Hi. I’m looking for the minimum MPPT voltage for the SmartSolar MPPT 100/20-48V specifically or more generally wondering whether it’s able to charge a 48 V battery bank from a PV voltage less than 48 V. Thanks.

Hi that wont work

pv voltage needs to be at least 5v higher than battery voltage to start the mppt, when started it needs to be 1v higher
