NOTE TO NEW INSTALLERS: BEFORE STARTING

INSTALLER MONITORING LOGIN;

Before connecting PV modules to the micro-inverters, power up
gateway, and connect it (via ethernet cable provided) to router.
Ensure there is a spare ethernet port on the router.
Ensure that PV modules used are compatible with
the micro-inverters used! Check Compatibility List.
Always connect PV system on its own
dedicated 30mAmp RCD/RCBO.
Otherwise, RCD risks tripping.
2
Set up the monitoring BEFORE installation – you can then
check if installation is working properly while still onsite.
Ensure that the gateway has a smiley face, if not, check which of
the icons in the bottom left corner has a cross, to locate problem.
Each micro-inverter has to be mounted with the
round white plastic disc pointing down into loft.
Max 16 micro-inverters per 30mAmp
RCD/RCBO.
3
Make a MAP of the install with inverter positioning, and
ensure the inverters full serial numbers are entered
correctly in accordance with their physical position.
Run a communication check by connecting repeater in same
room as gateway. A “1” should show on gateway in ~2 min. If ok,
reposition repeater to the loft/1st floor and check again if “1” shows.
Connect extension cables to distribution units
making sure the grey pins are in the male connectors,
and a “click” is heard.
A/C local double pole isolator is still
required possible in loft position.
4
The “Installation Name” is what is shown on monitoring.
Do not use precise address as name. Agree name with
customer. Make sure customer details are accurate.
As soon as PV modules are connected to micro-inverters (only
DC power is needed), these start communicating and should
appear on gateway which starts counting them each every ~2
min.
Long fixing screws (12mm+) maybe required for
fixing inverters to the mounting rail system. Screws
should be 8mm diameter.
When large number of inverters are
installed, split AC bus to spread current
for better harvest. This requires 1 extra
distribution unit and end cap.
5
Make the panels as large as possible for easy viewing.
When labelling panels, preferably use the last 3
numbers of the inverter serial number. Print screen; can
be used for install.
Gateway counts all of the micro-inverters AND the repeaters. So,
if there are 9 micro-inverters and 1 repeater, gateway should
show 10. If not, check roof connections as number on gateway
must match. Max number of inverters per gateway = 40
The micro-inverters need to be placed behind the
panels & not touching the panels or the junction box,
with >1cm gap between the inverter and the panel.
High voltage tests - 1000V Insulation
resistance tests - to be carried out without
inverters connected. 500V MAX if
inverters connected.
6
Once all data in the monitoring is complete, press
“Launch installation”. As soon as physical install is
complete and inverters start reporting, system can be
seen on monitoring.
To check signal strength put gateway in installer mode: press into
hole on the side for 5 secs with safety pin- display will flash.
After check, always put back into normal mode by pressing into
hole again.
-1 extension cable for 2 inverters.
-1 distribution unit for 2 inverters. 3 possible if total
number of micro-inverters is odd.
A/C test procedures to be carried out in
accordance with BS7671 at the furthest
point which will be at the end of the
extension cabling to verify cabling.
7
To see monitoring of installation, log in and choose
“cus­tomer view” and pick the new installation from the
list. Check on “system view” if all inverters are showing
>0W.
When on installer mode check for a “√”. A “X” or “?” means the
signal strength is not strong. Move/add repeaters until you get a
“√”.
-Max 16 X SMI-200 per AC branch.
-Max 13 X SMI-240 per AC branch.
-1 AC grid connect cable per AC branch.
No high voltage string testing is required.
8
Do not remove scaffolding until monitoring is set up in
case roof system is not connected properly, requiring
roof access.
Some installations may need more than one repeater depending
on the distance/obstruction between the gateway and the
micro-inverters.
Always take spare extension cables, distribution
units, and end caps.
9
DPA (Data Protection Act) Form needs to be signed by
customer otherwise Enecsys cannot release customer
login details.
If the house has aluminium foil insulation a double repeater with
a fixed antennae and its antennae cable form may need to be
installed on roof.
Distribution unit and extension cable to be securely
fixed to railing system. Ensure all cabling is dry when
installing.
Monitoring will only work properly if there is full connection:
inverters-gateway-router-internet.
No distribution unit or cable should be left with open
ends. Put end caps to any opening. Risk of RCD
tripping otherwise.
