State 101
PV Array
under-voltage
Inverter shutdown
and will
automatically
restart after it
disappear
Output energy from
PV array is not
enough
Please check PV input
voltage and make sure
the voltage is within
inverter input voltage
range.
Notice: In cloudy days,
morning and late in
afternoon, this situation
is normal.
State 109
Dry alarm
Inverter shut down
till the water level
reach the higher
water level sensor,
inverter can restart
automatically.
Water level of water
source is lower than
lower level sensor,
even lower than inlet
of pump.
1. Please check the
water level, if the water
level is ok, please
check whether there
have air inside pump or
not.
2. Please check the
position of water level
sensor.
State 110
Weak
sunshine
Inverter shutdown.
The status
disappear, inverter
can restart
automatically.
The energy
produced by PV
array is low.
Usually appears in
early morning, late in
the afternoon and
cloudy days. This
situation is aim to
protect the motor of
pump.
State 114
Overflow
alarm
Inverter shut down
till water level in
tank is higher than
higher water level
sensor, and it can
restart
automatically
when the status
disappears
Water level in tank is
higher than higher
level alarm of set
If this situation appears
more than once, please
check onsite and set
the water level sensor
at a proper height.
Fault100
Driver
over-current
Inverter shutdown
and will restart
automatically after
the fault
disappears
1. Short circuit of
inverter output wires;
2. Hardware circuit
damage
Please check whether
there have short circuit
situation between 3
phase output wires
Fault105
Over-load
Inverter shutdown
and will restart
automatically after
the fault
disappears
The capacity of load
is higher than rated
output power of
inverter.
Please make sure the
system is proper
designed. The power of
pump motor should not
be higher than inverter
output.
Fault108
AC
over-current
Inverter shutdown
and will restart
automatically after
1. The capacity of
load is higher than
rated output power
1. Inspect pump motor;
2. Inspect pipe system
