3.2 Identifying the Inverter
You can identify the inverter using the type label. Information such as serial number
(Serial No.) and type of the inverter, as well as device-specific characteristics are
specified on the type label. The type label is on the right side of the enclosure.
4 Mounting
DANGER!
Danger to life due to potential fire or electric shock.
Do not install the inverter near any inflammable or explosive items. The inverter will
be directly connected with high voltage power generation device. The installation
must be performed by qualified personnel only in compliance with national and local

4/ 15
standards and regulations.
CAUTION!
Danger of burns injuries due to hot enclosure parts.
•Install the inverter so that it cannot be touched inadvertently.
Risk of injury due to the heavy weight of the inverter.
•Take the inverter's weight of approx. 28 kg into account for mounting.
4.1 Selecting the Appropriate Mounting Location
Consider the following points when selecting where to install:
• The mounting method and location must be suitable for the inverter's weight and
dimensions.
• Mount on a solid surface. But do not mount the unit on plasterboard walls or
similar in order to avoid audible vibrations for the inverter can make noises when in
use.
• Vertical installation or tilted backward by max. 30 degree is allowed.
• Never mount the device with a forward tilt, horizontally or even upside down
• For the convenience of checking the LCD display and possible maintenance
activities, please install the inverter at eye level.

• The ambient temperature of installation site should be between -20 °C and +55 °C
(between -4 °F and 131 °F).
• Install the inverter directly exposes to strong sunshine is not recommended, the

5/ 15
excess heating might lead to power reduction.
• Provide better ventilation for the inverter to ensure that the heat is dissipated
adequately.
•The site altitude of installation should be below 1000m above sea level; more than
1000m above the sea level will cause derating.
4.2 Mounting the Inverter with Wall Mounting Bracket
1. Use the wall mounting bracket as a drilling template and drill the holes for the
screws.
2. Fix the wall mounting bracket to the wall using appropriate screws (diameter min.
6 mm, max. 8 mm) and washers (outer diameter min. 12 mm, max. 24 mm).
3. Hang the inverter to the mounting bracket and ensure the slot is fitted on the
bracket.
4. Check to ensure the inverter is correctly seated. Make sure to lock the inverter
with the safety-lock screws on both sides. Refer to the figure below.

5 Electrical Connection
Notes:
1. After the inverter has been installed in its fixed position, the electrical
connection to the unit can be established.
2. Make sure Max. Open Voltage and short-circuit current of the each PV strings
accord with the Spec.
3. Choose the appropriate cable width for AC/DC wire.
4. To connect the inverter, the AC and DC sides must be disconnected from all
power sources and secured against being inadvertently switched back on.
5. Before connecting the inverter to PV arrays and public grid, make sure the
polarity is correct.
5.1 Overview of the Connection Area

(VAC).
2. Disconnect the circuit breaker between the inverter and the grid.
3. Connect AC cable as follows:
Insert the sealing ring (D) into the threaded sleeve (C)
Thread the clamping nut (E) and the threaded sleeve (C) over the AC cable and
its order is shown in the figure below.

According to polarities, insert the grounding conductor PE (green-yellow) in the
screw terminal with the earth sign on the socket screw; the neutral conductor
N (blue) in the screw terminal N on the socket element; and phase L (brown or
black) into the screw terminal L on the socket element then tighten the screw
to make sure the wires are securely connected.

5.4 Communication
Communication through RS485
There are 2 slots for the communication connection area at the bottom side of the
HNS series inverters.
Note: The upper slot is optional and blocked as factory default.
Socket for the RS485 connection plug, there are 4 pins in it, as shown in the figure,
and them are defined as follows:
1
+5V
2
485+
3
485-
4
GND
Pin 1 is only used when communication is realized through wireless communication
module. Connect Pin 2, Pin 3 and Pin 4 if communication is realized through RS485.
RS485 can be used for multipoint communication. Up to 31 inverters can
communicate and be monitored through one communication module.
RS485 communication module and receiver can be purchased from Afore New
Energy as options. And relevant monitoring software can be downloaded from
www.aforenergy.com.

7 System Diagram
The typical connection diagram for the entire PV system is shown in the following
figure.
1. PV Panel: Provide DC power to inverter
2. Inverters: Converts DC (Direct Current) power from PV panel(s) to AC (Alternating
Current) power. Because Inverter is grid-connected it controls the current amplitude
according to the PV Panel power supply. Inverter always tries to convert the
maximum power from your PV panel(s).
3. Connection system: This “interface” between Utility and PV-Inverter may consist of
electrical breaker, fuse and connecting terminals. To comply with local safety

14 / 15
standards and codes, the connection system should be designed and implemented
by a qualified technician.
4. Utility: Referred to as “grid” in this manual, i.e. the way your electric power
company provides power to your place. Please note that Inverter can only connect to
low-voltage systems (namely, 220, 230VAC, 50Hz).
