3.3 Equipment Installation
3.3.1 Selecting the installation position
Installation position should be selected based on the following
aspects:
The installation method and mounting location must be suitable
for the inverter's weight and dimensions.
Mount on a solid surface.
Select a well ventilated place sheltered from direct sun radiation.
Install vertically or tilted backward by max 15°. The device
cannot be installed with a sideways tilt. The connection area
must point downwards.

Figure 3.3.1-1

In consideration of heat dissipation and convenient
dismantlement, the minimum clearances around the inverter
should be no less than the following value:
Upward . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 300mm
Downward . . . . . . . . . . . . . . . . . . . . . . . . . . . . 500mm
Front . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 300mm
Both sides . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 200mm

3.3.2 Mounting Procedure
AUse the wall-mounted bracket as a template and drill 7 holes
on the wall, 10 mm in diameter and 80 mm deep.

BFix the wall mounting bracket on the wall with the expansion
bolts in accessory bag.
CCarry the inverter by holding the groove on the heat sink.
Figure 3.3.2-2
DPlace the inverter on the wall-mounted bracket (as illustrated
below).

3.4 Electrical Connection
The inverter is compatible with RCD and RCM.

- 10 -
The DC component may produce electricity; as a result, a residual
current operated protective (RCD) or monitoring device (RCM)
will be used for protection in case of direct or indirect contact, only
Type B RCD/RCM is allowed to be connected to the supply side of
the product.
3.4.1 Connection to grid (AC side Connection)
ACheck the grid (utility) voltage and frequency at the
connection point of the inverter. It should be 230VAC (or
220VAC), 50/60Hz, and single phase.
BDisconnect the breaker or fuse between PV-Inverter and utility.
CConnect the inverter to the grid as follows:
Switch off the AC Breaker.
Disassemble female connector of the AC wire connector
and connectAC wires to connection socket as indicated.
Figure 3.4.1-1
Insert Line wire to Pin 1, Neutral wire to Pin 2 and Ground
wire to Pin

3.4.2 DC side connection
AMake sure the maximum open circuit voltage (Voc) of each PV
string does not exceed the inverter input voltage Vmax under
any condition.
BUse Multi-contact connectors for PV array terminals.
CConnect the positive and negative terminals of the PV panel to
corresponding terminals on the Inverter. The DC terminal on
each Inverter can bear 20ADC current.

- 13 -
Female side connector (PV+) Male side connector (PV-)
both types of connectors must be equipped in pair strictly
according to above graphs

- 14 -
Figure 3.4.2-1 Separated by Ring tool
Before connecting the PV panels, please ensure the plug
connectors have the correct polarity. Incorrect polarity
connection could permanently damage the unit.

- 15 -
Checks short-circuit current of the PV string. The total short-
circuit current of the PV string cannot exceed the inverter’s
maximum DC current.
High voltage exists when the PV panel is exposed to the sun.
Please secure the terminal connection, and do NOT touch any
exposed components in case of electric shock.
3.4.3 RS485 Communication
RS485 interface is used for multipoint communication. EzLogger
can monitor and communicate with 50 inverters at the same time.
But the maximum length of the cable should not exceed 1000 m.
All the inverters, which communicate through one cable, should
use provided RS485 interface (a piece of 10# cable is recommend
to be connected for waterproofing without RS485 cable
connection). The typical inverter connection graph through RS485
is shown below.
Figure 3.4.3-1

- 16 -
The graph below shows the monitoring system connection, in
which inverters’ multipoint communication can be realized
through RS485 interface. The software “EzExplorer” used in PC
end can realize real-time monitoring of 16 EzLoggers at the same
time.

AConnection procedure:
a. Screw off the RS485 cover;
b. Remove the screw cap of the cable gland;
c. Remove one-hole sealing ring;
d. Put RS485 cable through the components in this order:
screw cap, one-hole sealing ring, gland body;
e. Compress the crystal head and insert it into corresponding
interface;
f. Fasten the waterproof of RS485 Cover;
g. Fasten the screw cap of the cable gland.
Figure 3.4.3-3

BRS485 cable is composed by eight wires with different colors.
Chop the envelope outside to expose the eight wires, then
straighten the end of every wire, and put them in order.
Figure 3.4.3-4
CThe connection between crystal connectors and RS485 wires
must be corresponding with each other, as shown in the table
below.
Figure 3.4.3-5
DPlug the eight wires into corresponding slots of the crystal
connector, and then fix them up using special tool below.
