My contention is that the standard ... solar controller is a straight buck converter....
The market will sell you a controller that is MPPT with a high intake buck converter you can set to 12v battery level for output. Nobody sells one of those without the MPPT feature.
IMO you can get one of these gizmos that will be a PWM 24v panel controller but for much less money.
Wrong! It turns out the controllers have more circuitry in them that is required to work with battery charging as the load.
So my gizmo cannot be used as a charge controller for 24v panels (as proven during testing)
My evil plan has been foiled! :(
