Product Usage Instructions

1. Step 1: Solar Panel Connection
   Make sure the solar panel voltage is higher than the battery voltage before connecting.

2. Step 2: Solar Panel Voltage Selection
   Choose the appropriate solar panel voltage based on the battery system to ensure compatibility and safety.

3. Step 3: Battery Connection
   Connect the battery to the controller. The system will automatically detect the DC system voltage. Adjust settings if using a non-lead-acid battery.

4. Step 4: Load Connection
   Connect the load port to LED lights only. Ensure proper voltage matching for the LED lights.

Frequently Asked Questions (FAQ):

• Q: Can I connect multiple wires to one terminal?
  A: No, each terminal should only accept one wire. Do not put multiple wires in one terminal.

• Q: How should I wire the system for safety?
  A: Do not expose copper outside the terminal and ensure tight and secure wiring connections. Follow the provided wiring guidelines for safety.

SY controller wiring and setting tutorial

Button introduction

How to use Y&H SY series controller?

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/36V/48V 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 terminal, each terminal only accept 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 lights use power：

Load power

(W)

| 60A| ＜504W| ＜1008W| ＜1512W| ＜2016W
80A| ＜672W| ＜1344W| ＜2016W| ＜2688W
100A| ＜840W| ＜1680W| ＜2520W| ＜3360W

• 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.

Step 4:Setting charging cut-off voltage/discharging cut-off voltage

The controller defaults to the lead-acid battery type. Lead-acid batteries can be wired directly for use. Other battery types require a charging cut-off voltage to be set. Discharge cut-off voltage can not be adjusted (some customers do not want to over-discharge the battery, you can adjust the discharge cut-off voltage voltage value)
Charge cut-off voltage of various battery types: (different manufacturers may have errors in battery parameters)

lead-acid battery| li-ion battery| lithium iron phosphate battery| Ternary Battery
---|---|---|---
14.2V-14.6V(tunable)| 12.8V| 14.6V| 12.6V

Note: The voltage marked in red above corresponds to 12V system only. If using (24V system, please X 2), (36V system, please X 3) (48V system, please X 4)

Necessarily setting the charging cut-off voltage (e.g. lithium iron phosphate battery)
Connect the battery, after the screen lights up, long press “▲” for five seconds, when the value next to “H” is flashing, press “▼” to adjust the value of charging voltage, keep pressing “▼” to adjust the value to 14.6V, and finally press “■” to confirm and save. Keep pressing “▼” to adjust the value to 14.6V, and finally press “■” to confirm and save.(According to the actual charging cut-off voltage of your own battery to set)

Discharge cut-off voltage setting（”L” is the cut-off discharge voltage value, below which the battery stops discharging and the load will stop working.）
Long press the key “▲” for five seconds, after the appearance of the word “H”, short press “▲” for a while, the appearance of “L” next to the value of the flashing, press “▼” to set the value of the discharge voltage, and finally press “■” to confirm the preservation.

At this point, congratulations on choosing Y&H. the controller is now working!

Load Mode Function Description

1. “Charging” means the controller is working in charging mode.
2. “Light Control” means the controller is working in light control mode.
3. “Light Control and delay” means the controller is working in Light Control start + delay stop control mode.
4. “Universal Control” means the controller is working in universal control mode.
5. “Manual” means the controller is working in manual control mode.
6. “Timing” indicates that the controller is working in timing control mode.
7. “Test” indicates that the controller is working in test mode.
