As explained to me by Renogy, if the converter voltage is higher than your MPPT it will simply not work. If the MPPT senses a lower voltage in the wires it will charge the battery at a higher voltage. On mine, the converter is lead acid only and the MPPT will charge it all the time there is sun and low battery.
You might watch a youtube, call whoever made your MPPT or go to Renogy.com and look at some solar learning items they have on on their website that I found easy to understand.
