Safety Information

• Read all of the instructions in the manual before installation.
• DONOT disassemble or attempt to repair the controller.
• Install external fuse or breaker as required.
• Do disconnect the solar module and fuse/ breakers near to battery before installing or moving the controller.
•  Power connections must remain tight to avoid excessive heating from a loose connection.
• Only charge batteries that comply with the parameters of controller.
• Battery connection may be wired to one battery or a bank of batteries.
• Risk of electric shock, the PV and load can produce high voltages when the controller is working.

Product Features

1. The temperature sensor short-circuited or damaged, the controller will be charging or discharging at the default temperature 25 ºC.
2. The port can provide the DC power supply of 5VDC/150mA and have the short circuit function.

NOTE: When the RS485 communication port is not working, the waterproof cap must be installed to prevent water getting in.

Wiring

Connection Order

1. Connect components to the charge controller in the sequence as shown above and pay much attention to the “+” and “-”.Please don’t insert the fuse or turn on the breaker during the installation. When disconnecting the system, the order will be reserved.
2. After power on the controller, check the battery LED indicator on the controller, it will be green. If it’s not green, please refer to chapter 10.
3. Connect a fuse in series through battery positive (+) in the circuit and the battery circuit fuse must be 1.25 to 2 times to the rated current. The installed distance is within 150mm.

Load self-test function
The load is ON when the controller power on 10s. After 10s it will restore to set working mode.

LED Indicators

voltage(irradiance) from PV, no charging
Green| OFF| No PV voltage(night time) or PV connection problem
Green| Slowly Flashing(1Hz)| In charging
Green| Fast Flashing(4Hz)| PV Over voltage
| Green| On Solid| Normal
Green| Slowly Flashing(1Hz)| Full
Green| Fast Flashing(4Hz)| Over voltage
Orange| On Solid| Under voltage
Red| On Solid| Over discharged
Red| Fast Flashing(4Hz)| Battery Overheating Low temperature
Charging(green) and battery indicator(orange)flashing simultaneously| System voltage error※

※When the battery type is Lithium Battery the controller do not recognize the system voltage automatically.

Load Working Mode

1. Manual Mode(Default ON)
2. Light ON/OFF
3. Light ON+ Timer
4. Real-time Control
   Control the load ON/OFF time through setting real-time clock.

NOTE: In the mode of Light ON/OFF and Light ON/Timer, the Load isturned on after 10Min. delay.

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 is powered on or PV input is short circuit on low-power, the controller will stop charging. Clear it to resume normal operation.
  WARNING: The controller may be damaged, when PV input is short circuit on high-power.

• PV Reverse Polarity
  The PV can be reversely connected with a controller when:
  Only the PV is connected with the controller;
  The battery is positively connected, and the open-circuit voltage of the PV is lower than 85V(This requirement is only for Tracer26/39/5210BP).
  WARNING: Controller will be damaged when the PV array straight polarity and the actual operation power of the PV array is 1.5 times greater than the rated charge power!

• Battery Reverse Polarity
  When the PV is not connecting or connecting reversed, fully protection against battery reverse polarity, correct the wire connection to resume normal operation.
  WARNING: Controller will be damaged when the PV connection is correct and battery connection reversed!

• Battery Over Voltage
  When the battery voltage reaches to the set point of Over Voltage Disconnect Voltage, the controller will stop charging the battery to protect the battery from being over
  charged to break down.

• Battery Over Discharge
  When the battery voltage reaches to the set point of Low Voltage Disconnect Voltage, the controller will stop discharging the battery to protect the battery from being over discharged to break down.

• Battery Overheating
  The controller detects the environment temperature through the external temperature sensor. If the environment temperature exceeds 65 ºC, the controller will automatically start the overheating protection to stop working, and recover below 55 º C .

• Lithium battery Low Temperature
  The temperature sensor is less than the low temperature value, Lithium battery stop charging/discharging. It is higher than the low temperature value, Lithium battery start charging/discharging.

• 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
  Load will be switched off when load short circuit (≥4 times rated current) happens. Controller will automatically attempt to reconnect load for 5 times. If short circuit protection still exist after controller’s 5 times attempts, user have to clear short circuit ,then restart the controller or wait for one night-day cycle (night time>3 hours).

• Temperature sensor break down
  If the temperature sensor short-circuited or damaged, the controller will be charging or discharging at the default temperature 25 ºC to prevent the battery damaged from
  overcharging or over discharged. High Voltage Transients
  The controller is protected against small high voltage transients. In lightning prone areas, additional external suppression is recommended.

Troubleshooting

LED Charging indicator turn off during daytime when sunshine falls on PV modules properly| PV array disconnection| Confirm that PV and battery wire connections are correct and tight
No LED indicator| Battery voltage maybe less than 8.5V| Measure battery voltage with the multi-meter. Min.8.5V can start up the controller
Battery LED indicator green fast Flashing| Battery over voltage| Check if battery voltage is higher than OVD, and  disconnect the PV
Battery LED indicator red| Battery over discharged| When the battery voltage is restored to or above LVR point (low voltage reconnect voltage), the load will recover
Battery LED indicator red flashing| Battery Overheating| The controller will automatically turn the system off. But while the temperature decline to be below 50
ºC, the controller will resume.
Load is not output| ① Load Overload| ①Please reduce the number of electric equipments.
②Restart the controller.
③wait for one night-day cycle (night time>3 hours).
① Load Short Circuit| ①Check carefully loads connection, clear the fault.
②Restart the controller.
③wait for one night-day cycle (night time>3 hours).

① When it is overload or short circuit, the load have 5 times auto- recovery output function, which each times delay respectively 5s, 10s, 15s, 20s, 25s.
This warranty does not apply under the following conditions:

• Damage from improper use or use in an unsuitable
• PV or load current, voltage or power exceeding the rated value of
• The controller is working temperature exceed the limit working environment
• User disassembly or attempted repair the controller without
