Operation
Auxiliary Load Mode
The charge controller is equipped with an auxiliary load terminal in case a user needs to connect a
light load device (For e.g., a 12V LED lamp) directly to the solar charge controller instead of the battery.
The terminals are protected by a rubber plugs to avoid improper usage and provide user safety. A
blunt tipped tweezers or a needle nose pliers can be used to eject the rubber plugs to access the
screw terminals on the charge controllers.
When the LCD shows the above icon, press the SET key for 1s, the icon
load mode.
1. Always on Mode: When the controller is set to always ON mode, no matter the charging or
discharging state, the load is always powered ON (except in when in protection state.
2. 'Street-Lamp' Function: When the load is set to Dusk to Dawn or Evening mode, the voltage and
the Day/Night delay time can be set via the Bluetooth APP, and the load can be turned on or off
by the test function during the day charging process.
2.1 Day/Night threshold voltage: The controller recognizes day and night based on the
solar array open circuit voltage. The day/night threshold voltage parameter can be modified
according to local light conditions and the solar array used.
Day/Night threshold setting range: 3.0~10.0V/6.0~20.0V (Default: 8/16V for 12/24V systems)
2.2 Day/Night delay time: In the evening, when the solar array open circuit voltage reaches
the setting day/night detect voltage, user can adjust the day/night delay time to make the
load turn on a little bit later.
Day/Night delay time setting range: 0~30min (Default: 0min)
2.3 Test Function: When the controller is working in Dusk to Dawn or Evening mode, press the
SET key for 3s to turn on the load. Press the SET key again or the load turns off automatically after
1 minute. If the controller is operating in always on mode, the test function does not work.
3. User-defined Mode: If the load mode is selected "USE", then you can switch on and off the load
output manually by pressing SET shortly.
The default switching state of the load in manual mode can be changed by Bluetooth APP. At the
same time, the output to the load can be turned on or off.
● If the controller turns off the load due to low voltage protection, overcurrent
Protection, short-circuit protection or over temperature protection, the load will
turn on automatically when the controller recovers from protection state.
● Please note: Pushing the SET button can still activate the function of the key,
even during of the above four kinds of protection states.
