4.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.
① Perform all electrical installations in accordance with local electrical codes.
② Be aware that only qualified professionals should install and/or replace
APsystems Microinverters.
③ Before installing or using an APsystems Microinverter, please read all
instructions and warnings in the technical documents and on the APsystems
Microinverter system itself as well as on the PV array.
④ Be aware that installation of this equipment includes the risk of electric shock.
⑤ Do not touch any live parts in the system, including the PV array, when the
system has been connected to the electrical grid.
Strongly recommend to install Surge protection Devices in the dedicated meter box.
