Just curious about the overall design goals of this operating mode?
Putting solar energy into and then taking it out of batteries suffers
about a 30% loss in efficiency. All else being equal it is usually better
to use solar power directly if possible.
Maybe the value of this mode is for hams to use the satellite in the
evenings during play time instead of during the day when schools and
students could benefit.
