Installation

 General Installation Notes

•  Before you begin installation please read through the entire installation instructions to familiarise yourself with the installation steps.
•  Be very careful when working with batteries, especially flooded lead-acid batteries. Wear eye protection and have fresh water available to wash with in case of any contact with battery acid.
•  Keep the battery away from any metal objects which may cause a short circuit of the battery terminals.
•  Explosive battery gases may be released out from the battery during charging, therefore  sufficient ventilation is vital.
•  This controller has been designed for lead acid batteries, with programs for Gel, Sealed and Flooded battery types. It also supports a User defined battery type for models of lead acid batteries that need customized settings. In order to choose the right battery program and charging voltage for your battery please refer to the battery supplier or manufacturer.
•  Ventilation is highly recommended when mounting the controller in an enclosure. Never install the controller in a sealed enclosure with flooded batteries! Battery gases from flooded batteries may cause corrosion and destroy the controller circuits, as well as increase the risk of explosion.
•  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 unnecessary movement.
•  Battery connecting cables may be wired to one battery or a bank of batteries. This user manual always refers to a single 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.
•  This model of the solar charge controller allows for the installation of more solar charge controllers in parallel (all controllers should be identical), connected to the same battery bank, to achieve a higher charging current. Each controller must have its own solar panel(s). The battery (bank) should be able to accept combined current from all controllers.
•  Select the system cables according to 5A per 1 mm2 cross-section or less current density in accordance with this manual and all the appropriate regulations and national guidelines.

 PV Array Requirements

1. Series connection (string) of PV modules
   The maximum number of PV modules which can be connected in series and fed into this solar charge controller can be calculated according to the open circuit voltage (Voc) of the PV module and the maximum power point voltage (VMpp) of the controller. The following table is provided for general guidance only; always refer to the exact parameters of your modules to make sure they are within the allowed range.

The above parameter values are calculated under standard test conditions (STC – Standard Test Conditions): solar irradiance 1000W/m2, module temperature 25°C, air mass 1.5.

2. PV array maximum power
   The MPPT controller has a current/power-limiting function. During the charging process, when the solar panel current or power exceeds the rated charging current or power, the controller will automatically limit the charging to the rated level. This protects the charging circuits of the controller and reduces the risk of damage caused by connection of over-specification PV modules. The current/power-limiting function operates as follows:

Condition 1:
Actual charging power of PV array ≤ Rated charging power of controller
Condition 2:
Actual charging current of PV array ≤ Rated charging current of controller When the controller operates under “Condition 1” or “Condition 2”, it will carry out the charging as per the actual current or power; at this time, the controller can work at the maximum power point of PV array.
Condition 3:
Actual charging power of PV array > Rated charging power of controller
Condition 4:
Actual charging current of PV array > Rated charging current of controller When the controller operates under “Condition 3” or “Condition 4”, it will carry out the charging as per the rated current or power.
WARNING:
When the power of the PV array is greater than the rated charging power, and the maximum open-circuit voltage of PV array is more than 150V for Tracer15AN or 200V for Tracer20AN (at the lowest environmental temperature), the controller may be damaged.
If the PV array power is higher than the nominal rated power of the controller and the controller has to limit the PV power, the battery charging time will be extended accordingly.
WARNING:
The controller will be damaged if a PV array is connected to the controller PV terminals with the right or reverse polarity and the max PV power is more than 1.5 times the rated controller power!
When the PV array is connected to the controller with either the correct or reverse polarity, the maximum PV array power must NOT exceed 1.5 times the nominal (rated) controller power. Please refer to the table below:

1.  At minimum operating environment temperature
2. At 25°C environment temperature

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 based on the maximum current (Isc) of PV array. Please refer to the value of Isc in the PV module specification. When PV modules are connected in series, the Isc is equal to one PV modules Isc. When PV modules are connected in parallel, the Isc is equal to the sum of the Isc of all the PV modules. The Isc of the PV array must not exceed the controller’s maximum PV input current. Please refer to the table as below:
NOTE:
All PV modules in a given array are assumed to be identical. NOTE: All PV modules in a given array are assumed to be identical.

• These are the maximum wire sizes that will fit the controller terminals.

