Table 5-1 Error message prompt
CODE DESCRIPTION
W00-1 Alarm due to low speed of fan group 1.
W01-1 Alarm due to low speed of fan group 2.
W02-1 Alarm due to low speed of fan group 3.
W03-1 Zero power alarm is normal when light is weak and
power is very small.
W16-1 Clock chip failure.
W21-1 Alarm due to triggering action of lightning protector.

SOLUTION
(1) Confirm whether the safety standards selected for the
machine are in compliance with local grid requirements.
(2) Inspect whether the AC output terminal is connected
reliably and measure whether the voltage is normal with
a multimeter.
(3) Disconnect the PV input, restart the machine, and see if
the machine can return to normal.
(4) Contact ZIGOR if the fault still exists.
(1) Please check the setting of input mode.
(2) Disconnect PV input and restart the inverter and check
whether fault still exists.
(3) Contact ZIGOR if the fault still exists.
(1) Please check the setting of input mode.
(2) Confirm the bus-bar voltage imbalance through the LCD
display panel. Restart the machine several times every
few minutes to see if the machine can return to normal.
(3) Contact ZIGOR if the fault still exists.
