Page 5: Apsystems Yc500 System Introduction
APsystems YC500 System Introduction The APsystems Microinverter is used in utility-interactive grid-tied applications, comprised of three key elements: APsystems Microinverter APsystems Energy Communication Unit (ECU) APsystems Energy Monitor and Analysis (EMA) web-based monitoring and analysis system Figure 1... - Page 6 The distributed APsystems Microinverter system ensures that no single point of system failure exists across the PV system. APsystems Microinverters are designed to operate at full power at ambient outdoor temperatures of up to 149°F (65°C). The inverter housing is designed for outdoor installation and complies with the NEMA 6 environmental enclosure rating.

Special Statement! An AC GFCI device should not be used to protect the dedicated circuit to the APsystems microinverter even though it is an outside circuit. None of the small GFCI devices (5mA-30 mA) are designed for back feeding and will be damaged if back feed. In a similar manner, AC AFCIs have not been evaluated for back feeding and may be damaged if back feed with the output of a PV inverter. -
Page 9: Yc500A Installation Procedures
YC500A Installation Procedures APsystems Microinverters are designed to only operate when they can sense power coming from the grid. Even if they are plugged into the solar array, they will not turn themselves on until they can read power from the grid. -
