1.If the alarm occurs accidentally, the inverter can generate power, which may
cause the power grid to cause the inverter to automatically recover. No extra
B2-Leakage action is needed.
current 2.If the alarm occurs frequently, and is accompanied by an insulation impedance
abnormal alarm. Check the abnormal alarm of the insulation.
3. If the alarm continues, the equipment cannot generate electricity, please
contact the customer service report repair
1.If occurs when the light is weak(such as the early morning or evening, and the
extreme weather of rain and dust storms), the component voltage is lower than

relay whether the live line and zero line of the contact connection is reversed; the
abnormal three-phase inverter check the live line to zero line and the voltage of the
live line to the ground. If the grid side is normal, please contact the customer
service report repair.
1. If the alarm occurs occasionally, the inverter can be automatically restored,
no action required.
C5-Inverter over 2. If the alarm occurs repeatedly, pls. check the installation site for direct
temperature sunlight, good ventilation, and high ambient temperature (Such as installed
on the parapet). If the ambient temperature is lower than 45° C and the heat
dissipation is good, contact the customer service center.
