SG320 Solar Pump Inverter with MPPT
Solar Pumping system becomes more and more popular, it can be applied to daily ( underground water), agriculture irrigation, forestry irrigation, desert control, pasture animal husbandry, water supply for islands, wastewater treatment engineering , and so on.
In recent years, with the promotion of the utilization of new energy resources, solar pumping systems are more and more used in municipal engineering, city center squares, parks, tourist sites, resorts and hotels, the landscapes and fountain systems in the residential areas. This system is composed of a solar array, a pump and solar pumping inverter, or GPRS remote control model.
Based on the design philosophy that it is better to store water than electricity, there is no energy storing device such as store battery in the system.
SG320 solar pump inverter feature:
² Maximum power point tracking (MPPT) with fast response speed and stable operation
² Enable to drive for 1 phase AC pumps or 3 phase AC pumps, also compatible with synchronous or asynchronous (PMSM) pump.
² Enable to drive for PMSM high speed and high efficiency pumps without motor ID auto tuning
² Dry run (under load ) protection, lowest speed auto tuning , Pumps maximum current protection, Minimum power input protection...
² The PQ (power/flow) performance curve enables to calculate the flow output from the pump
² Dual mode AC and DC power supply input is available
² Digital signal of water level sensor and analog signal of water level sensor for water tank fulling detect.
² Dedicated hardware design with dual CPU, independent air duct design
² Import IGBT module such as Infineon, Fuji,TYCO to ensure good quality
² Enhanced lightning protection module
² GPRS remote control module for distance monitoring, control, parameters modification, and history data record..
² Efficiency is higher than 99.5%, power factory not less than 0.96 for below 15kw inverter.
