The output current is not
balanced

BusUVP
The DC bus voltage is too
low
If the configuration of the PV
generator is correct (no ID05 error),
the possible cause may be linked to
insufficient sunlight. The inverter
automatically returns to its normal
operating state when the level of
sunlight is back to normal.

BusOVP
The bus voltage is too high
ID26-ID27 are internal errors of the
inverter. Switch the DC switch OFF,
wait 5 minutes and then switch the
DC switch ON. Check whether the
error has been rectified. If not,
please contact the technical
support department.
