According to customer needs, models with 500V and 660V voltage levels can be provided.
Usually a HMI with special air compressor program is needed. The HMI operation is intuitive and simple, and the air compressor can be debugged without instructions. In addition, in order to meet the operating habits of different customers, an LCD keyboard can also be selected to realize all parameter settings and debugging of the integrated machine.
Hibernation is a function for saving energy, when the pressure/flow requirement is very little for a long time, VFD enter to hibernation status. There are 2 kinds of hibernation, according to the running frequency or deviation, the hibernation internal logic is as attachment.
If motor cable or well depth is >50 meters, we recommended that you please buy AC output reactor,for reducing over-current issue and reducing high voltage shock.
Yes, but solar power is unstable, may not keep runs 50Hz all the time, so if your speed requirment is lower is acceptable.
1.Insure solar input total Vmp>=550VDC.
2.When weak light or cloudy is normal.
3.If configuration is no issue,and frequence keep under 50Hz,please contact INVT company.
Recommanded use float switch sensor,don't support analog sensor.
Only need to set P15.05 lower frequence of PI output,no need to set P00.05.
1.General connection：Pump LN connect to inverter UW.
2.Three wires connection:Remove capacitor,then connect with UVW cable,ensure resistance of UW is minimum,resistance of UV is maximum.Short connect S4&COM terminal.
