Charging principle
The battery is charged in several steps. The final charging voltage depends on the room temperature or the temperature on the
external temperature sensor 3. The final charging voltage decreases with a high temperature, the final charging voltage
increases with a low temperature.
The following explanation refers to a temperature of 22°C and a 12V battery system. A 24V-system requires double voltage
rates.
1.
Main charging phase
Up to a voltage of 14.1 V, the battery is charged with maximum current
2.
Timer phase
The battery is held on a voltage of 14,1V for several minutes. The duration of the timer phase is determined by the
type, age and quafity of the battery.
3.
Charge maintenance phase
In this phase, the solar charger applies pulses to the battery, thus loosening the generated sulfate layers (desulfation
function). In this process, the battery voltage is maintained on 13.7V.
4.
Standby phase
In this phase, there is no charging current. The voltage of the battery decreases slowly.
5.
Reactivation phase
After approx. 11 minutes (depending on the solar module) the solar controller is reactivated automatically.
The solar controller can also be reactivated manually by pressing button 1.
Assembly
In order to guarantee appropriate operation, please read these operating instructions including safety information completely
and carefully before use.
During assembly ensure that the solar controller and any other system components are mounted in such a way that it is not
accessible for children. Danger of life!
Do not mount the MPPT solar controller directly above a heat source! Ensure that the battery is located in a well ventilated
room! S trictly ensure correct polarity!
Always ensure proper ventilation of your solar controller. Never cover the ventilation slots of the solar controller. Never use the
device in the vicinity of highly flammable materials.
Remember that large amounts o f energy are stored in batteries. In case o f short-circuit, these energy quantities can be
released in a short time. This means that extreme heat may b uilt up or a fire may break out at the site o f short-circuit«
Connecting the solar controller
All components (solar module, battery, consumers and MPPT solar controller) must be adjusted to each other concerting
voltage and intensity of current. Check this information on the respective type plate. In case of doubt, please contact your
dealer.
S trictly ensure correct polarity!
If you connected the battery incorrectly, the red LED 9 lights up.
Note: In case of reverse polarity on the load output, devices without own protection may be destroyed. This is why each
consumer must be protected individually.
To ensure safe operation, please strictly follow the correct order, when connecting the individual system components.
1.
Connecting the battery:
Connect the battery with the MPPT solar controller by using the screw type terminals intended for this purpose. Make
sure you use a proper cable cross section to keep the voltage drop and heating of the cables as low as possible- The
screw type terminals are designed for cable cross sections of up to 16mm2 .
Required minimum cross sections:
1.5mm2 to 10A
2.5mm2 to 20A
4.0mm2 to 30A
Make sure that the line between battery and MPPT solar controller is fused according to instructions.
The solar controller is equipped with a temperature sensor 3 which must be mounted cirectiy on the battery housing.
The temperature sensor should also be mounted according to instructions when the battery is located directly next to
the solar controller, as the temperature on the battery housing may deviate from the ambient temperature. An
incorrectly measured temperature may cause controlling errors of the solar controler and may thus lead to
malfunctions.
2.
Connecting the solar module
Connect the solar module with the solar controller to the corresponding screw type terminals. The green LED 7 lights
up-
Please note that the maximum off-load voltage of the solar module is 60V.
When the battery status LEDs (4 ,5 ,6 ) are switched off, the solar controller is in standby mode.
The push button 1 is used to switch on the solar controller manually, i.e. to deactivate the standby mode.
Note: For this purpose, please note the following explanations of the standby function.
3.
Connecting the load
Please observe correct polarity when connecting the consumers!
Attention: Make sure that the load output o f the solar controller is switched off!
For this purpose, activate push button 1 and observe the LED displays for load output 8. When LED 8 does not light,
the load output is deactivated.
Note: Please note the following explanation of the function of push button 1.
Now connect the consumer load to the MPPT solar controller. For the terminal assignment please refer to the symbols
on the solar controller or the ¡lustration of the connection elements. Now the load output may be switched on or off
with push button 1 as required. When the load output is active, the green LED 8 is on.
