### Mppt want's 1.5X battery voltage to run properly?

I was told this as a general rule and wanted to know how much of it is true?

With a 12v system, will a standard 18 vmp panel be enough voltage to run a victron 100/50? Say two 250watt panels in parallel? Will this voltage be enough if the panel wattage is noticable smaller than the combined battery charge rate + loads? In this case will the voltage sag?

Thanks
