2. Introduction
The monitoring system plays an important role in the PV plant. Users can view the PV
Plants power generation data and fault information to avoid unnecessary loss of
power and non-scheduled downtime. Users can also maximize the energy generating
efficiency according to power generating data and reports.
2.1 Product Overview
The AiCom/AiCom WiFi collects the inverter’s data and events in the PV plant. When
an Internet connection is present, the AiCom/AiCom WiFi will upload the collected
data to the AISWEI Cloud to facilitate on-line web monitoring and data analysis.
c
Fig.2-1: System structure
In the system structure shown in Fig. 2-1, the AiCom/AiCom WiFi connects to the

Installation
~ 9~
4. Installation
4.1 Location
The AiCom/AiCom WiFi should be installed indoors as extreme temperatures,
immersing in water, fire and strong impacts will damage the AiCom/AiCom WiFi.
To take advantage of the AiCom/AiCom WiFi´s self-powered feature the maximum
length of the RS485 cable between the AiCom/AiCom WiFi and the inverter is
20m.Should a separate power supply unit be used, the maximum length is then
increased to 1000m.
If the AiCom WiFi has the WiFi option, the antenna should be assembled as per Fig. 4-1.
Please ensure that the signal strength between the WLAN router and the AiCom WiFi is
strong enough to ensure a reliable wireless connection. Please refer to section 5.6 for
the WiFi setup instructions. If the AiCom WiFi is connected to the WLAN router, the
yellow WiFi LED will illuminate.
Fig. 4-1: Assemble the antenna
4.2 Installation
The AiCom/AiCom WiFi should be mounted on a wall as follows:
Step1: Select a suitable place for mounting.
Step2: Mark the positions of the drill holes on the wall (spacing of drill holes:
154mm).
Fig. 4-2: Mark the holes
Step3: Drill the holes (diameter: 6mm, depth: at least 30mm).
Step4: Remove dust that may have accumulated from the drill holes.

5.3 Connecting the Power
Requirements:
•Connect the RS485 cable directly to the AiCom/AiCom WiFi.
If the RS485 cable between the AiCom/AiCom WiFi and the inverter is more than
20m, a separate power supply unit is required.
Connect the power supply unit to the Power socket (Item A in Fig. 5-1). Plug the
other end into a power outlet, and check that the power LED light turns on as shown
in Fig. 3-1(LED indicator panel).
If a separate power supply unit is used, it must satisfy the following
requirements:
1. EMC directive and low voltage directive of the European
parliament.
2. Output voltage between 7.5Vdc and 12Vdcand output current at
least 500mA.
3. DC output polarity .
5.4 Connecting the Inverter
This section describes how to connect the AiCom/AiCom WiFi to the inverter(s):
Step 1: For PV Plants with more than one inverter, connect each inverter in a daisy
chain configuration, shown in Fig. 5-2, with the RS485 cable.
Step 2: Connect the inverter closest to the AiCom/AiCom WiFi to the RS485 port of
the AiCom/AiCom WiFi (Item B in Fig. 5-1) as shown in Fig. 5-2.
Fig. 5-2: Connection to the inverter

sure to use the correct port.
2. The maximum communication distance of the whole RS485 bus
is 1000m. Communication quality beyond this length is not
guaranteed and can also be influenced by the quality of the
RS485 cable.
5.5 Connecting the energy meter
AiCom/AiCom WiFi can connect to an energy meter for monitoring the exported
power of a PV plant, which can be used for active power limitation and zero export
function. The AiCom/AiCom WiFi currently supports the MINI POWER SDM630DC
EASTRON energy meter. For the energy meter wiring details please refer to the
SMART MIN POWER SDM630DC “USER MANUAL 2013 V1.1”.
The energy meter must be connected at the grid connection point, as shown in Fig. 5-
4.

5.6 Connecting to the Ethernet
The AiCom/AiCom WiFi requires an Internet connection in order to provide remote
monitoring. The connection between the AiCom/AiCom WiFi and the Internet is
shown in Fig. 5-8.
The AiCom/AiCom WiFi uses port #1883and #80 to communicate
with the AISWEI Cloud. Both of these two ports must be opened
otherwise the AiCom/AiCom WiFi cannot connect to the AISWEI
Cloud and upload data.
Fig. 5-8: Network connection
The AiCom/AiCom WiFi is connected to the network by simply connecting the
network cable from the router to the Ethernet port of AiCom/AiCom WiFi (Item D in
Fig. 5-1), as shown in Fig. 5-9.

Connection
~16~
Fig. 5-9: AiCom/AiCom WiFi linked network
The AiCom/AiCom WiFi obtains an IP address from the router via DHCP automatically
and displays it on the LCD. The time it takes to connect to the network depends on the
network communication conditions.
The router needs to support DHCP services therefore the DHCP
services must be activated.
If the IP address of the AiCom/AiCom WiFi is different from the
network segment assigned by the router,
Trouble shooting:
1. Make sure the DHCP service of router has been activated.
2. Check the connection between the AiCom/AiCom WiFi and the
router.
3. Check whether the AiCom/AiCom WiFi is using a fix IP address.
4. If the AiCom/AiCom WiFi cannot obtain an IP address from the
router, it will use 169.254.*.*(* symbol is a random number) as
the default IP address.

Connection
~ 17 ~
5.7 *Connecting to the WiFi
If users use the AiCom WiFi’s WiFi to connect to the router for remote monitoring, the
connection diagram is shown in Fig. 5-10.
Fig. 5-10: WiFi connection
In order to achieve remote monitoring reliably, the following steps must be taken.
Step1: Power on the AiCom WiFi and open the mobile device or laptop’s WLAN page
to find the AiCom WiFi’s wireless access point. The new access point of the AiCom
WiFi’s WiFi called AISWEI -XXXX is displayed, as shown in Fig. 5-11.Connect to the
access point using the mobile device or laptop and enter the password as “AISWEI”
when prompted.

1. "XXXX" stands for the last four digits in the serial number.
Step2: Start the web browser and enterhttp://160.190.0.1. The internal website
opens.

Connection

Step3: Select the wireless page and select a router in the [Wireless Network] area to
connect. The Password/Security Key dialog box opens, as shown in Fig. 5-12.
Fig. 5-12 connecting to wireless network
Step4: Enter the password of the wireless local network that you wish to connect to.
Do not enter the password of the router.
Step5: After approximately three minutes the WiFi of the AiCom WiFi will connect to
the wireless local network. The status indicator on the Wireless page should display
the icon and the yellow WiFi LED should now illuminate, as shown in Fig. 5-13.
