Starting up the controller
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.
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 10 V-1S V , 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 1S V) at start-up,
please refer to 8.2 Faults & Alarms
App installation
Search for “solarlife BT” in Google play or “solarlife” in Apple store and
download and install it. For detailed instruction and settings, please read
the Bluetooth APP user manual.
- Android APP
- iOS APP
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.
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°C/12V system parameters.
| Charging stage | Charging Voltage Range | Default charging voltage |
|---|---|---|
| Boost | 14.0-14.BV | 14.SV |
| Equalization | 14.0-15.0V | 14.8V |
| Float | 13.0-14.SV | 13.7V |
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)
(Overcharge Recovery Voltage+1.5V)<!:Lithium Overcharge Protection Voltage<!:(Overcharge Recovery Voltage+ 0.2V)
WARNING : The required accuracy of PCM shall be at least A\.. 0.2V. If the deviation is higher than 0.2V, the Lil manufacturer will assume no liability for any system malfunction caused by this.
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.
Lithium Battery
LVD range: 9.0-15.0V(default: 9.0V).
Gel, Liquid and AGM Battery
The low voltage protection of the controller can be divided into two types:
battery voltage control and capacity control.
Battery voltage control
Low voltage disconnect setting range: 10.8-11.BV (default: 11.2V).
Battery capacity control
Low voltage disconnect setting range: Soc1 ~Socs
| Soc | Low voltage protection range |
|---|---|
| Soc1 | 11.0~11.6V |
| Soc2 | 11.1~11.7V |
| Soc3 | 11.2~11.8V |
| Soc4 | 11.4~11.9V |
| Socs | 11.6~12.0V |
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.
Lithium Battery
LVR range: 9.6~16.0V.
Gel, Liquid and AGM Battery
LVR range: 11.4~12.8V. The low voltage recovery voltage(LVR) should .
At be higher than the low voltage disconnect **** voltage(LVD) at least 0.6V,
if you want to improve LVD, you should first improve LVR.
0°C Charging(Lithium)
“0°C Chg” can be set to “Yes”, “Slow” or “No”. When the controller detects
that the ambient temperature is higher than 0°C, the charging function is
normal. when the ambient temperature is low than 0°C, if the “0°C Chg” is set
to “Yes”, the charging function is normal, else if the “0°C Chg” is set to
“slow”, the max charging current is 20% of the rated current, else if the “0°C
Chg” is set to “No”, the controller does not charge the battery. The user can
select the appropriate charging method.

Warning : It is forbidden to short-circuit the PV array during charging
.Otherwise, the controller may be damaged. *3. 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.
Safety Instructions and Liability Waiver
Safety
- 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.
- 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.
- Batteries can produce flammable gases. Avoid sparks and flames near the batteries. Make sure the battery is installed in a well ventilated area.
- 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.
- 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
