The operating instructions must be read and understood by all persons and specialists who work with this device and all points must be observed.
Do not try to disassemble the device. It contains no user-serviceable parts. During installation, operation or maintenance carried out by qualified personnel, observe the local safety instructions and the relevant laws. Otherwise personal injury or equipment damage may occur.
The safety instructions in this manual serve as a supplement to the local safety instructions. Our company assumes no liability for damage caused by non- observance of the safety instructions.
This also applies if no regular maintenance or maintenance/repairs were not carried out by qualified specialist personnel. The device must also be set up by qualified specialist personnel.
The solar charge controller may only be used in photovoltaic systems that comply with these operating instructions. Likewise, only solar modules that meet the requirements of the controller may be used. No other energy sources may be connected to the solar charge controller.
Any further use or use that goes beyond this is considered to be improper and can lead to personal injury, damage to property and/or damage to the device.
The batteries store a large amount of energy. Therefore, be careful not to short-circuit the battery.
We recommend installing a fuse or circuit breaker on the positive (+) terminal between the battery and ESC. The fuse or switch should not be more than 15 cm from the battery post.
Batteries can produce flammable gases (oxyhydrogen). Therefore, avoid sparks and/or flames near the battery.
Make sure the battery is in a well-ventilated place.

Avoid touching or shorting wires or terminals.

The voltage on wires or terminals can be many times higher than the battery voltage itself.
Only use insulated tools.
Keep children away from all electrical devices/connections etc.

Dimensions

Installation

Make sure the cable lengths between the battery and the controller are as short as possible. Make sure that the cable cross- section is sufficient and that you connect it in the correct order:

First connect the load with the corresponding cables
(positive pole=red (1) // negative pole=black (2)). Then isolate them with a suitable insulating tape (not included).
Then connect the It applies again (positive pole=red (3) // negative pole=black (4)).

The load should now be switched on.

Connect the solar panel with the positive cable (5) and the negative cable (6).
The controller starts charging.
Check the status of the LED display (see section 10).
Commissioning of the controller

Self-Test

As soon as the charge controller draws power for the first time, it starts a self-test.
It then automatically switches to normal operation.

System Voltage

The charge controller can be used for lithium, gel, AGM and wet batteries.
The default is Gel. Therefore, please make absolutely sure that the charge controller is set appropriately for your battery. If the setting does not match the characteristic of the battery, change it accordingly.
If the controller is set to gel, wet, AGM or lithium battery and the battery voltage is 10-15V when switched on, the charge controller will set a 12V system. If the battery voltage is not between 10-15 V, please read point 11. (Troubleshooting).

Installation of the App

To install the app, search for “solarlifeBT” in your Playstore (Android phone) and “solarlife” in the App Store (iOS). For detailed explanations and settings, please read the user manual of the Bluetooth app.

Bluetooth

The controller has a Bluetooth communication function. After successfully installing the app, the controller can be connected to the mobile phone via Bluetooth.
For detailed instructions, please read the instructions in the Bluetooth app.
With the help of the app, you can set the parameters, including the devices and battery parameters. The operating status of the control unit is also displayed in real time.

Charging voltage wet, gel, AGM battery

With the charging voltages wet, gel or AGM battery, you must set the parameters for boost, equalization and float voltage via the app.
The following voltage parameters apply to 25°C/12V systems:

charge level

boost equalizing charge float voltage

area of charging voltage

14.0-14.8V 14.0-15.0V 13.0-14.5V

default charging voltage

14.5V 14.8V 13.7V

Lithium charging voltage

You can set the overcharge protection and overcharge recovery voltage of the lithium battery through the app. Overcharge Protection (CVT): 10.0-17.0V Overcharge Recovery Voltage (CVR): 9.0-16.8V

Overcharge Recovery Voltage + 1.5V>Lithium
Overcharge Protection Voltage > Overcharge Recovery Voltage + 0.2V.
If the deviation is greater than 0.2V, the manufacturer assumes no liability for a system malfunction caused by this.

Under Voltage Lockout (LVD)

To prevent deep discharge of the load, the controller turns off the load as soon as the battery voltage falls below the LVD voltage. Should this happen, the battery must be fully charged before using it again.

Lithium batteries: LVD=9.0-15.0V (default: 0V)
Gel, wet and AGM batteries:

The low voltage protection of the controller can be divided into two types: a. Battery voltage control:
Low voltage cut-off adjustment range: 10.8-11.8V (default: 11.2V) b. Battery capacity control: Setting range of undervoltage shutdown: SoC 1 – SoC 5

SoC status

SoC 1 1 1.0 – 11.6V
SoC 2 11.1-11.7V
SoC 3 11.2 – 11.8V
SoC 4 11.4-11.9V

Low Voltage Reclosing (LVR)

If the undervoltage lockout is triggered, the controller will not reestablish the charge connection until the battery voltage is above the LVR voltage.

Lithium batteries: LVR= 9.6 to 16.0 V 2.
Gel, wet and AGM batteries: LVR= 11.4 to 12.8 V
The LVR should be higher than the LVD.
The LVD should be at least 0.6V.

If you want to change the LVD, you must first change the LVR.

8.50°C Charge (Lithium)

The 0°C charge can be set to “Yes”, “No”, or “Slow”.
If the temperatures are higher than 0°C, the normal charging mode is used. However, when temperatures are below 0°C, the following applies

charge mode charge

**** Yes Battery can be charged normally
Slow Max. charging current is 20% of the rated current
no Battery cannot be charged

Day/Night Threshold and day/night delay

Based on the open-circuit voltage of the solar system, the charge controller recognizes day and night. The day/night threshold can be adjusted depending on the lighting conditions.
Threshold setting range: 3.0 to 8.0 V.
The threshold can be delayed by up to 30 minutes using the day/night delay.

The load shedding threshold voltage is 1V higher than the setting data.
This means that the load will be cut off when the solar voltage is between 4.0V to 9.0V.
The controller automatically adjusts the threshold voltage.
On the first night, the load will have no power. 24 hours later, the controller automatically adjusts the setting to deliver power the following night.

Charge Modes

Mode: Always on

Mode: Dusk to Sunrise

With this charging mode, the day/night threshold values and the day/night delay can be set. The load can be switched on or off by the test function during the day during the charging process.

5-level mode

Times 1-5 can be set individually to allow variable load performance at night. if e.g.
Time 4 is set to “TOT” (Time/Operation/Time), time 4 is removed. The system then takes at time 4 the data from time 5 and previous data about the time of sunrise.

If the controller turns off the load due to under-voltage protection, over- current protection, short- circuit protection or over-temperature protection, the load will automatically turn on again when the charge controller exits the protection state

Manual operation

If the load mode is set to manual, you can turn on/off the load output manually via the Bluetooth app.
