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.
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.
