016
Output overload, The
configured module
power is excessively
large and out of the
normal operation range
of the inverter.
Wait for the inverter to return to normal.
If the fault still exists, contact SUNGROW.
017
Grid voltage unbalance,
the inverter detects
unbalanced three-
phase grid voltage
Generally, the inverter will be reconnected
to the grid after the grid returns to normal. If
the fault occurs repeatedly:
1. Measure the actual grid voltage. If grid
phase voltages differ greatly, contact the
power company for solutions.
2. If the voltage difference between the
three phases is within the permissible range
of the local power company, modify the grid
voltage imbalance parameter through the
App or LCD screen.
3. If the fault is not caused by the foregoing
reasons and still exists, contact SUNGROW.
019-020
Device anomaly
Wait for the inverter to return to normal.
Disconnect the AC and DC switches, and
reconnect the AC and DC switches 15
minutes later to restart the inverter.
If the fault still exists, contact SUNGROW.
021-022
Device anomaly
Wait for the inverter to return to normal.
Disconnect the AC and DC switches, and
reconnect the AC and DC switches 15
minutes later to restart the inverter.
If the fault still exists, contact SUNGROW.

Device anomaly
Wait for the inverter to return to normal.
Disconnect the AC and DC switches, and
reconnect the AC and DC switches 15
minutes later to restart the inverter.
