Advantages:
1, Suitable for single phase pump, three phase pump. Permanent magnet synchronous pump
2, Support PV input and AC input at same time, make system work 24
hours.
3, Built-in MPPT technology with up to 99.9% efficiency.
4, With water level detection function, automatically regulate the
pump flow to prevent dryrunning
5, Water full protection function, when the water is full, inverter
will stop.
6, Support optional LCD keypad, you can know every parameter's
meansing on display,
and you can monitor any 5 group parmaters situation.
7, Support optional GPRS module, you can remotely monitor the
system situation.
Accessories:
1. GPRS (support 2g/3g/4g internet)
It supplies water volume monitoring and operation of inverter from
anywhere at anytim
It’s convenient to visit real time and historical data via web or
Android APP anytime and anywhere.
This easy-to-use platform makes monitoring of solar pump systems
simple and convenient,
far reducing operate time and monitoring costs as well.
2. LCD keypad
Standard inverter are with LED keypad,LCD keypad is optional.
LCD keypad can monitor 4 parameters at the same time. LED keypad
show one parameter only.
LCD keypad with detailed parameter explain,no need use user manual
,more user friendly.
LCD keypad with copy and update and download function.widely used
for government projects and big farms.
3. Output Reactor
When the distance between inverter and pump is more than 70m, you
need use reactor to protect this system.

Technical Questions and solutions
1. How to achieve Automatic start after stop?
If it is controlled by keyboard no need to set any parameter. If
you want to control by external switch
As the default control mode is keypad control, First set P00.06=1
and use a wire or switch to connect com and DI1,When the switch is
closed, the drive run, when the switch is open, the drive stop
2. How to use a float in the water tank to stop the pump if the tank
is full?
If your float signal is digital signal Use float switch to short DI
1 and com and P00.06=1
3.Use level probe in the well for protection against dry running?
Set P24.13=30%-40% and P24.14 P24.16 and P23.21
If your float signal is Analog signal, Connect Ai2 and 10V and GND
and set P41.00=23 and
P41.03-P41.06

2. How to design solar PV water pump system?
Key point: the rated VOC and VMP and power of the PV Array need to
match the input range of
the inverter. If needed, we will provide technical support online.
