Installation
WARNING:
Perform all electrical installations in accordance
with local electrical codes. Installation of this equipment
includes the risk of electric shock. Quali
fi
ed professionals
should install and/or replace MicroGT 500 inverters.
WARNING:
Before installing or using a MicroGT 500
inverter, please read all instructions and warnings in the
technical documents and on the microinverter system itself,
as well as on the PV array.
WARNING:
Once the system is connected to the electrical
grid,
do not
touch any live parts in the system, including
the PV array.
Additional Installation Components to Purchase
• AC connector cable (PN: ME-MGT-AC-F, x1/branch)
• AC extension connector cable (PN: ME-MGT-AC-EXT, if required)
• AC 25A female termination cap (32mm – x1/branch)
• Pair of MC4 caps (male and female)
Required Parts and Tools
In addition to your PV array and its associated hardware, the
following tools are required for assembly:
• One AC connection junction box per branch circuit
• Mounting hardware suitable for module racking
• Sockets and wrenches for mounting hardware
• Continuous grounding conductor and grounding washers
• Phillips
screwdriver
• Torque
wrench
Note:
MicroGT 500 inverters are designed to only operate when they
can sense power coming from the grid. Even if they are plugged into
the PV array, they will not turn themselves on until they can read
power from the grid.
WARNING:
DO NOT connect MicroGT 500 inverters to
the utility grid or energize the AC circuit until you have
completed all of the installation procedures.
