The below design calculations are in regards to the power conservation & continued operation
mode of Ixom Watercare, Inc.’s solar-powered mixing control systems.
The SolarBee control system includes a brain board component with pre-programmed
algorithms for reducing motor load and continuing operation by incremental speed reduction,
thus incrementally reducing motor load and load being drawn from the battery. This feature is
automatically enabled when extended low sunlight conditions occur or battery reserve power is
reduced. This feature is commonly referred to as Fallback RPM.
Below is the detailed Fallback RPM chart, based on battery voltage and percentage of
commanded or scheduled run speed, typically programmed for full speed of 80rpm.