CAUTION:
When the PV modules connect in series, the open circuit voltage of the PV array must not exceed 138V at 25°C environment temperature for Tracer15AN or 180V for Tracer20AN.
Battery Wire Size
The battery wire size must conform to the rated current, the reference size as below:

CAUTION:
The wire size is only for reference. If there is a long distance between the PV array and the controller or between the controller and the battery, larger wires should be used to reduce the voltage drop and improve performance.

• The battery cable size recommendations assume that the charge controller is the only device connected to this cable (no inverter connected to the same cable etc).

Relay Instruction

Utility/Generator Relay and Load Parameter
Rated Value: 5A/30VDC
Maximum Value: 0.5A/60VDC

1. Control the utility/generator ON/OFF via the utility/generator relay
   Utility/Generator start-up Voltage (VON)=Under Voltage Warning Voltage (VUVW)
   Utility/Generator stop Voltage (VOFF)= Under Voltage Warning Recover Voltage (VUVWR)
   Low Voltage Disconnect Voltage (VLVD)
   Battery Voltage (VBAT)

   • Utility/Generator activates: VBAT < VON
   • Utility/Generator deactivates: VBAT > VOFF
     CAUTION:
     The VON and VOFF can only be set via the PC software, for the Battery Control Voltage Parameters refer to chapter 3.4 Settings.

2. Control the first and second load disconnection
   The controller can disconnect different classes of loads in two stages, leaving the most important loads connected for longer to allow them to discharge the batteries deeper. In such case, both generator control relay output and load control relay output of the controller will need to be used:

• The generator control relay will disconnect the first class of loads earlier and reconnect later;
• The load control relay will disconnect the second class of loads later (allowing it to discharge the battery deeper) and reconnect earlier.
  Parameters to note: Battery Voltage (VBAT); Under Voltage Warning Voltage (VUVW); Under Voltage Warning Recover Voltage (VUVWR); Low Voltage Disconnect Voltage (VLVD); Low Voltage Reconnect Voltage (VLVR)

First class of loads disconnection (Utility/Generator Relay, normally closed contact):
VBAT≤VUVW: The Utility/Generator Relay normally closed contact will turn OFF the first load
VBAT≥VUVWR: The Utility/Generator Relay normally closed contact will turn ON the first load
Second class of loads disconnection (Load Relay)：
VBAT≤VLVD: The Load Relay will turn OFF the second load
VBAT≥VLVR: The Load Relay will turn ON the second load
CAUTION:
For the Battery Control Voltage Parameters refer to the chapter 3.4 Settings.
WARNING:
When the system power is off, the utility/generator relay normally closed contact is closed, please check that this will not cause problems for your setup.
Refer to the below the diagram:

 Mounting

WARNING:
Do not reverse the polarity of the batteries. Reverse polarity will damage the charge controller permanently. Damage caused by reverse polarity is not covered by warranty.

•  Risk of explosion! Never install the controller in a sealed enclosure with flooded batteries! Do not install in a confined area where battery gas can accumulate.
• Risk of electric shock! The solar array high voltage can cause serious shock or injury. Make use of fuses/breakers for isolation or cover the entire solar array prior to performing any work on the solar charge controller.

CAUTION：
The controller requires at least 150mm of clearance above and below for proper air flow. Ventilation is required if mounted in an enclosure.

Installation steps:

Determine the installation location and heat-dissipation space
The controller should be installed in a place that allows sufficient air flow through the heat sink of the controller and a minimum clearance of 150 mm from the upper and lower edges of the controller to ensure natural thermal convection. Please see the figure below. Fix the controller firmly in place to a rigid surface using the mounting holes. Non-combustible surface is recommended.
CAUTION:
If the controller is to be installed in an enclosed box, it is important to ensure reliable heat dissipation through the box and ventilation.

Remove the terminal protective cover

Connect the battery❶(Left) then the PV❷(Right)

NOTE:
Disconnect the system in the reverse order, PV first, then battery second.
WARNING:
Do not reverse the polarity of the batteries. Reverse polarity will damage the charge controller permanently. Damage caused by reverse polarity is not covered by warranty.
CAUTION:
While wiring the controller do not turn on the breaker or fuse and make sure that the leads of “+” and “-” poles are connected correctly.

• A fuse or an over-current circuit breaker with the current rating 1.25 to 2 times the rated current of the controller must be installed on the battery cable with a distance from the battery not greater than 150 mm.
• If an inverter is to be connected to the system, connect the inverter directly to the battery.

