Selecting cable type
The AC BUS cable is installed by simply rolling out the desired length of cable and
cutting it size. One end is wired directly into the junction box and the head of the
branch circuit, eliminating the need for a separate AC interconnect cable. The other
end is seal from the environment using an AC trunk end cap. The type of AC BUS
cable is decided by the PV modules installation orientation. Envertech suggests select
cable type as following description:

Installing Envertech-EVT500 Microinverter System
The installation must be carried out with the equipment
disconnected from the grid and with the photovoltaic panels
shaded or isolated.
1.
Position AC BUS cable
Make sure no more than 8 Microinverters be connected to each branch of AC BUS.
Run the AC BUS cable along
the frame structure provided
for installing the photovoltaic
modules.
2.
Fix Microinverter to photovoltaic module frame
In order to facilitate positioning, it could be useful to mark the approximate centre of
each photovoltaic module on the frame.
Mount all the Microinverter
under the PV module, away
from rain and sun and with
logo side facing downwards.
3.
Ground the Microinverter and PV panels
Microinverter and photovoltaic panels must be connected to an equipment grounding
conductor in accordance with the legislation in force in the country of installation.
The inverter can be earthed
using the correct clamp
secured to the chassis and an
adequately sized conductor.
4.
Fasten AC BUS cables
Fasten the AC BUS cable and
grounding wire to the frame
with cable ties.
Note: Be aware to keep the connectors in a position accessible to the AC cable
coming from the Microinverter.
5.
Connect AC cables
A.
Remove the temporary cap from AC BUS cable connectors and then connect
Microinverters;
B.
Protect any unused connectors by fitting AC trunk plug caps on them to keep
them watertight.

6.
Terminate the unused end of AC BUS cable
A.
Remove about 25mm(1.0’’) of the cable sheath from the conductors;
B.
Check that all connector parts are present, slide nut onto the cable and insert the
cable end through clamp ring and sealing ring;
C.
Insert every cable end to the hole with cable clamp of sealing cap tightly to make
them insulted;
D.
Screw nut to sealing cap with torque about 2.5Nm.
