Phenomenon and Possible Cause
Phenomenon and
Possible Cause
32 Bus Volt Bal.Err M
1)The Voltage of the BUS middle point
is beyond half of the BUS voltage.
2)If random, a possible cause is the
quick
variation of grid voltage.
If the error is still active, please
contact the local agent or SAJ
Service line.
33 Bus Volt High M
1)The open-circuit voltage of the PV
generator is higher than the maximum
DC input voltage of the inverter.
2)Sudden DC surge.
If the error is still active, please
contact the local agent or SAJ
Service line.
34 Bus Volt Low M
1)Boost MOSFET/IGBT damaged or the
PV string configuration is not correct.
2)Happens during Sunset. Can reproduce
daily.
If the error is still active, please
contact the local agent or SAJ
Service line.
35 L1 Current High M
The output current is beyond the firmware
limited value.
If random, a possible cause is the quick
variation of grid voltage.
Repetitive error means firmware failure
(Iac sensor).

45 Fan1 Error M
Fan locked or damaged.
Check the fans under the case
of the inverter. If fans are good,
please clean them. If the error
is still active, please contact the
local agent or SAJ Service line.
