Check if the fan is not turning or blocked by foreign object.
Heat sink over temperature
protection
When the temperature of the device is lower than the recovery temperature, normal
charge and discharge control is resumed.
Bypass overload protection, inverter
overload protection
① Reduce the use of power equipment; ② Restart the unit to resume load output.
Inverter short circuit protection
① Check the load connection carefully and clear the short-circuit fault points; ②
Re-power up to resume load output.
Use a multi-meter to check if the PV input voltage exceeds the maximum allowable
input voltage rated.
Check if the battery is not connected or if the battery circuit breaker is not closed.
