3. Installation

The following diagram provides an overview of the terminals. Please make sure to follow the proper order of connection.

1. As the chart, Connect the load first with corresponding red(positive) and black (negative) cables, then seal them with tape.
2. Connect the battery with corresponding positive and negative cables, load will be on.
3. Connect panel with the corresponding red(positive) and black( negative) cables, the controller begins charging.
4. Confirm the LED display status, please refer to the 8.2 Faults and Alarms to identify the reason.

Make sure the wire length between battery and controller is as short as possible. Recommended Wire size: 2.5mm²

4. Starting up the controller

4.1 Self Test
As soon as the controller is powered, it starts a self test routine. After this, the LED display will change to normal operation.

4.2 System Voltage
The controller applies to Lithium, AGM, Liquid and Gel battery, the factory default setting is suitable for Gel battery. It is your responsibility to check and ensure that these settings are correct for your battery, otherwise they must be amended.

When the controller is set to Lithium battery, the charging target voltage and charging recovery voltage can be set according to customer requirements.

If the battery voltage on start-up is 10V-15V , the controller infers a 12V system when the controller is set to Gel, Liquid or AGM battery. If the battery voltage is not within the normal operating rang(ca.10 to 15V) at start-up, please refer to 8.2 Faults & Alarms.

5. App installation

Search for “solarlife” in the app market and download and install it. For detailed instruction and settings, please read the Bluetooth APP user manual.

Andriod APP

iOS APP

6. Bluetooth

The controller has Bluetooth communication function, the Bluetooth module of the controller can be connected to mobile phone after installing APP.

For detailed operation, please read the “Bluetooth APP instructions ” . App on mobile phone can view the real time working state of the controller and set parameters, including device and battery parameters.

6.1 Charging Voltage (Liquid/ GEL/AGM)
When choosing Liquid, GEL or AGM for battery type, the parameters of boost, equalization and float charging voltage can be set by mobile phone APP. The range of parameters is as follows.

The following voltage parameters are 25℃/12V system parameters.

6.2 Charging Voltage Parameters(Lithium)
When choosing lithium battery type, the overcharge protection and overcharge recovery voltage of lithium battery can be set by mobile phone APP.

Overcharge protection voltage(CVT): 10.0-17.0V
Overcharge recovery voltage(CVR): 9.2-16.8V.

(Overcharge Recovery Voltage+1.5V)≥ Lithium Overcharge Protection Voltage≥(Overcharge Recovery Voltage+0.2V)

The required accuracy of PCM shall be at least 0.2V. If the deviation is higher than 0.2V, the manufacturer will assume no liability for any system malfunction caused by this.

6.3 Low Voltage Disconnect (LVD)
When the battery voltage drops below the LVD voltage, the controller will disconnect the load to prevent deep discharge of the battery. If this occurs, the battery should be well charged before resuming use.

1. Lithium Battery
LVD range: 9.0~15.0V(default: 9.0V).

2. Gel, Liquid and AGM Battery
The low voltage protection of the controller can be divided into two types: battery voltage control and capacity control.

a. Battery voltage control
Low voltage disconnect setting range: 10.8~11.8V (default: 11.2V).

b. Battery capacity control
Low voltage disconnect setting range: Soc1~Soc5

6.4 Low Voltage Reconnect (LVR)
If the low voltage disconnect is triggered, the controller will restore load connection only when the battery voltage increases above the LVR voltage.

1. Lithium Battery
   LVR range: 9.6~16.0V.

2. Gel, Liquid and AGM Battery
   LVR range: 11.4~12.8V.

The low voltage recovery voltage(LVR) should be higher than the low voltage disconnect voltage(LVD) at least 0.6V, if you want to improve LVD, you should first improve LVR.

6.5 0℃ Charging (Lithium)
“0℃ Chg” can be set to “Yes”, “Slow” or “No”. When the controller detects that the ambient temperature is higher than 0℃, the charging function is normal. when the ambient temperature is low than 0℃, if the “0℃ Chg” is set to “Yes”, the charging function is normal, else if the “0℃ Chg” is set to “slow”, the max charging current is 20% of the rated current, else if the “0℃ Chg” is set to “No”, the controller does not charge the battery.

The user can select the appropriate charging method.

6.6 Day/Night Threshold, Day/Night Delay
The controller recognizes day and night based on the solar array open circuit voltage. This day/night threshold can be modified according to local light conditions and the solar array used.

Day/Night threshold setting range: 3.0~8.0V.
The actual time of turning on can be delayed by up to 30 minutes from the time the threshold was reached using the Day/Night delay setting (D/N delay).

Day/Night delay time setting range: 0~30min.

• Day/Night threshold voltage of load disconnect is 1V higher than the setting data, means the load will disconnect when the solar voltage at 4.0~9.0V.
• The controller will automatically adjust the day/night threshold. If the lowest solar voltage is higher than the day/night threshold. The load will have no output the first night, then 24 hours later the controller will automatically adjust the setting to give output the following night.

7. Load Modes

7.1 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).

7.2 Street Lamp Function

When the load is set to D2D(Dusk to Dawn) or Evening mode, the Day/Night threshold voltage and the

Day/Night delay time can be set, and the load can be turned on or off by the test function during the day charging process.

7.3 Five-stage Mode

Time 1-5 and Dim 1-5 can be set individually to give variable load power throughout the night.

*If “Time4” is set to “T0T”, this mode is T0T mode, the controller will determine Time4 based on Time5 and previous data on the time of sunrise.

7.4 Manual Mode
If the load mode is selected “Manual”, then you can switch on and off the load output manually by bluetooth APP.

If the controller turns off the load due to low voltage protection、over current

8. LED indicators, Faults & Alarms

9. Safety Features

1. Controller can protect itself, but load might be damaged.
2. Battery must be protected by fuse.

Warning:
The combination of different error conditions may cause damage to the controller.
Always remove the error before you continue connecting the controller.

10. Safety Instructions and Liability

10.1 Safety

1. The solar charge controller may only be used in PV systems in accordance with this user manual and with solar panels specifications in line with the requirements of this controller. No energy source other than solar panels may be connected to the solar charge controller.
2. Batteries store a large amount of energy, never short circuit a battery under any circumstances. We strongly recommend connecting an in-line fuse or circuit-breaker on the “+” wire between the battery and controller, no more than 15cm from the battery terminal.
3. Batteries can produce flammable gases. Avoid sparks and flames near the batteries. Make sure the battery is installed in a well ventilated area.
4. Avoid touching or short circuiting wires or terminals. Be aware that the voltages on special terminals or wires can be several times greater than the battery voltage. Use isolated tools and only perform any work in a dry environment.
5. Keep children away from batteries and the charge controller.

Liability Exclusion
The manufacturer shall not be liable for damages to the controller or battery caused by use other than as instructed in this manual, or if the battery manufacturer’s recommendations are neglected. The manufacturer shall not be liable if there has been service or repair carried out by any unauthorised person, unusual use, incorrect setup, or bad system design.

11. Technical Data

1. PV panel Voc can not exceed this value, otherwise it will damage the controller.
2. Voc means the open circuit voltage of the solar panel.
