7.5Kw To 30Kw Three Phase 380V Output / Vfd / Vsd Solar Pump Inverter For Irrigation
Solar Pumping System description
The system is composed of a PV generator, a pump and a solar pump inverter. Based on the design philosophy that it is more efficient to store water rather than electricity, there is no energy storing device such as storage battery in the system. The system is prepared to be combined with a elevated water storage, e.g. water tower or an uphill tank installation. The PV generator, an aggregation of PV modules connected in series and in parallel, absorbs solar irradiation and converts it into electrical energy, providing power for the whole system. The pump drive controls and adjusts the system operation and converts the DC produced by the PV module into AC to drive the pump, and adjusts the output frequency in real-time according to the variation of sunlight intensity to realize the maximum power point tracking (MPPT).
Solar Pump Inverter Features
1. Input voltage from 250V DC to 800V DC drive single phase or three phase 380V AC water pump.
2.It can prevent the water pump from dry pumping without water when the water source is dry.
3.The PQ (power/flow) performance curve enables calculating the flow output from the pump.
4.Strong lightning protection.
5.Ambient temperature for using: -10 to +50˚C.
6.The working voltage of solar panel can set by manual or MPPT automatically tracking.
7.Suits for most 3 phase AC pumps.
8. Digital control for fully automatic operation, data storage and protective functions.

How to perform auto tuning for driving PMSM?
1). Set sensorless vector control mode for driving PMSM, F0-01=2
2). Set PMSM motor parameter, F2-00=1, F2-11 ( rated frequency of PMSM), F2-12 ( rated voltage of PMSM), F2-13 ( rated current of PMSM), F2-14 ( rated back EMF or PMSM), F2-15 ( stator resistance of PMSM). The frequency, current and voltage is important parameters, it need to set. )
3). Set F2-10=1 or 2 to perform PMSM ID auto tuning. If the motor is easy to remove from pump, please set F2-10=1, if the motor is difficult to remove from pump, please set F2-10=2. Press the RUN button to perform motor trial running and observe the running frequency and the water yield. If the sunlight radiation is good, and frequency goes up, but water flow is very small. Might the direction of pumps running is not correct, please to change any two phase motor wiring.
