Microinverter System Installation
Setting up microinverters for a PV system is simple. 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 risks associated with 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
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. 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.
WARNING:
Perform all electrical installations in accordance with local
electrical codes.
WARNING
:
Be aware that only qualified professionals should install
and/or replace microinverters.
WARNING:
Before installing or using a microinverter, please read all instructions
and warnings in the technical documents, on the microinverter system itself, as
well as on the PV array.
WARNING:
Be aware that installation of this equipment includes the
risk of electric shock.
WARNING:
Do not touch any live parts in the system, including the
PV array while the system is connected to the electrical grid.
NOTE:
It is strongly recommend to install surge protection devices in the
dedicated meter box.
