after FE.19 (dry run protection automatic recovery) time, automatically resume to running state;
D. Over-current Protection
During the operation of the photovoltaic pump, for some reason, the output current is greater than
FE.20(Over current protection detection current), and after FE.21 (Over current protection detection time)
time, enters into standby protection state, while the keyboard warning " A.oLd "; after entering into the
standby protection state and after FE.22 (over current protection automatic recovery)time, automatically
resume to running state;
E. Minimum Power Protection
During the operation of the photovoltaic pump, for some reason, the output power is less than
FE.23(minimum power protection value), and after FE.24 (minimum power protection detection time) time,
enters into standby protection state, while the keyboard warning "A.LPr"; after entering into the standby
protection state and after FE.25 (minimum power automatic recovery)time, automatically resume to
running state;
F. Fulfilled Water Protection
Detect the water fulfilled alarm level and low water level through two X terminals to realize automatic level
control. Wherein FE.27 is the water fulfill protection detection time and FE.28 is fulfilled water protection
exit time, and X 3 terminal is defined as the input of solar water fulfilled detection alarm signal, and X4
terminal is defined as the input of solar water fulfilled detection alarm reset signal. The warning signal is
shown as "A.Ful"
G. Alarm Recovery Mode: 0: automatic recovery; 1: manual recovery
This option is for low frequency protection, dry run protection, over-current protection, minimum power
function; you can select the alarm restoration mode by FE.26. When you select 0 for automatic recovery,
you can also press the "RESET" button for long to stop operation during fault warning displaying; when
you select 1 for manual recovery, you can press the "RESET" button to manually clear, or press "RESET"
button for long to achieve stop operation.
H. PQ Curve Function
This model provides a self-defined PQ curve for users to set up five groups of PQ corresponding points
according to the pump cases, to achieve calculation of real-time flow speed, daily flow, cumulative flow,
daily generated power and cumulative electricity consumption; of which by default, daily flow and
generated power are calculated basing on 7h in a day.
I. AC/DC Auto-switching Function
The inverter can support multi-power auto-switching between solar DC power and AC power after
optionally equipping AC/DC auto-switching module. When sunlight is very weak, it is able to switch to AC
power automatically so that ensuring continuously working to achieve water-supply stability. When
sunlight turns well, it switches back to solar DC power. This function affords to guarantee system working
stably for 24 hours every day.
J. Status Check
When the solar pump is running, you can check FE.01 to confirm the current operating status.
