3.1 General Installation Notes

Read through the entire installation section first before beginning installation.

Be very careful when working with batteries. Wear eye protection. Have fresh water available to wash and clean any contact with battery acid.

Uses insulated tools and avoid placing metal objects near the batteries.

Explosive battery gasses may be present during charging. Be certain there is sufficient ventilation to release the gasses.

Avoid direct sunlight and do not install in locations where water can enter the controller.

Loose power connections and/or corroded wires may result in resistive connections that 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.

Use with Gel, Sealed or Flooded batteries only.

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.

Select the system cables according to 3A/mm

2

current density.

3.2 Mounting

NOTE: When mounting the Tracer, ensure free air through the controller heat sink fins. There should be at least 150mm of clearance above and below the controller to allow for cooling. If mounted in an enclosure, ventilation is highly

recommended.

WARNING: Risk of explosion! Never install the Tracer in a sealed enclose with flooded batteries! Do not install in a confined area where battery gas can accumulate.

Step 1: Choose Mounting Location

Locate the Tracer on a vertical surface protected from direct sun, high temperature, and water.

Step 2: Check for Clearance

Place the Tracer in the location where it will be mounted. Verify that there is sufficient room to run wires and that there is sufficient room above and below the controller for air flow.

Step 3: Mark Holes

Use a pencil or pen to mark the four (4) mounting hole locations on the mounting surface.

5

Step 4: Drill Holes

Remove the controller and drill four sizeable holes in the marked locations.

Step 5: Secure Controller

Place the controller on the surface and align the mounting holes with the drilled holes in step 4. Secure the controller in place using the mounting screws.

3.3 Wiring

NOTE: A recommended connection order has been provided for maximum safety during installation.

NOTE: The Tracer is a negative ground controller. Any negative connection of solar module, battery or load can be earth grounded as required. Grounding is recommended.

CAUTION: Don’t connect the loads with surge power exceeding the ratings of the controller.

CAUTION: For mobile applications, be sure to secure all wiring. Use cable clamps to prevent cables from swaying when the vehicle is in motion. Unsecured cables create loose and resistive connections which may lead to excessive heating

and/or fire.

Step 1: Battery Wiring

WARNING: Risk of explosion or fire! Never short circuit battery positive (+) and negative (-) or cables

Fuse

Battery

Figure 3-1 Battery wiring

6

Before connecting the battery, measure the battery voltage. It must be over 9V to power the controller. For 24V, the voltage must be greater than 18V to properly detect a 24V battery. The 12/24V battery detection is automatic and the check is only performed at start-up.

Wire an in-line fuse holder no more than 150mm from the battery positive terminal. Do not insert a fuse at this time. Confirm the connection correct and then turn on the power.

Step 2: Load Wiring

The Tracer load output can connect DC electronic devices of which rated voltage is same as battery’s. Tracer will provide battery voltage to the loads. See Section 4.4

Setting Operation for more details about the load control.

Fuse

Load

Figure 3-2 Load wiring

Connect load positive (+) and negative (-) to the Tracer load output as shown in figure 3-2. The load terminals may exist voltage, connect carefully to avoid short circuit.

An in-line fuse holder should be wired in series in the load positive (+) or negative (-) wire as shown. Do not insert a fuse at this time. Confirm the connection correct and then turn on the power.

If wiring the load connection to a load distribution panel, each load circuit should be fused separately. The total load draw should not exceed the 20A load rating.

Step 3

Solar Module Wiring

WARNING: Risk of electric shock! Exercise caution when handling solar wiring.

The solar module(s) high voltage output can cause severe shock or injury. Cover the solar module(s) from the sun before installing solar wiring.

7

The Tracer can accept 12V, 24V nominal off-grid solar module arrays. Grid –tie solar module(s) may be used if the open circuit voltage does not exceed the maximum solar input rating. The solar module(s) nominal voltage must be equal to or greater than the nominal battery voltage.

Solar Module

Figure3-3 Solar Module wiring

Step 4: Accessories (option)

Install Remote Meter (purchased separately) if required. Refer to the instructions provided for detailed installation procedures.

Step 5: Confirm Wiring

Double-check the wiring in step1 through 4. Confirm correct polarity at each connection. Verify that all six power terminals are tightened.

Step 6: Confirm Power-up

When battery power is applied and the Tracer powers up, the battery led indicator will be green.

