Introduction
The RSI Renewable Solar Inverter is a high-performance off-grid solar inverter designed specifically for solar-powered water pumping applications. With a 37kW capacity, 3-phase 380–440V output, and 72A rated current, it provides reliable and efficient pump operation for demanding solar installations. In addition, its dedicated solar pumping design makes it a practical solution for agricultural, irrigation, and water supply applications.
General Description
The RSI is designed to expand and enhance solar pumping systems by efficiently converting solar energy into power for water pumps. It is suitable for submersible, multistage, and single-stage pumps, making it a versatile solution for agricultural irrigation, water supply, and other off-grid pumping applications. Furthermore, its IP66-rated enclosure provides strong protection against dust and water, supporting reliable outdoor installation and long-term operation.
Powerful 37kW Solar Pumping Performance
With a 37kW power rating and 72A output current, the RSI provides stable power for high-capacity solar pumping systems. As a result, it helps operate pumps efficiently while reducing reliance on conventional grid electricity. This makes the inverter suitable for demanding agricultural, irrigation, and commercial water pumping applications.
Wide 3-Phase Voltage Compatibility
The inverter supports a 3-phase 380–440V output range, making it suitable for a wide variety of industrial and agricultural pumping systems. Therefore, the RSI can provide consistent motor operation across compatible pump applications while supporting reliable solar-powered water pumping performance.
Compatible with Multiple Pump Types
The RSI is designed to work with submersible, multistage, and single-stage pumps. This flexibility makes it suitable for different water pumping requirements, including irrigation, water wells, agricultural applications, and commercial water supply systems. Moreover, its compatibility with multiple pump types allows the same solar inverter solution to support a range of off-grid pumping needs.
