1 Installation
1.1 Location Requirements
The concrete wall should be suitable for the weight and dimensions of the
inverter.
The location should be convenient for installation, cable connection and service.
The location should be not accessible to children.
The location should be away from flammable materials or gas, and the
environment should not be enclosed.
Flammable wall Flammable material or
gas near the installation Closed Cabinet
The shaded side of the building would be better.

Install vertically for sufficient heat dissipation.
Clearance requirements for single and multiple installation:
1.2 Installing the Inverter
Install the inverter on the wall by means of the wall-mounting bracket and the
expansion plug sets.
The depth of the holes should be about 70 mm. Be sure to adhere to the following
screw assembly sequence: self-tapping screw, spring washer, fender washer,
wall-mounting bracket.
D70mm

1.3 Grounding the Inverter
A second protective earth (PE) terminal is equipped at the side of the inverter. Be
sure to connect this PE terminal to the PE bar for reliable grounding.
Fig. 1-1 Second PE Terminal
In no case shall the second PE connection substitute for the PE connection
on the terminal block of AC connector. Be sure to connect both PE terminals
for reliable grounding. The loss of any or all rights may follow if otherwise.

2.2 Meter Connection
The Sungrow single-phase energy meter is installed next to the main switch.
Procedure:
1.
T
ake out the meter (with
1-phase sensor) and the
cables from the packaging.
2. Connect the cables to the meter.
a) Tighten the power supply wires to
terminal 3 (L) and terminal 6 (N).
b) Tighten the RS485 wires to
terminal 2(A) and terminal 5 (B).
c) Place the 1-phase sensor around
the phase wire (L) from the main
switch.
The CT clamp of 1-phase sensor can be
placed before or after the main switch.

3. Proceed as follows to connect the RS485 wires to the inverter.
When the length of RS485 cable is longer than 100 m, push the 120ohM (2) switch
to “ON”to ensure stable communication
2.3 Grid Connection
Install an AC circuit breaker (recommended specification 32 A) between the inverter
and the loads.
Make sure to disconnect the AC circuit breaker and secure it against reconnection
before cable connection.

2.4 PV Connection
The inverter has two PV inputs and can be configured in the independent mode or
parallel mode. Refer to the user manual for mode selection.
Before connecting the PV arrays to the inverter, ensure that the impedances
between the positive terminals of the PV string and Earth, and between the
negative terminal of the PV string and Earth are larger than 200 kOhm.
The inverter will not function properly if the DC polarities are reversed.
Check the positive and negative polarities of the PV cells.
