the set value (light and time control time), the
load is turned off.
When sunlight comes out before the light and time control time is up,
the solar panel voltage is greater than the light control OFF voltage and
the controller turns off the load after a 1 minute delay.
15
Manual mode (default)
This mode allows the user to turn the load on/off with a short press on
the button (independent of day and night).
16
Commissioning mode
The mode is used for system commissioning. When there is a light signal,
the load is immediately turned off, and when there is no light signal, the
load is immediately turned on. This facilitates checking the system for right
installation during installation and commissioning.

5.7.2 Load short circuit protection settings
In some applications that are particularly prone to interference or for some inductive or capacitive loads
that may have a high current at the moment of power on, and thus may trigger the controller’s load
short circuit protection and cause the load to fail to turn on, you can choose to disable the load short
circuit protection.
1. Setting method:
1) Press the “SELECT” button to switch the menus to load mode interface;
2) Press and hold the “ENTER” button for 2 seconds to light up the settings icon ( ), and enter the
load settings mode;
3) Press the “ENTER” button to switch the menu from load mode to load short circuit protection
enable/disable interface (Scn/ScF);
4) Press and hold the “ENTER” button for 2 seconds, and Scn/ScF blinks;
5) Press the “SELECT” button to switch between “ScF and Scn”. After 5 seconds without pressing any
button, the setting will be saved automatically.
Note: ScF is to disable load short-circuit protection, Scn is to enable load short-circuit protection, and the
default is Enable.
