Page 8: Apsystems Microinverter System Installation
APsystems Microinverter System Installation A PV system using APsystems Microinverters is simple to install. Each Microinverter easily mounts on the PV racking, directly beneath the PV module(s). Low voltage DC wires connect from the PV module directly to the Microinverter, eliminating the risk of high DC voltage. Installation MUST comply with local regulations and technical rules. -
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. Do NOT connect APsystems Microinverters to the WARNING: utility grid or energize the AC circuit until you have completed... -
