Todd chargers in 24 VDC systems [RE-wrenches]

[Steve Willey - Backwoods Solar Electric]

Yes, I suppose just like you did with Todd you could series the Truecharge
40+ to 24 volts, but I have some doubts about their advanced functions and
haven't tried it:
They do have some cycling where they shut down and follow battery voltage
for 5 seconds.  I run two parallel and they do that the first time almost
simultaneously but the second or third cycles they perform are not quite
simultaneous so I suspect big trouble there if used in series. Of course .
With center tap connected to battery center tap, it should work.  I don't
think current differences would be too much either.But I would still like to
see 24 volt models and larger amp ratings too.
