<p>Or can I set the Rebulk voltage for the pair of Outback VFX3524 inverters on the Mate to lower than the Refloat? Will it let me do that?</p>
<p>I have very limited access to the equipment to experiment. </p>

<p>The problem I am running into is that REFLOAT keeps initiating and the system never gets triggered to go back into the bulk / absorb cycle. </p>
<p>Can I avoid this by turning the float time to zero? </p>

Until the Absorb voltage value is achieved, you will be bulk charging. You can only force Float or Bulk. <br>
