So yeah, it seems history repeats itself.  The Redarc BCDC1225 is not reliable in switching between solar inputs and 12V input derived from the mains.

At least this morning’s wake-up call was a little later in the morning:

We’re now rigging up the Xantrex charger that I was using in early testing and will probably use that for mains. I have a box wired up with a mains SSR for switching power to it.  I think that’ll be the long-term plan and the Redarc charger will be retired from service, perhaps we might use it in some non-critical portable station.
