The $102 Eco-Worthy MPPT 20a controller has an adjustable high set point to reach Vabs, an adjustable Float, and the voltage that triggers a return to MPPT is not adjustable but is 13.2v.

When the trailer is in storage or on 110V, I set the float back to 13.2V (the same float V as the Progressive Dynamics charger when on 110v). That seems to work fine with little water loss over long periods although I think my batts call for 13.1V
But when boondocking, I appreciate being able to set the float higher (13.6V) so MPPT kicks in earlier at a higher voltage. Have been told that the higher "float" voltage should not be a problem for the batteries as they'll be all night without any charging.
So far this has worked well. But I suppose it could set it even higher when boondocking and the Rogue kept in MPPT as much as possible.
