Accessories:

1. GPRS (support 2g/3g/4g internet)

VEIKONG solar pump inverterGPRS system is a professionamonitoring system platformmanaging solar pump plants

It's convenient to visit real timeand historical data via web orIOS & Android APP anytime andanywhere.



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 and Sine Wave Filter

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:

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
