USB To RS-485 converter is used to monitor each controller on the network using
Solar Station PC software and update the firmware. The length of cable is 1.5m.
The CC-USB-RS485-150U connects to the RS-485 Port on the controller.
1.4 Maximum Power Point Tracking Technology
Due to the nonlinear characteristics of solar array, there is a maximum energy
output point (Max Power Point) on its curve. Traditional controllers, with switch
charging technology and PWM charging technology, can‘t charge the battery at
the maximum power point, so can‘t harvest the maximum energy available from
PV array, but the solar charge controller with Maximum Power Point Tracking
(MPPT) Technology can lock on the point to harvest the maximum energy and
deliver it to the battery.
The MPPT algorithm of our company continuously compares and adjusts the
operating points to attempt to locate the maximum power point of the array. The
tracking process is fully automatic and does not need user adjustment.
As the Figure 1-2, the curve is also the characteristic curve of the array, the
MPPT technology will ‗boost‘ the battery charge current through tracking the MPP.
Assuming 100% conversion efficiency of the solar system, in that way, the
following formula is established:

4
Input power (PPV)= Output power (PBat)
Input voltage (VMpp) *input current (IPV) =Battery voltage (VBat) *battery current (IBat)
Normally, the VMpp is always higher than VBat, Due to the principle of conservation
of energy, the IBat is always higher than IPV. The greater the discrepancy between
VMpp &VBat, the greater the discrepancy between IPV& IBat. The greater the
discrepancy between array and battery, the bigger reduction of the conversion
efficiency of the system, thus the controller‘s conversion efficiency is particularly
important in the PV system.
Figure 1-2 is the maximum power point curve, the shaded area is charging range
of traditional solar charge controller (PWM Charging Mode), it can obviously
diagnose that the MPPT mode can improve the usage of the solar energy
resource. According to our test, the MPPT controller can raise 20%-30%
efficiency compared to the PWM controller. (Value may be fluctuant due to the
influence of the ambient circumstance and energy loss.)
In actual application, as shading from cloud, tree and snow, the panel maybe
appear Multi-MPP, but in actually there is only one real Maximum Power Point. As
the below Figure 1-3 shows:
Figure 1-2 Maximum Power Point Curve

5
If the program works improperly after appearing Multi-MPP, the system will not
work on the real max power point, which may waste most solar energy resources
and seriously affect the normal operation of the system. The typical MPPT
algorithm, designed by our company, can track the real MPP quickly and
accurately, improve the utilization rate of the array and avoid the waste of
resources.
1.5 Battery Charging Stage
The controller has a 3 stages battery charging algorithm (Bulk Charging, Constant
Charging and Float Charging) for rapid, efficient, and safe battery charging.
Figure 1-3 Mutil-MPP Curve
Figure 1-4 Battery changing stage Curve

6
A) Bulk Charging
In this stage, the battery voltage has not yet reached constant voltage (Equalize or
Boost Voltage), the controller operates in constant current mode, delivering its
maximum current to the batteries (MPPT Charging).
B) Constant Charging
When the battery voltage reaches the constant voltage setpoint, the controller will
start to operate in constant charging mode, this process is no longer MPPT
charging, and in the meantime the charging current will drop gradually, the
process is not the MPPT charging. The Constant Charging has 2 stages,
equalize and boost. These two stages are not carried out constantly in a full
charge process to avoid too much gas precipitation or overheating of battery.
Boost Charging
The Boost stage maintain 2 hours indefault, user can adjust the constant time and
preset value of boost voltage according to demand.
The stage is used to prevent heating and excessive battery gassing.
Equalize Charging
WARNING: Explosive Risk!
Equalizing flooded battery would produce explosive gases, so well
ventilation of battery box is recommended.
CAUTION: Equipment damage!
Equalization may increase battery voltage to the level that
damages sensitive DC loads. Verify that all load allowable input
voltages are 11%greater than the equalizing charging set point
voltage.
CAUTION: Equipment damage!
Over-charging and excessive gas precipitation may damage the
battery plates and activate material shedding on them. Too high an
equalizing charge or for too long may cause damage. Please
carefully review the specific requirements of the battery used in
the system.
AVERTISSEMENT: Risque d‘explosion!
l'égalisation de batteries noyées peut produire des gaz explosifs,
donc il est recommandéde bien ventiler le boitier de la batterie.

7
ATTENTION: Dégât sur l'équipement!
L'égalisation peut augmenter la tension de la batterie jusqu'àun
niveau nuisible pour les charges CC sensibles. Vérifiez que la
tension d'entrée autorisées de toutes les charges disponibles sont
supérieures à11% àla tension du point d'installation de
chargement d'égalisation.
ATTENTION: Dégât sur l'équipement!
Un chargement excessif et une précipitation de gaz peut
endommager les plaques de la batterie et la formation de matières
actives dessus. Un chargement trop fort ou une égalisation
prolongée peut causer des dégâts. Inspectez soigneusement les
conditions spécifiques de la batterie utilisée dans le système.
Some types of batteries benefit from equalizing charge on a regular basis, which
is able to stir electrolyte, balance battery voltage and accomplish chemical
reaction. Equalizing charge increases battery voltage, higher than the standard
complement voltage, which gasifies the battery electrolyte.
The controller will equalize the battery on the 28th each month. The constant
equalization period is 0~180 minutes. If the equalization isn‘t accomplished in
one-time, the equalization recharge time will be accumulated until the set time is
finished. Equalize charge and boost charge are not carried out constantly in a full
charge process to avoid too much gas precipitation or overheating of battery.
Note:
1) Due to the influence of ambient circumstance or load working, the battery
voltage can’t be steady in constant voltage, controller will accumulate and
calculate the time of constant voltage working. When the accumulated time
reach to 3 hours, the charging mode will turn to Float Charging.
2) If the controller time is not adjusted, the controller will equalize charge
battery once every month following the inner time.
C) Float Charging
After the Constant voltage stage, the controller will reduce charging current to
Float Voltage setpoint. This stage will have no more chemical reactions and all
the charge current transforms into heat and gas at this time. Then the controller
reduces the voltage to the floating stage, charging with a smaller voltage and
current. It will reduce the temperature of the battery and prevent the gassing and
charging the battery slightly at the same time. The purpose of Float stage is to
offset the power consumption caused by self consumption and small loads in the
whole system, while maintaining full battery storage capacity.
In Float charging stage, loads are able to obtain almost all power from solar panel.
If loads exceed the power, the controller will no longer be able to maintain battery
voltage in Float charging stage. If the battery voltage remains below the Recharge
Voltage, the system will leave Float charging stage and return to Bulk charging
stage.

