VbusRmsUnbalance
Asymmetrical bus
voltage RMS
Internal error of the
inverter. Switch off the
inverter, wait 5 minutes
and then switch the unit
on again.
If the error persists,
contact technical support.
ID066
VbusInstantUnbalance
The transient value
of the bus voltage
is unbalanced
ID067
BusUVP
The DC bus
voltage is too low
during mains
connection
ID068
BusZVP
The DC bus
voltage is too low
ID069
PVOVP
The PV input
voltage is too high
Check whether the PV
series voltage (Voc) is
higher than the maximum
input voltage of the
inverter. If this is the
case, adjust the number
of PV modules in series.
After the correction, the
inverter automatically
returns to its normal
state.
ID070
BatOVP
Battery overvoltage
Check whether the
voltage of the battery is
higher than the maximum
input voltage of the
inverter. If this is the
case, adjust the number
of battery modules in
series.
