[RE-wrenches] 24V charging with 60 cell modules

[David Katz]

Hi Mac,
You can do it if you don't need much power.  That module will float and equalize the battery but as the voltage rises, the current will drop significantly.  I used one 230 watt module for a year to charge a 24 volt battery with an 11 watt load on it and it worked fine.  It is probably cheaper than buying two 50 watt 36 cell modules and putting them in series.

Hello wrenches,

Is there a good method to charge 24V battery bank with single 60 cell modules?  Ideally, I'd like to charge a 24 V bank with a Kyocera 245GX-LFB.  However, at NOTC the Vmp is 26.8V.  Any good way to do this?

Thanks in advance.
