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 report.
ComBox has two versions: ComBox and ComBox WiFi.
2.1 Product Overview
The ComBox is an integrated monitoring device, which can be installed inside the
inverter, and collects the inverter’s data and events in the PV plant. When an
Internet connection is present, the ComBox will upload the collected data to the
Solarcloud to facilitate on-line web monitoring and data analysis. The system
structure shows in Fig. 2-1.

3.2 Assembling the ComBox
3.2.1Electrical Checks
Risk of lethal electric shock when opening the inverter may cause death or
serious injury. Therefore before assembly, ensure that the inverter is isolated
from all sources of AC and DC power (see inverter Installation Guide).
Electrostatic discharge can damage the inverter. Please ground yourself before
touching components by touching the protective conductor (PE) or a non-coated
part of the inverter enclosure.
1. In order to ensure safety, before assembly, please
read the inverter user manual carefully.
2. Assembly is strictly prohibited when the inverter
connected to electricity or is in operation.
3.2.2 Assembly
For details regarding mounting please refer to the ComBox Quick Installation
Guide.

Connecting to the Internet
~ 7~
4. Connecting to the Internet
The ComBox requires an Internet connection in order to provide remote
monitoring via Ethernet or WiFi.
The ComBox uses network port #6655 and #80 to communicate with the
Solarcloud. Both of these two ports must be opened otherwise the ComBox
cannot connect to the Solarcloud and upload data.
If the IP address of the ComBox is different from the network
segment assigned by the router,
Troubleshooting:
1. Make sure the DHCP service of router has been activated if
ComBox use DHCP function.
2. Check the connection between the ComBox and the router.
3. Check whether the ComBox was using a fix IP address.
4. If the ComBox cannot obtain an IP address from the router,
it will use 169.254.1.100 or 0.0.0.0
4.1 Connecting via Ethernet
The ComBox is connected to the Ethernet by simply connecting the Ethernet
cable from the router to the Ethernet port. The connection between the ComBox
and the Internet is shown in Fig. 4-1.
Fig. 4-1: Network connection
The ComBox obtains an IP address from the router via DHCP automatically and
displays it on the LCD of the inverter. The time it takes to connect to the Internet
depends on the network communication conditions. At the same time the router
needs to support DHCP services and the DHCP services must be activated if the
ComBox has been set up to use the DHCP function.

Fig. 4-2: WiFi connection
In order to achieve remote monitoring reliably, the following steps must be
taken.
Step1: Power on the inverter, which will also power ComBox, and use a mobile
device or laptop to search for the wireless access point (AP) of the Combox WiFi.
A new AP of ZEVERSOLAR -XXXX is displayed, Select this AP to connect. The
password is “zeversolar”. As shown in Fig. 4-3.
Fig. 4-3 WiFi connection page
1. "XXXX" stands for the last four digits in the Registry ID of
the Combox.
Step2: Start the web browser and enter http://160.190.0.1. The internal website
opens.
Step3: Select the wireless page and select a wireless local network in the area
to connect. The Password/Security Key dialog box opens, as shown in Fig. 4-4.

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 one minute the WiFi of the ComBox will connect to
the wireless local network. The status indicator on the Wireless page should
display the icon, as shown in Fig. 4-5.

5. Web Server
The ComBox has an integrated internal web server. The running state of the
inverter can be checked from the internal web server page. You can also enable
some advanced functions such as output power limitation and adjusting the
inverters safety parameters
The interface structure of the built-in web server is shown in Fig. 5-1.
Fig. 5-1: Structure of the web server
5.1 Visiting the Web Server
There are two ways to visit the internal web server of the ComBox: via Ethernet
or via WIFI (if the ComBox is equipped with the WiFi module).
5.1.1 Visiting via Ethernet
Input the IP address of the ComBox (shown on the inverter’s LCD) in the
browser’s address bar. For example, if the IP address shown on the inverter is
192.168.10.13, then enter 192.168.10.13 in the browser’s address bar and press
the Enter key to open the web page, as shown in Fig. 5-2.
5.1.2*Visiting via WiFi
You also can visit the web page via WiFi, please refer to section 4.2. Once you
are wirelessly connected to the ComBox, input“160.190.0.1”in the browser’s
address bar, press the Enter key to display the internal web page of ComBox, as
shown in Fig. 5-2.

5.4 Advanced
The Advanced web page shows the advanced settings of the ComBox, Such as
the power management and safety setting.
In addition, the firmware of the ComBox and Inverter can be upgraded from this
webpage.
5.4.1 Power Management
The ComBox will regulate the active power of inverter according to value of the
installed PV module capacity or the installed inverter capacity or the energy
meter reading, which are set by the user. Enter the fit to values in Fig. 5-4.
a) Active Power Limit
There are two modes of active power limitation can be selected and five values
need to set.
Fig. 5-4: Set Active Power Limitation Method
The following ways will introduce how to configure the two types of power
limitation.

Web Server
~ 13 ~
Based on the installed Solar DC capacity
In this method the AC output of the PV system will not exceed a set percentage
of the installed solar DC capacity. For example, if a 20 % limitation on a 1,5 kWp
PV system connected to an Eversol TL2000 (2 kWac inverter) has been set then
the AC output will not exceed 1.2 kWac.
The Fig.5-5 shows the system diagram of power limitation based on the
installed solar DC capacity
Fig. 5-5 System diagram based on the installed solar DC capacity
For this method position 1 in Fig. 5-6 should be ticked.
For correct operation of this method there are three parameters that must be
entered, please refer to Fig. 5-6:
Item a –installed solar DC capacity of PV system in Wp;
Item b –total inverter AC capacity of PV system in W;
Item c –Limitation value of solar DC capacity in %.
Click “OK” button in bottom-right of this web page to ensure the setting
parameters take effect.
