I am in the process of figuring out adding solar to my two bank setup (start battery + house batteries) and have been looking at this one: https://www.renogy.com/dcc50s-12v-50a-dc-dc-on-board-battery-charger-with-mppt/ as a possibility. However, it is relatively expensive and doesn't include monitoring or bluetooth connectivity without additional devices. I think I might go to go with a Victron controller instead and just charge the house batteries with solar but haven't decided for sure. Would be interested if anyone has experience with the renology dc-dc mppt charge controller. One nice thing about it is that it will not load down the alternator so much the way the bluesea relay suddenly connects the house and starter batteries shortly after the engine starts. Second advantage is supporting a mixed bank if I upgrade the house batteries to lithium at some point.
