Other 12V Sources with a 24V-12V converter
Switching to a 24V battery bank has gone well so far. The 40A Victron 24V-12V converter seems to handle all my 12V loads without issue. It keeps the V at about 13.2V But a question: there can some...

THIRTY Volts WILL TIDE YOU OVER JUST FINE. This ain't a Betty Crocker moment.
Yep. And thank you for the Meanwell suggestion.

Using the most widely used temperature compensation formula:
-0.005 V per C per 2 V cell
Yields at 0C (32F) -0.005(0-25)12 = 1.5V for a 24V battery. And this implies that for ideal flooded bulk charging you would need a 29.6+1.5 or 31.1V charging source.

And that's what my solar charger does. Max is 32.5V
Temp compensated with probe at the batteries.
(But I've reduced the temp comp to -0.004V per cell per degree C)
If necessary on cloudy days and if I want to equalize or whatever, the 30V from the Meanwell will provide that extra ooomph for the solar to get up to the required V.
Not sure if some of you EVER see sunshine where you live ...
