Product Description
SG320 220V Solar Pump Inverter For IM And PMSM AC Pumps Control MPPT Gprs Remotor Control 1 Phase Pump Control
Solar water pumping solution is a fully automatic system designed to provide water at affordable cost for people with limited or no access to electricity. It uses the most advanced SG320 Solar variable speed drive to regulate the speed of a 1/3-phase AC motor depending upon the solar energy available from the solar panel.
This chapter provides an overview of the contents, purpose, compatibility, and the intended audience of this manual. This supplement manual intends to serve as a quick start guide for installing, commissioning and operating the SG320 solar pump inverter. This manual includes all the required parameter settings and program features specific to the solar pump inverter.
Solar Pumping System overview
Solar pumping systems can be applied to all forms of daily use, water pumping for drinking water supply for remote villages and farms without connection to the water grid, for agricultural use such as livestock watering, agricultural irrigation, forestry irrigation, pond management, desert control, and industrial use such as waste water treatment etc.
In recent years, with the promotion of the utilization of renewable energy resources, solar pumping systems are more and more used in municipal engineering, city centre squares, parks, tourist sites, resorts and hotels, and fountain systems in residential areas.
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). The pump, driven by 3-phase AC motor, can draw water from deep wells, rivers and lakes and pour it into storage tanks or reservoirs, or be connected directly to the irrigation system, fountain system, etc. According to the actual system demand and installation condition, different types of pumps such as centrifugal pump, axial flow pump, mixed flow pump or deep well pump can be used.
Solar pump system constitution.
SG320 Solar pump inverter operation theory and features
The solar pump inverter uses the maximum power point tracking (MPPT) control program to improve the efficiency of solar energy systems. The output of the photovoltaic (PV) cell is proportional to its area and intensity, while the output voltage is limited by p-n junction from 0.6 to 0.7 V. Therefore when the output voltage is constant, output power is proportional to intensity and surface area. The current and voltage at which the PV cell generates maximum power is known as the maximum power point.
Several advantages of SG320 solar pump inverter
- 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
