Got a seperate MPPT even though my 25A DC/DC charger has a solar imput, looking to get two charging sources at one and can still plug in a solare blanket into the DC/DC charger. Still working out a few issue with the help of Kick Ass tech with over voltage alarm. but this only happens with no load and a fully charged battery. Have since instaled a isolation switch on the MPPT for when there is no load on the system.
