function.
CAUTION
When the RS485 communication port is not working, the waterproof
cap must be installed to prevent water from getting in.
4. Wiring
Connection sequence
1) Connect components to the controller in the sequence ①> ②> ③as 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 powering the controller, the battery LED indicator on the controller shall flash
green. If it's not green, please refer to chapter 10, Troubleshooting.
3) Connect a fuse in series through battery positive (+) in the circuit. The battery circuit
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.

8. 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.
WARNING
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).
WARNING
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.
WARNING
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.
