Product Usage Instructions

Step 1: Wiring Your Solar Controller

1. Turn the adjusting screw counterclockwise to move the plate inside terminal downward.
2. Peel off the cable tip coating by about 8 to 10 mm.
3. Insert the wire into the opening between the plate and the top of the terminal hole.
4. Turn the adjuster clockwise to crush the wire in the terminal hole
5. Ensure all connections to and from the solar controller are tight.

Step 2: Connecting the Solar Panel

Frequently Asked Questions (FAQ)

1. What should I do if my battery voltage is lower than the solar panel voltage?
   If your battery voltage is lower than the solar panel voltage, it cannot be charged. Ensure that the solar panel voltage is higher than the battery voltage for proper charging.

2. How do I set the charging cut-off voltage for different types of batteries?
   After connecting the battery, the controller will automatically detect a 12V/24V DC system voltage. If you are using a different type of battery, you need to manually set the charging cut-off voltage.

BL912 Installation and Setup Tutorial

How to use Y &H BL912 series?

Step 1: The battery must be connected first.

HOW TO WIRE YOUR SOLAR CONTROLLER?

1. (Controller terminal side)Turn the adjusting screw counterclockwise until the plate inside terminal moves downward.
2. (wire)Please peel off the coating of the cable tip by about 8 to 10 mm
3. Insert the wire into the new opening between the plate and the “top” of the terminal hole.
4. When turning the adjuster clockwise, the plate moves upward and crushes the wire in the hole of the terminal.
5.  Make sure all connections going into and from the solar controller are tight.
   • Note： This solar controller charging is from high voltage to low voltage, please make sure solar panel voltage is higher than battery voltage, otherwise it cannot be charged.

Step 2:Connect the solar panel

Solar panel voltage selection:

**For safety reasons, connect solar panels and batteries within the recommended range.

Tip: After connecting the battery, the controller will automatically detect 12V/24V DC system voltage, the system defaults to lead-acid battery, if it is other types of batteries, you need to set the charging cut-off voltage.
When Wiring, Please

1. Make sure your battery must be atleast 60% charged prior to connecting to solar controller.
2. Always connect and turn on your battery first! Wire your PV after LCD screen power on.
3.  Never connect your PV array to the solar controller when LCD OFF.
4.  Careful your input power and voltage does not exceed the solar controller’s max value.
5.  Always connect battery first, then solar panel.

Important: During the operation of the controller, heat will be generated at the wiring terminal, incorrect wiring will cause safety hazards.

DO NOT

1. Don’t put wire under the terminal’s plate.
2. Don’t Put two or more wire in one termnial, each terminal only accpet one.
3. Don’t exposed copper outside the terminal; (The exposed copper wire needs to be tightly and completely connected to the terminal.)
4. The wiring must be tight and not loose.

Step 3: Connect the load, the load port can only be connected to the LED

lights (can not be connected)

LED lamp voltage value:

LED

| | 40A| 60A| 100A
---|---|---|---|---
**** Load power (W）| 12V Battery| ＜336W| ＜504W| ＜840W
24V Battery| ＜672W| ＜1008W| ＜1680W

• Load power should generally leave a 30% margin.
  • Example: 12V battery 100A controller, formula: 12V x 100A x 70% = load maximum power (W)
• Because the battery voltage is floating, LED lights at different voltages will not be the same brightness.
  • Example: 12v lithium battery to 12v bulb power supply, lithium battery is full of 12.8v, this time the LED lights will be brighter, when the battery work discharge voltage drop, the voltage value is lower than 12v or 11v, the light bulb will gradually become dark. When the battery power is too low, the bulb may flicker or go out directly. This time indicates that the battery power is low.

How to set lithium iron phosphate battery voltage?
Note: The controller defaults to lead acid batteries. If your batteries are lead-acid, no setting is required.

1.     Set lithium iron phosphate battery type : Short press the menu button 4 times ，Enter the battery type screen. .Long press  3 seconds Press the up button 1 time . .B03 is lithium iron phosphate battery.   

2. Setting the float voltage : Short press the menu button 1 time    Enter float voltage interface  Float voltage value flashing.
   Press and hold the menu button 3 seconds. Float charging voltage value does not flash, press up/down to adjust the parameter, set to 14.6V. automatically save.

3. Setting the discharge recovery voltage : Short press the menu button 2 times  .Enter the Discharge Recovery Voltage screen .Press and hold the menu button for 3 seconds  ,Discharge recovery power value does not flash, press up/down to adjust the parameter, set to 12V to save automatically.

4. Setting the discharge cut-off voltage : Short press the menu button 3 times .Enter the Discharge Cutoff Voltage screen    .Press and hold the menu button 3 seconds, the discharge
   cut-off voltage value does not flash, press up/down to adjust the parameter

and set it to 10V. automatically save.
At this point, congratulations on choosing Y&H. the controller is now working!
Step 5:Setting Load Working Mode

1. Short press the menu button 5 times .Enter the load working mode setting interface, long press the menu key for 3 seconds  . .Press up/down to set the mode.
2. Default【24H】for load normally open mode (except battery undervoltage)
3. 【1-23H 】 Light control + 1-23 hours timed off loads (lights turn on automatically at night and turn off after 1-23 hours)
4. 【0H】Pure light control mode (light off during the day, light on at night)

How to check the controller charging/discharging current?

1. Short press the menu button 6 times  ，Enter the working parameter    display interface
2. Press and hold the menu button for 3 seconds  .Interface does not flicker, Go to submenu.
3. Press the upturn key 2 down to enter the charging current display. Press the upturn key 3 down to enter the discharge current.
   Note: If the battery is fully charged, or the PV has no current. Both will not show the charging current
   Note: Cannot go back to the main interface  by entering the submenu. You need to press and hold the menu button for 3 seconds in the sub-menu interface. .After the value does not blink, press the scroll down key to return to the working parameter display interface.
