4KW 3Phase Borehole Hybrid Solar Inverter

Hybrid solar pump inverter feature:
Maximum power point tracking (MPPT) with fast response speed and stable operation
Enable to drive for 1 phase AC pumps or 3 phase AC pumps, also compatible with synchronous or asynchronous (PMSM) pump.
Enable to drive for PMSM high speed and high efficiency pumps without motor ID auto tuning
Dry run (under load ) protection, lowest speed auto tuning , Pumps maximum current protection, Minimum power input protection…
The PQ (power/flow) performance curve enables to calculate the flow output from the pump
Dual mode AC and DC power supply input is available
Digital signal of water level sensor and analog signal of water level sensor for water tank fulling detect.
Dedicated hardware design with dual CPU, independent air duct design
Import IGBT module such as Infineon to ensure good quality
Enhanced lightning protection module
GPRS remote control module for distance monitoring, control, parameters modification, and history data record..
Efficiency is higher than 99.5%, power factory not less than 0.96 for below 15kw inverter.
