MPPT Installation

4cf15d32-1db9-4ddf-a78f-856189f0d664.jpegTruck camper with 2 100w solar panels. Just installed 2 AGM 12v 100ah batteries and a Victron MPPT 100V 30amp 12/24-Volt Solar Charge Controller. This is what I see. Do I have the settings set right? and how do I see the % battery charge?

1. Your PV voltage needs to be 5V higher than the battery voltage to start charging. So you have to connect your panels in series and more sun. Do you have a datasheet of the panels?

2. To see the state of charge (SOC) of the battery you need a BMV or SmartShunt, the MPPT can't do that.
