507
Error alarm of DO power
settings.
Modify the DO control power
according to the load power. Refer
to “Optimized Control” in the user
manual.
509
Clock reset fault.
Manually reset the clock or
synchronize the clock with the
network time. This will clear the
fault.
510
PV over-voltage fault.
1. Check whether the
configuration of the PV array
exceeds the permissible range of
the inverter.
2. Wait a moment for inverter
recovery or restart the system.
513
Fan1 abnormal speed warning.
1. Check if the fan is blocked.
2. Restart the system.
514
Abnormal communication
warning of the Sungrow Energy
Meter. (Inverter can be
normally connected to the
grid.)
1. Check whether the power cable
connections of the Energy Meter
are correct.
2. Check whether the RS485
connection is correct.
3. Check if the 120 Ohm (2)
resistor for RS485_2 is pushed to
“ON” when the length of RS485
cable is longer than 100 m.
600
Temporary BDC charging
over-current fault.
Wait a moment for system
recovery or restart the system.
601
Temporary BDC discharging
over-current fault.
602
Clamping capacitor
under-voltage fault.
1. Check the cable connection of
the battery.
2. Wait a moment for system
recovery or restart the system.
603
Temporary clamping capacitor
over-voltage fault.
Wait a moment for system
recovery or restart the system.
608
BDC circuit self-check fault.
612
BDC over-temperature fault.
1. Check and clean the heat sink.
2. Check whether the inverter is
installed in sunlight or the ambient
temperature of the enclosure
exceeds 45℃.
3. Restart the system.
616
BDC hardware over-current
fault.
The system will resume once the
battery charge/discharge current
falls below the upper limit or
restart the system.
620
BDC current sampling fault.
Wait a moment for system
