<p>While not as inexpensive as David's solution, I have used Mean
Well converters with success. This manufacturer supplied the DC-DC
step-down converters used by Wattsun for their tracker drives, so
there's a pretty long history with them. Check out

They say 110-240 vac input but they rectify the input to DC.
I have used them to run 12 and 24 volt stuff off of 48 vdc and
even 400 vdc. They operate down to about 35 volts dc. They are
available in a variety of output voltage and current. And they
are isolated. And they only cost a few dollars. </div>

Since Solar Converters seems to have evaporated, I'm not
sure where to
look for a 48 to 24 V DC to DC converter. Samlex has 24 to
12. It seems
like someone mentioned a Canadian company that makes
these. <br>
<br>
I need to step down power from a 48 V battery bank to
power El Sid pumps
for an offgrid <font size="2">hydronic</font> heating
system.
