·Load Short Circuit
Fully protected against load wiring short-circuit（≥2 times rated
discharge current）. After one automatic load reconnect attempt, the
fault must be cleared by restarting the controller or pressing the switch
button.
·PV Reverse Polarity
Fully protection against PV reverse polarity, no damage to the
controller will result. Correct the miswire to resume normal operation.
·Battery Reverse Polarity
Fully protection against battery reverse polarity, no damage to the
controller will result. Correct the miswire to resume normal operation.
·Battery working voltage error
If battery voltage does not match controller working voltage, controller
will stop working. After correcting the voltage, the failure can be
eliminated through pushing load button.
·Damaged Temperature Sensor
If the temperature sensor short-circuited or damaged, the controller
will be charging or discharging at the default temperature 25℃ to
prevent the battery damaged from overcharging or over discharged.
·Overheating Protection
If the temperature of the controller heat sink exceeds 85C, the
controller will automatically start the overheating protection and stop
the charging and discharging.
When the temperature is below 75, the
controller will resume to work.
·High Voltage Transients
PV
is protected against smaller high voltage surge. In lightning prone
areas, additional external suppression is recommended.
Note: The controller has daily automatic fault recovery function
which will reduce the manual operation and can intelligently
eliminate the fault caused by non-actual hardware failure.
