BYPASS 105% Over
Load
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 125% Over

BYPASS 150% Over
Load
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.
3. If there are no such problems, and the failure
persists, please contact the distributor or
after-sales service center.
PV2 Over VOLT
PV1 FAST Over
CURR
The average
instantaneous input
current of PV1 or PV2
is higher than the set
upper limit.
1. Check whether the PV input end is normal.
2. Check whether the PV input configuration
exceeds the allowable range of inverter
protection parameters.
3. If there are no such problems, and the failure
persists, please contact the distributor or
after-sales service center.
PV2 FAST Over
CURR
PV1 Over CURR
PV2 Over CURR
The average input
current of PV1 or PV2
is higher than the
upper limit.
1. Check whether the PV input end is normal.
2. Check whether the PV input configuration
exceeds the allowable range of inverter
protection parameters.
3. If there are no such problems, and the failure
persists after restarting the inverter, please
contact the distributor or after-sales service
center.
INSU.TO GROUND
IMPE.
Short circuit of PV
string to protective
earth, long humid
installation
environment of PV
string
1. Check whether the inverter is grounded
reliably.
2. Check whether the positive and negative
electrodes of the PV panel are short connected
with the ground wire.
3. Wait until the inverter recovers.
4. If the failure persists, please contact the
distributor or after-sales service center.
