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.
WARNING:
Do NOT connect APsystems Microinverters to the
utility grid or energize the AC circuit until you have completed
all of the installation procedures as described in the following
sections.
