allowable upper limit
of the inverter.
2. If the failure is repeated, please contact the
distributor or after-sales service center.
BUS Hardware Over
VOLT
The hardware
detects that the
instantaneous
voltage value of the
bus is higher than the
allowable upper limit
of the inverter.
1. Check whether the PV input voltage exceeds the
allowable range of inverter protection
parameters.
2. After reduction of the bus voltage, restart the
inverter
3. If the failure is repeated, please contact the
distributor or after-sales service center.
BUS Low VOLT
The average bus
voltage is lower than
the allowable lower
limit of the inverter.
1. Wait until the inverter recovers.
2. If the failure is repeated, please contact the
distributor or after-sales service center.
BUS Fast Low VOLT
BUS Short Fault
A sudden change in
external conditions
causes damage to
internal components
Please contact the distributor or after-sales service
center.
GRID Relay Fault The relay cannot be
closed and
disconnected
properly.
1. Restart the inverter;
2. If the failure is repeated, please contact the
distributor or after-sales service center.
INV Relay Fault
LOAD Relay Fault
MCU SCI
Communication Fault
No monitoring data
was received.
1. Restart the inverter;
2. If the failure is repeated, please contact the
distributor or after-sales service center.

Output overload
protection during off-
grid to grid-tied
1. Check the output load and reduce the load
power.
2. If the failure is repeated, contact the distributor
or after-sales service center.

BYPASS 200% Over
Load
PV1 Over VOLT
The PV1 or PV2
voltage is higher than
the bus voltage.
1. Check whether the PV input end is normal;
2. Check whether the PV input configuration
exceeds the allowable range of inverter
protection parameters.
