correctly
1. Check the ventilation of
installation environment
2. Avoid direct sunlight
Check if the ambient
temperature is below normal
working temperature of
inverters and increase
ambient temperature
1. Check if the input voltage
exceeds the inverter's upper
limit of input voltage.
2. Decrease solar panel
quantity in series
1. Wait for the inverter to
recovery
2. If the impedance of AC
cable is too small, replace it
with a larger size cable
3. Adjust the protection value
limit as permitted by the grid
