This solar pump inverter is a low voltage AC drive of 0.75kW is designed to operate with energy drawn from solar panel or photovoltaic cells (PV). The inverter is customized to operate in dual supply mode, so the grid connected supply is used in the absence of energy from PV cells. This drive functions with latest in technology maximum power point tracking (MPPT) algorithm to derive maximum power from the PV cells at any instant.
Maximum power point tracking (MPPT) with fast response and stability operation, up to 99.80% efficiency.
Enable to drive for 1 phase AC pumps or 3 phase AC pumps
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 desige
IGBT module such as Infineon, Fuji,TYCO, Star power to ensure good quality
