2. Applications
RSI is designed for continuous as well as intermittent
operation. The system is suitable for various water
supply systems including irrigation.
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.
Application example
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 all cables from the solar panels can
be connected into one set of power input cables before
connecting them to an RSI.

m, it is necessary to add extra surge protection closer to the solar panel.
