Chapter 2 Installation Recommendations
2.1. Site requirements for Enecsys micro inverters and monitoring system
The following things are required if the Enecsys Monitoring system is used:
• The customer must have a broadband Internet connection.
• There must be an unused Ethernet port on the customer’s router to connect to the Enec-
sys Gateway so the Gateway can communicate with the online monitoring system. The
information provided by the Enecsys Gateway is used to troubleshoot the installation as it
progresses. See “Chapter 4 Using the Enecsys Gateway” on page 12.
• If the roof is made of metal or lined with metal foil, it may be necessary to install one or
more repeaters right below it, in a loft or attic, for example. See “Chapter 5 Using Enecsys
Repeaters” on page 21.
• If a repeater or repeaters are necessary, there must be power outlets in the required loca-
tions. See “5.2. Using Repeaters” on page 21.
2.2. Install the Enecsys Gateway
At the earliest possible stage during the onsite installation, the installer should connect the
Enecsys Gateway to the customer’s router using the Ethernet cable provided. When the Gate-
way is
powered up, it will be ready to start monitoring the micro inverters as soon as they are
connected to the PV panels on an individual basis. (See “3 Installing the Gateway”.)
Q: Why is it recommended to set up the Gateway as early as possible during the instal-
lation?
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
.
2.3. Plan the cabling layout
The installer must follow the installation design for module layout. Trunk cabling comes in
portrait and landscape spacing
and the system includes a variety of to
accommodate
needs.
2.4. Lay out AC cabling; test, then connect to Point of Common Connection
All connections and terminations must be completed per the install la ti on design. See “6.2.
Installing and connecting the AC bus cabling” on page 28.
When all of the AC cabling is in place, but before it is connected to the point of common con-
nection (POCC), it must be inspected and tested to verify proper connection and compliance
with the relevant electrical installation standards.

WARNING
Connection of the AC cable to the mains utility grid must only be done by
personnel.
