•

Restart the inverter only after removing the fault that impairs safety
performance.

•

As the inverter contains no component parts that can be maintained, never
arbitrarily replace any internal components.

•

For

any

maintenance

need,

please

contact

SUNGROW.

Otherwise,

SUNGROW shall not be held liable for any damage caused.

System

clean

Check the temperature and dust of the

inverter. Clean the inverter enclosure if

necessary.

Check if the air inlet and outlet are normal.

Clean the air inlet and outlet, if necessary.

Six months to a year (-