One controller:Multiple controllers: Grounding
The PTR Tracer AN series is a common-negative controller. If any negative terminal is grounded, then both negative terminals of PV and battery will be grounded simultaneously. Grounding these terminals is not necessary for typical operation, but the grounding terminal on the case must be grounded. This shields the internal components from electromagnetic interference and reduces risk of electric shock to the user due to the electrification of the shell.
CAUTION:
For common-negative applications, such as vehicles or boats, it is recommended to use a common-negative controller. If the common-negative system includes some common-positive equipment where the positive electrode is grounded, the controller may be damaged.
Connect accessories

•  Connect the remote temperature sensor cable (Model: TEMP_VS) Connect the remote temperature sensor cable to the interface ❽and place the other end close to or on the battery.

CAUTION:
If the remote temperature sensor is not connected to the controller, the default setting for battery charging or discharging temperature is 25°C without temperature compensation.

• Connect the remote battery voltage measurement cable

Connect the remote battery voltage measurement cable to the interface ⓫ and connect the other end to the battery terminals.

•  Connect the accessories for RS485 communication (refer to the accessories list).

Power on the controller
Turn on the battery fuse/circuit breaker to power on the controller. Check that the unit powers on and the fault indicator does not stay lit.
CAUTION:
If the controller is not operating properly or the battery indicator on the controller shows an abnormality, please refer to 4.2 “Troubleshooting”.
Connect the solar array
Turn on the solar circuit breaker to connect the solar panels to the controller. If the solar panels are exposed to light, check that the controller started charging the battery.
Note that the disconnection should follow the reverse order: disconnect the solar array first, then disconnect the battery from the controller.

 Protections, Troubleshooting & Maintenance

 Protections

WARNING:
Do not reverse the polarity of the batteries. Reverse polarity will damage the charge controller permanently. Damage caused by reverse polarity is not covered by warranty.

PV Over Current/power| When the charging current or power of the PV array exceeds the controller’s rated current or power, it will charge at the rated current or power.
NOTE: When the PV modules are in series, ensure that the open- circuit voltage of the PV array does not exceed 138V for Tracer15AN or 180V for Tracer20AN, otherwise the controller may be damaged.
---|---
PV Short- Circuit| When not in PV charging state , the controller will not be damaged in case of a short-circuit in the PV array.
PV Reverse Polarity| When the polarity of the PV array is reversed, the controller will not be damaged and can continue to operate normally after the polarity is corrected.
NOTE: This will not protect against PV arrays with rated power more than 1.5x the nominal power
Night Reverse Charging| The controller prevents the battery from discharging through the PV array at night.
Battery Over Voltage| When the battery voltage reaches the over voltage disconnect voltage, it will automatically stop battery charging to prevent battery damage caused by over-charging.
Battery Over Discharge| When the battery voltage reaches the low voltage disconnect voltage, it will automatically stop battery discharging to prevent battery damage caused by over-discharging (any loads managed by the controller relay will be disconnected).
NOTE: loads connected to the battery directly will not be affected and may continue to discharge the battery.
Battery Overheating| The controller can detect the battery temperature through an external temperature sensor (optional). The controller stops working when its temperature exceeds 65°C and resumes when the battery temperature is below 55°C.
Controller Overheating*| The controller is able to detect the temperature of its internal components. The controller stops working when the temperature exceeds 85°C and resumes when its temperature is below 75°C.
---|---
TVS High Voltage Transients| The internal circuitry of the controller includes Transient Voltage Suppressors (TVS) which provide limited protection against high- voltage surge pulses. If the controller is to be used in an area with frequent lightning strikes, it is recommended to install an external surge arrester.

• When the internal temperature is 81°C, the overheating protection function will reduce the charging power by 5%,10%,20%,40% for each 1°C increase. If the internal temperature is greater than 85°C, the controller will stop charging.

Example of the controller overheating protection for PTR10420AN in a 48V system:

Troubleshooting

battery wire connections are correct and tight
** Wire connection is correct, LCD display is still off| Battery voltage is lower than 8V| Please check the voltage of battery. At least 8V voltage is required to start the controller.
The LCD display is on, the solar panel is in good light but it is not charging| Incorrect polarity of the solar PV connection or low PV voltage| ** Check the PV connection polarity and the voltage. The voltage from the PV panels should be higher than the battery charging voltage.