and clean any contact with battery acid.
Keep the battery away from any metal objects, which may cause short circuit of
the battery.
Explosive battery gases may come out from the battery during charging, so
make sure ventilation condition is good.
Gel, Sealed or Flooded batteries are recommended, other kinds please refer to
the battery manufacturer.
Ventilation is highly recommended if mounted in an enclosure. Never install the
controller in a sealed enclosure with flooded batteries! Battery fumes from
vented batteries will corrode and destroy the controller circuits.
Loose power connections and corroded wires may result in high heat that can
melt wire insulation, burn surrounding materials, or even cause fire. Ensure
tight connections and use cable clamps to secure cables and prevent them from
swaying in mobile applications.
Battery connection may be wired to one battery or a bank of batteries. The
following instructions refer to a singular battery, but it is implied that the battery
connection can be made to either one battery or a group of batteries in a battery
bank.
Multiple same models of controllers can be installed in parallel on the same
battery bank to achieve higher charging current. Each controller must have its
own solar module(s).
Select the system cables according to 5A/mm2or less current density in
accordance with Article 690 of the National Electrical Code, NFPA 70.
2.2 PV Array Requirements

NOTE: The above parameter values are calculated under standard test
conditions (STC (Standard Test Condition)：Irradiance 1000W/m2，Module
Temperature 25℃，Air Mass1.5.)
PV array maximum power
This MPPT controller has a limiting function of charging current, the charging
current will be limited within rated range, therefore, the controller will charge the
battery with the rated charging power even if the input power at the PV exceeds.
The actual operation power of the PV array conforms to the conditions below:
1）PV array actual power ≤ controller rated charge power, the controller charge
battery at actual maximum power point.
2）PV array actual power > controller rated charge power, the controller charge
battery at rated power.
If the PV array higher than rated power, the charging time at rated power to battery
will be longer, more energy to battery yields.
WARNING: Controller will be damaged when the PV array straight
polarity and the actual operation power of the PV array is three times
greater than the rated charge power!
WARNING: Controller will be damaged when the PV array reverse
polarity and the actual operation power of the PV array is 1.5 times
greater than the rated charge power!
Whenthe PV array straight polarity, the actual operation of the PV array must NOT
exceed three times of rated charge power, Whenthe PV array reverse polarity, the
actual operation must NOT exceed 1.5 times. For real application please refer to

2.3 Wire Size
The wiring and installation methods must conform to all national and local
electrical code requirements.
PV Wire Size
Since PV array output can vary due to the PV module size, connection method or
sunlight angle, the minimum wire size can be calculated by the ISC of PV array.
Please refer to the value of ISC in PV module specification. When the PV modules
connect in series, the ISC is equal to the PV module‘s ISC. When the PV modules
connect in parallel, the ISC is equal to the sum of PV module‘s ISC. The ISC of PV
array must not exceed the maximum PV input current, please refer to the table as

4 Protections, Troubleshooting and Maintenance
4.1 Protection
PV Over Current
The controller will limit battery charging current to the Maximum Battery Current
rating. Therefore an over-sized solar array will not operate at peak power.
PV Short Circuit
When PV short circuit occurs, the controller will stop charging. Clear it to resume
normal operation.
PV Reverse Polarity
Fully protection against PV reverse polarity, no damage to the controller will
result. Correct the miswire to resume normal operation.
WARNING: Controller will be damaged when the PV array reverse
polarity and the actual operation power of the PV array is 1.5 times
greater than the rated charge power!
Battery Reverse Polarity
Fully protection against battery reverse polarity, no damage to the controller will
result. Correct the miswire to resume normal operation.
Battery Over voltage
When battery voltage reach to the voltage set point of Over Voltage Disconnect
Voltage, the controller will stop charging the battery to protect the battery
overcharge to break down.
Battery Over discharge
When battery voltage reach to the voltage set point of Low Voltage Disconnect
Voltage, the controller will stop discharging the battery to protect the battery over
discharged to break down.
Battery Overheating
The controller detect the battery temperature through the external temperature
sensor. If the battery temperature exceeds 65ºC, the controller will automatically
start the overheating protection to stop working and recover below 50 ºC.
Load Overload
If the load current exceeds the maximum load current rating 1.05 times, the
controller will disconnect the load. Overloading must be cleared up through
reducing the load and restarting controller.
Load Short Circuit
Fully protected against load wiring short-circuit. Once the load shorts (more than
quadruple rate current), the load short protection will start automatically. After five
automatic load reconnect attempts, the fault must be cleared by restarting
controller.
