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.
VFD500-PV 5.5KW 7.5kw 380V inverter picture:
1. 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
For 220V single phase motor connection
1: Single phase asynchronous motor wiring method (without starting capacitor):
Notice: U is connected to the common end of the starting winding and the working winding, V is connected to the starting winding, and W is connected to the working winding;
Single-phase asynchronous motor if the rotary steering is not correct, you can change the V and W wiring or set P22.13=1.
First solution: Set parameter P11.01=1 (Single phase motor type without capacitor) or second solution: set P00.11=31 if your motor frequency is 50 hz or set P00.11=32 if your motor frequency is 60HZ
For 220V single phase motor connection
2:Single-phase asynchronous motor wiring method (with capacitor)
Notice1:First solution: Connect motor cable to power terminal U and V and enter BSC mode to Set parameter P23.15=0(output phase loss shielding protection) or second solution: set macro P00.11=21 if your motor frequency is 50HZ or set P00.11=22 if your motor frequency is 60HZ
