GBESS 2.4_4.8KWH system user manual
47
E05
Inverter current is over the tolerable
value
E06
Residual current is out of range
Wait until the controller has
re-stabilized.
E07
The GFCI detection circuit is abnormal.
Wait until the controller has
re-stabilized.
E08
Isolation resistance of PV-plant out of
tolerable range before connecting to
the grid.
Check insulation of the system.
E09
Rly-Warning
Wait until the controller has
re-stabilized.
E10
Master-grid
voltage
measurement-value out of tolerable
range.
Re-measure line voltage , contact
the service if grid voltage is within
normal range.
E11
The master-frequency is out of
tolerable range.
Check system frequency and line
voltage. Contact the Service if
system frequency is within normal
range.
E13
No-Utility
Re-measure line voltage; contact
the Service if line voltage is within
normal range.
E14
PV input voltage is over the tolerable
maximum value.
Check the voltage of solar panels
E15
Inverter internal communication fail
Please contact the service if
continue occur
E16
PV over temperature
Allow the unit to cool down
E17
Different value between master and
slave for grid voltage.
Possibly caused by switching actions
on the net. Re-measure line voltage.
Contact the Service if line voltage is
within normal range.
E18
Different value between master and
slave for output DC current.
Wait until the controller has
re-stabilized.
E19
Different value between master and
slave for output DC current.
Wait until the controller has
re-stabilized.
E20
DC bus soft start is over time
Check input voltage
E21
PV inverter soft start is over time
Ch
eck the utility
E22
PV inverter bus voltage is too low.
Wait until the controller has
re-stabilized.
E23
PV inverter Bus voltage is too high.
Wait until the controller has
re-stabilized.
E24
Different value between master and
slave for grid frequency.
Check system frequency and line
voltage. Contact the Service if
system frequency is within normal
range.
