3. Functions of the solar charge controller

Power supplied (Pmax) = solar charge controller output power (Pout)
Grid-connected solar modules can also be used as long as the open circuit voltage
of the solar system does not exceed the maximum input voltage at the worst case
(coldest) module temperature.
3.1 MPPT technology current
amplification MPPT
technology enables the PV charging current to be increased.
Assuming 100% efficiency.
It is possible to set different load modes.
For example, a 12 V battery with a nominal voltage of 12 V / 24 V / 36 V or 48 V
can be charged.
The documentation of the solar modules should contain corresponding data
depending on the temperature.
Iin x Vmp = lout x Vout
Higher PV input voltage results in lower PV input current for a given input power.
If the maximum power voltage of the solar panel (Vmp) is greater than the battery
voltage, the battery current must be proportionately greater than the solar input
current to balance the input and output power.
Monthly load data can be displayed as a summary in the form of graphics.
(Always on, dusk, evening and manual).
In fact, there are slight losses in wiring and conversion.
Another advantage of MPPT technology is the charging of batteries with PV
modules of a higher nominal voltage.
A fully automatic electronic protection function ensures increased reliability of the
solar charge controller.
The greater the difference between Vmp and battery voltage, the greater the current
gain. Current gain can be significant in systems where the solar array is rated at a
higher voltage than the battery.
The RS-485 standard protocol Modbus with RJ11 interface enables optimal
communication in various applications.

The Vmp of a PV module decreases with increasing temperature.
In very hot weather the Vmp can be close or even below the battery voltage. Under
these conditions, the MPPT gain is very low or non-existent compared to
conventional solar charge controllers.
Because traditional solar charge controllers are not always operating at the Vmp
of the solar array, energy is wasted that could otherwise be used to charge the
battery and power grid loads.
However, in systems with modules whose rated voltage is higher than the battery
voltage, the Vmp of the solar array will always be higher than the battery voltage.
A higher PV input voltage enables a smaller cross-section of the PV wiring. This is
particularly helpful and economically interesting for systems with long cable runs
between the solar charge controller and the solar system.
The greater the difference between the battery voltage and the Vmp of the module,
the more energy is wasted.
In contrast to conventional PWM solar charge controllers (pulse width modulation),
the a-TroniX solar charge controller can reproduce the maximum output of the PV
module, so that a larger charging current can be supplied. In general, the energy
efficiency of the solar charge controller is 15% to 20% higher than that of the PWM
solar charge controller.
Conventional solar charge controllers connect the PV module directly to the battery
when charging. This requires the PV module to operate in a voltage range that is
typically below the module's Vmp value.
For example, in a 12 V system, the battery voltage can range from 10.8 V to 15.0
V, but the maximum power voltage (Vmp) values of PV modules are typically 16 V
to 17 V.

3.2 MPPT - Four Stage Charging Process
operation manual
Trickle Store (Float)
Fast Charge (Boost)
page 11
02/2022
When the battery is fully charged, the desired chemical reactions no longer occur in
the battery and the charging current is converted to heat and gas.
After the "boost" charging process, the solar charge controller reduces the voltage
setpoint to "trickle charging".
Once charging reaches the “boost” voltage set point, constant voltage regulation
is applied to prevent battery heating and excessive gassing. By default, fast charging
takes about 2 hours and then switches to trickle charging (“float”).
The purpose of the “Float” stage is to balance the current consumption due to self-
consumption and small loads in the entire system and to obtain full battery storage
capacity in a timely manner. Float charging allows loads to continue drawing current
from the battery. If the system loads exceed the PV charge current, the solar
charge controller will no longer be able to keep the battery at the float charge
setpoint. If the battery voltage remains below the quick recharge voltage, the
charge controller exits trickle charging and returns to charging mode.
For this reason, the charge controller sets the charging voltage to "trickle charging"
so that charging is carried out with a reduced voltage and current.
Each time the solar charge controller is switched on, the charging process changes
to the "boost" charging stage, provided no overdischarge or overvoltage is detected.
The solar charge controllers of the a-TroniX series have a 4-stage battery charging
algorithm for fast, efficient and safe battery charging.
This process lowers the temperature of the battery and prevents gas formation.
MPPT charging
In this phase, the battery voltage has
not yet reached the "boost" charging
voltage and 100% of the available PV
energy is used to charge the battery.
At the same time, the battery is slightly charged.

Equalization (Equilization)
operation manual
page 12 02/2022
There is a risk of explosion!
Explosive gases may be generated when equalizing a fully charged battery. Good
ventilation of the battery is therefore necessary.
By default, this takes about 2 hours.
Equalizing charge and quick charge are not performed continuously in each full charge to avoid
over-voltage and/or overheating of the battery.
Certain battery types benefit from periodic equalization charging.
WARNING:
By balancing the charge, the battery voltage increases.
This is higher than the standard complementary voltage, which converts the battery electrolyte
into gas. When the battery is detected to be overcharged, the solar charge controller will
automatically switch the battery to equalization charge.

Explosion Hazard: There is a risk of fire or explosion if the battery terminals or cables
are shorted.
WARNING:
The PV module can exhibit open circuit voltages of more than 100 V when exposed
to sunlight. Watch out for this hazard.
First, drill the 4 mounting holes according to the installation positions in “5. Device description”
on the wall.
The inside temperature is automatically displayed if no solar charge controller is
connected. An inverter must always be mounted directly on the battery, never on the
load terminals of the solar charge controller.
WARNING:
DANGER:
Then attach the solar charge controller to the pre-drilled holes.

Voltages are noticeable when the controller is set to a lithium battery.
With a nominal voltage of 12 VDC, the battery voltage should be in the range of 5.0
to 15.5 VDC.
When connecting the PV module, make sure that it is protected from direct sunlight.
Make sure that the PV module does not exceed the maximum permissible input
current of the solar charge controller (see section "Technical data").
Connect the load cable to the right pair of terminals on the solar charge controller with
the correct polarity.
If the polarity is set correctly, these are displayed on the LCD of the solar charge
controller.
With a nominal voltage of 24 V DC, the battery voltage should be in the range of
20.0 to 31.0 V DC.
To avoid tension in the cables/wires, first connect them to the load before connecting
them to the solar charge controller.
1. Connect the temperature sensor cable.
With a nominal voltage of 36 VDC, the battery voltage should be in the range of 31.0
to 42.0 VDC.
Connect the solar module connection cable to the solar charge controller with the
correct polarity of the left pair of clamps (solar module symbol). Pay attention to the
requirements of the mounting location.
2. Then connect the cable for the RS485 communication.
With a nominal voltage of 48 VDC, the battery voltage should be in the range of 40.0
to 62.0 VDC.
Connect the battery to the middle pair of terminals on the solar charge controller with
correct polarity. Never reverse the positive (+) and negative (-) poles.