If the Tracer does not power up or battery status LEDs error exists, refer to

Section 5 Troubleshooting

4 Operation

4.1 MPPT Technology

The Tracer utilizes Maximum Power Point Tracking technology to extract maximum power from the solar module (s). The tracking algorithm is fully automatic and does not require user adjustment, Tracer technology will track the array

maximum power point voltage

(Vmp) as it varies with weather conditions, ensuring that maximum power is harvested from the array through the course of the day.

In many cases, Tracer MPPT technology will ―boost‖ the solar charge current.

For example, a system may have 8 Amps of solar current flowing into the Tracer and

10 Amps of charge current flowing out to the battery. The Tracer does not create current! Rest assured that the power into the Tracer is the same as the power out of the

Tracer. Since power is the product of voltage and current (Volts×Amps), the following is true

*

:

(1) Power Into the Tracer =Power Out of the Tracer

(2) Volts In×Amps In=Volts Out×Amps Out

*

Assuming 100% efficiency. Actually, the losses in wiring and conversion exist.

If the solar module’s Vmp is greater than the battery voltage, it follows that the battery current must be proportionally greater than the solar input current so that input and output power are balanced. The greater the difference between the maximum power voltage and battery voltage, the greater the current boost. Current boost can be substantial in systems where the solar array is of a higher nominal voltage than the battery.

·

An Advantage Over Traditional Controllers

Traditional controllers connect the solar module directly to the battery when recharging. This requires that the solar module operate in a voltage range that is below the module’s Vmp. In a 12V system for example, the battery voltage may range from

11-15Vdc but the module’s Vmp is typically around 16 or 17V.

Figure 4-1 shows a typical current VS. voltage output curve for a nominal 12V off-grid module.

Figure 4-1 Nominal 12V Solar Module I-V curve and output power graph

The array Vmp is the voltage where the product of current and voltage

(Amps×Volts) is greatest, which falls on the ―knee‖ of the solar module I-V curve as shown in Figure4-1. Because Traditional controllers do not operate at the Vmp of the solar modules(s), energy is wasted that could otherwise be used to charge the battery and power system loads. The greater the difference between battery voltage and the

Vmp of the module, the more energy is wasted.

Tracer MPPT technology will always operate at the Vmp resulting in less wasted energy compared to traditional controllers.

·

Conditions That Limits the Effectiveness of MPPT

The Vmp of a solar module decreases as the temperature of the module increases.

In very hot weather, the Vmp may be close or even less than battery voltage. In this situation, there will be very little or no MPPT gain compared to traditional controllers.

However, systems with modules of higher nominal voltage than the battery bank will always have an array Vmp greater than battery voltage. Additionally, the savings in wiring due to reduced solar current make MPPT worthwhile even in hot climates.

4.2 Battery Charging Information

Four Charging Stage

The Tracer has a 4-stage battery charging algorithm for rapid, efficient, and safe battery charging.

10

Figure 4-2

Tracer

MPPT charging algorithm

In this stage, the battery voltage has not yet reached boost voltage and 100% of available solar power is used to recharge the battery.

When the battery has recharged to the Boost voltage setpoint, constant-voltage regulation is used to prevent heating and excessive battery gassing. The Boost stage remains 120 minutes and then goes to Float Charge.

Every time when the controller is powered on, if it detects neither over discharged nor overvoltage, the charging will enter into boost charging stage.

After the Boost voltage stage, Tracer will reduce the battery voltage to Float voltage setpoint. When the battery is fully recharged, there will be no more chemical reactions and all the charge current transmits into heat and gas at this time. Then the

Tracer reduces the voltage to the floating stage, charging with a smaller voltage and current. It will reduce the temperature of battery and prevent the gassing, also 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 stage, loads can continue to draw power from the battery. In the event that the system load(s) exceed the solar charge current, the controller will no longer be able to maintain the battery at the Float setpoint. Should the battery voltage remains below the boost reconnect charging voltage, the controller will exit Float stage and return to Bulk charging.

WARNING: Risk of explosion!

Equalizing flooded battery can produce explosive gases, so well ventilation of battery box is necessary.

NOTE: Equipment damage!

Equalization may increase battery voltage to the level damaging to sensitive

DC loads. Ensure that all load allowable input voltages are greater than the

equalizing charging set point voltage.

NOTE: 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.

Certain types of batteries benefit from periodic equalizing charge, which can stir the electrolyte, balance battery voltage and complete chemical reaction. Equalizing charge increases the battery voltage, higher than the standard complement voltage, which gasifies the battery electrolyte.

If it detects that the battery is being over discharged, the solar controller will automatically turn the battery to equalization charging stage, and the equalization charging will be 120mins.

Equalizing charge and boost charge are not carried out constantly in a full charge process to avoid too much gas precipitation or overheating of battery.
