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.
