Q:#Why#is#it#recommended#to#set#up#the#gateway#as#early#as#possible#during#the#installation?#
A: Once the gateway is functioning it will show which individual inverters have DC
connections, even without AC power to the inverters. Solving connection issues before
finalization can help the installation to proceed more efficiently.
2.3 Test the communications between micro inverters and gateway
By looking at the “Installer Mode” screen on the gateway unit, the installer can see if the
gateway is receiving a good signal from all of the micro inverters. See section 4 “Using the
Enecsys Gateway”.
If communications have not been established, it may be necessary to install one or more
repeaters. See section 5 “Using the Enecsys Repeaters”.
2.4 Mount the Enecsys micro inverters and cable harness
The installer must follow the installation design, mount all the micro inverters on the
racking/mounting system, prepare the roof penetration conduit and lay the AC branch bus
cabling. Note that the micro inverters must not be connected at this point.
• The single micro inverters must be installed with the round plastic antenna covers
facing downwards towards the roof.
• See “6.2 Mounting the single micro inverter” or “6.4 Mounting the duo micro
inverter”.
2.5 Inspect and test the AC cabling before it is connected to the mains utility grid
When all of the AC cabling is in place, but before it is connected to the grid, it must be
inspected and tested to verify compliance with the relevant electrical installation standards.
2.6 Connect the micro inverters, AC bus cabling, and ground wire
See “6.5 Installing and connecting the AC bus cabling, Single and Duo” and “6.6.1,
Connection instructions for the Single and Duo micro inverters”, steps 1 through 4. Install the
ground wire (if applicable).
2.7 Connect the DC cables from the PV modules to the micro inverters
See “6.6 1, Connecting the single or duo micro inverter”: step 5.
When the PV modules are connected to the micro inverters, they will immediately start
communicating with the Enecsys gateway.
2.8 Connect the AC cabling to the mains utility grid
See “6.6 1, Connecting the single or duo micro inverter”: step 6.
WARNING
Connection of the AC cable to the mains utility grid must only be done by a
qualified electrician.
