How many VPC would give you a 100% SOC on a 15S or does it not work like that.

Infinisolar is a high voltage inverter - its maximum voltage from the PV panels is 500V.
Its designed really for markets that are grid-tie with feed in tariffs where a system about 3kWp can be made with a single string.
