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 Meter.
(Inverter can be normally
connected to the grid.)
1. Check whether the power cable
connections of the 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

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 recovery
or restart the system.
623
Slave DSP communication fault.
624
BDC soft-start fault.
800,802
804,807
