What is voltage rise?

Voltage rise is the condition whereby an inverter-based system will raise the voltage at the inverter in order to compensate for voltage drop due to the loading of the conductors. Often this compensation has the consequence of raising the voltage at the point of interconnection. YVEA requires voltage rise calculations for all systems with an inverter located greater than 50 feet from the revenue meter. Voltage rise can be compensated with power factor correction, which is a feature of UL1741 SA-tested inverters. According to IEEE 1547, this voltage rise may also be used to maintain voltage levels on the primary distribution system.
