Wiring
Connection sequence
- Connect components to the controller in the sequence ① > ② > ③ as shown above and pay much attention to the “+” and “-.” Please don’t insert the fast-acting fuse or turn on the breaker during the installation. When disconnecting the system, the order will be reserved.
- After powering the controller, the battery LED indicator on the controller shall flash green. If it’s not green, please refer to chapter 10, Troubleshooting.
- Connect a fast-acting fuse in series through battery positive (+) in the circuit. The battery fast-acting fuse must be 1.25 to 2 times the rated current. The installed distance is within 150mm.
Load self-test function
The load is automatically turned ON after powering on the controller for 10s. After the load keeps ON status for 10s, the controller restores to the set working mode

Protection
-
PV Over Current
The controller will limit the battery charging current to the Maximum Battery Current rating. Therefore an oversized solar array will not operate at peak power. -
PV Short Circuit
When PV short circuit is powered on or the PV input is a short circuit on low- power, the controller will stop charging. Clear it to resume regular operation.
| The controller may be damaged when the PV input is a short circuit on a
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 PV’s open-circuit voltage is lower than 85V(This requirement is only for Tracer26/39/5210BP).
| The controller will be damaged when the PV array straight polarity and the
PV array’s actual operating power is 1.5 times greater than the rated charge
power!
---|---
- Battery Reverse Polarity
When the PV is not connecting or connecting reversed, complete protection against reverse battery polarity, correct the wire connection to resume regular operation.
| The controller will be damaged when the PV connection is correct, and the
battery connection reversed!

-
Battery Over Voltage
When the battery voltage reaches the set point of Over Voltage Disconnect Voltage, the controller will stop charging the battery to protect the battery from being overcharged to break down. -
Battery Over Discharge
When the battery voltage reaches the 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 ºC. -
Lithium battery Low Temperature
The temperature sensor is less than the low-temperature value, and the Lithium battery stops charging/discharging. It is higher than the low-temperature value, and the Lithium battery starts 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 by reducing the load and restarting the controller. -
Load Short Circuit The load will be switched off when the load short circuit (≥4 times rated current) happens.
The controller will automatically attempt to reconnect the load 5 times. Suppose short circuit protection still exists after the controller’s 5 times attempts. In that case, the user has to clear the short circuit, restart the controller or wait for one night-day cycle (night time>3 hours). -
Temperature sensor break down Suppose the temperature sensor is short-circuited or damaged. In that case, the controller shall be charging or discharging at the default temperature of 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
| Faults | Possible reasons | 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 may be 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 the
battery voltage is higher than OVD, and disconnect the PV
Battery LED indicator red| Battery over-discharge d| When the battery voltage
is restored to or above the 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| Load Overload ①| ①Please reduce the number of electric
equipment.
②Restart the controller.
③wait for one night-day cycle (night time>3 hours).
Load Short ①Circuit| 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 has 5 times auto- recovery output function, which each time delay respectively 5s, 10s, 15s, 20s, 25s.
