Fault information
Possible cause
Action
sunlight, if yes, please do appropriate shading.
4. If there are no such problems, and the failure
persists, please contact the distributor or
after-sales service center.
INV 105% Over Load
Output overload
protection
1. Check the output load and reduce the load
power.
2. If there are no such problems, and the failure
persists, please contact the distributor or
after-sales service center.
INV 125% Over Load
INV 150% Over Load
INV 200% Over Load
BUS FAST Over
VOLT
The instantaneous
voltage of the bus is
higher than the
allowable upper limit of
the inverter.
1. After reduction of the bus voltage, wait until
the inverter recovers.
2. If the failure is repeated, please contact the
distributor or after-sales service center.
BUS Over VOLT
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.
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.
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.
