Maintenance and repair
Before any repair work, turn OFF the AC circuit
breaker between the inverter and electrical grid
first, then turn OFF the DC switch.
After turning OFF the AC circuit breaker and DC
switch, wait for 5 minutes at least before carrying
out any maintenance or repair work.
Danger
Inverter should work again after removing any
faults.If you need any repair work, please contact
with the local authorized service center.
Can’t open the internal components of inverter
without authorized.Shenzhen SOFARSOLAR Co. ,
Ltd.Does not take any responsibility for the losses
from that.
Attention
EMC / noise level of inverter
Electromagnetic compatibility (EMC) refers to that one electrical
equipment functions in a given electromagnetic environment without
any trouble or error, and impose no unacceptable effect upon the
environment.Therefore, EMC represents the quality characters of an
electrical equipment. The inherent noise-immune character: immunity
to internal electrical noise. External noise immunity: immunity to
electromagnetic noise of external system. Noise emission level:
influence of electromagnetic emission upon environment.
