Solar pumping systems for reliable Water Supply in Africa

The Grundfos Renewable Solar Inverter (RSI) is an off-grid solar inverter converting the DC power output from the solar panel to AC power supply for pump operation.

The RSI is designed for continuous as well as intermittent operation. The system is suitable for various water supply systems including irrigation.

The RSI can be used in existing systems with submersible pumps or dry-installed pumps, thus providing a very wide range of applications allowing you to leverage renewable energy sources with the ability to back up the system with grid or generator power.

The water production of an RSI system depends on the availability of solar power. The typical result is excess water production in the afternoon and insufficient water production in the morning and evening. A system equipped with a storage water tank will enable a stable water supply throughout the day. In a combiner box (junction box), all cables from the solar panels can be connected into one set of power input cables before connecting them to an RSI.

The RSI is incredibly easy to setup and install, and pairs easily with SP submersible pumps as well as a broad range of Grundfos pumps, creating a modular system which allows maximum components flexibility. The list below contains the pump types for use in applications with the RSI: GRUNDFOS CR - GRUNDFOS SP - GRUNDFOS NB, NK - GRUNDFOS MTR - GRUNDFOS CM - GRUNDFOS TP

The RSI is designed to achieve enclosure class IP66. This means the inverter is weatherproof and can be installed outside. The RSI is AC and DC compatible. The RSI can be connected to the grid or a generator as back-up power during solar panel disruptions.

The AC compatibility also allows the end user to connect the inverter to three-phase power in their workshop for off-site setup which enables a fast and simple on-site installation. Solar power (DC) and AC power must never under any circumstances be connected at the same time. To prevent the AC and DC power sources from being connected by accident, we strongly recommend that you use an interlocked changeover switch The switch must be sized according to the RSI power ratings.

Advanced MPPT software continuously optimises the system by compensating for environmental effects on solar panel array, improving power and water output by up to 30 %. Environmental effects cover temperature compensation, handling of multiple local power points due to partial shading, and protection against power oscillation due to rapid cloud movement.
