※MT50 does not support the relevant parameters of the lithium battery.
Note: Only the Tracer-CPN series support the external EPEVER BLE module, the
Tracer-CPN (BLE) series are already designed with a built-in Bluetooth module.
7. Protection
 PV Over Current
The controller will limit the battery charging current to the rated charge current.
Therefore an oversized solar array may not work at peak power.
 PV Short Circuit
The controller will stop charging when the PV input is short-circuited or the
short-circuit occurs at the low-power charging. Clear faults to resume work.
WARNING
The controller may be damaged when the PV input is short-circuited
on a high-power.
 PV Reverse Polarity
The PV can be reversely connected with a controller when:
①Only the PV is connected to the controller. ②The battery is correct connected,
and the PV open-circuit voltage is lower than 85V.
WARNING
The controller will be damaged when the PV array is reversely
connected, and the PV array's actual power exceeds 1.5 times the
rated charge power!
 Battery Reverse Polarity
The battery can be reversely connected when the PV is disconnected or reversely
connected. Correct the wire connection to resume work.
WARNING
The controller will be damaged when the PV connection is correct
and the battery connection is reversed!
 Battery Over Voltage
When the battery voltage exceeds the Over Voltage Disconnect Voltage, the
controller will stop charging the battery to protect the battery from being overcharged.
 Battery Over Discharge
When the battery voltage is lower than the Low Voltage Disconnect Voltage, the
controller will stop discharging the battery to protect the battery from being
over-discharged.
 Battery Overheating
The controller detects the environment temperature by the external temperature
sensor. If the environment temperature exceeds 65ºC, the controller will stop working
and recover below 55º C .
 Lithium battery Low Temperature
When the battery temperature is lower than the low-temperature protection value, the
Lithium battery charging/discharging is stopped. It resumes work when the battery
temperature exceeds the low-temperature protection value.
 Load Overload
If the load current exceeds 1.05 times the rated load current, the controller will
disconnect the load after a delay time. Overloading must be cleared by reducing the
load and restarting the controller.
 Load Short Circuit
The load will be switched off when the short circuit (≥4 times rated load current)
happens. The controller will automatically attempt to reconnect the load five times.
Suppose short circuit protection still exists after the fifth attempt. 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 breakdown
When the temperature sensor is short-circuited or damaged, the controller will charge
or discharge at 25°C by default to avoid damage to the battery caused by overcharge
or over-discharge.
 High-voltage Transients
The controller is protected against small high-voltage transients. In lightning-prone
areas, additional external arrester is recommended.

①
①Check carefully the loads'
connection and clear the fault.
②Restart the controller.
③wait for one night-day cycle (night

①When the load is overloaded or short-circuited, the load will automatically
restore output five times, respectively, delaying 5S, 10S, 15S, 20S, and 25S.
10. Disclaimer
This warranty does not apply to the following conditions:
 Damage from improper use or use in an unsuitable environment.
 PV or load current, voltage, or power exceeds the rated value of the controller.
 The actual working temperature exceeds the limited working environment
temperature.
 The user disassembly or attempted to repair the controller without permission.
 The controller is damaged due to natural elements such as lighting.
 The controller is damaged during transportation and shipment.
