Replace converter with 24v PS and Solar Controller

So after upgrading our batteries to 2 GC2 costco's and realizing they need 15.3v to charge and that no converter can do this... Is there any reason that a 24v 700watt Power supply couldn't feed a t...

The TS-45 has no DC to DC voltage converting circuitry in it like an MPPT control would. A power supply does not behave like a solar panel.
You can call Morningstar and ask them but I don't think it will work.


I bet it will work. I have owned a couple of the MS Sunsaver PWM controllers, and they can accept a power supply as input. If he already owns the Tristar, and if MS allows it, it should work.

Even PWM controllers convert one DC voltage to another, so I don't get your thinking on that.
