Not all but most salespeople unfortunately don't know what they are talking about, more than likely they don't own an RV and/or don't understand the technical aspect of the equipment onboard. Why would anyone have solar if not to charge their battery bank while unplugged from power, sure they offer some charge while plugged in when converter or inverter charger is doing most of the work. At 12.7vdc battery is not receiving a charge, a proper float charge is at least above 13.2 volts, any effective charging requires a voltage above battery voltage. With a 30 amp controller you can add a couple of more panels before upsizing controller.
