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.

Use level probe in the well for protection against dry running
1st solution: See self learning of dry run
2nd solution: do it manually Set P24.13=30%-60%(as per real empty load
current percentage based on rated current) and P24.14 P24.16 and
P23.21
3rd solution: If your sensor is digital switch ,just short D4 and com
4th solution:If your float signal is Analog signal, Connect Ai2 and
10V and GND and set P41.00=23 and
P41.03-P41.06
How to set minimum frequency ( for example) 30hz and maximum 50HZ
Set P47.05=30HZ and 47.06 to some time and 47.07 to some time.
Please refer to details of P47.05-47.07
If pump is 60HZ frequency, how to set max frequency?
Notice: If your motor rated frequency is 60HZ First solution for
you, P01.06=P01.08=P11.05=60HZ.
Quick setting and easier way: you should set P00.11=02 If your
motor is three phase; if your motor is single phase with capacitor
,set P00.11=22;If your motor is single phase without capacitor ,set
P00.11=32
How to check and solve basic problem of inverter trips and error
a:Check the total vmp and voc of solar panels ,solar panel
technical data
b:Check motor pump power and rated current
c: Check the distance between motor and inverter
d: Check trip record r25.00 r25.01 25.02 25.03 r26.00 r26.01 r26.02
r26.03
e: Check troubleshooting fault and find relevant solutions
f : Check if motor insulation has been damaged or motor is blocked
