Output short circuit protection   yes   Before starting, when the output short circuit is detected, the output will not start. After the fault is removed, normal operation will be restored. During operation, when the output is short-circuited, the output is turned off
Output reverse connection protection   yes    
Communication failure protection yes When the BMS command is not received for 5 seconds, the CAN communication fault is reported.
Over temperature protection >75 °C If the water temperature exceeds 75°C, the output power will be derated. When the water temperature is ≤75℃, the charger returns to normal power. When ≤75℃, the charger returns to normal power.
