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
ZeverCloud 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.

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
ZeverCloud. Both of these two ports must be opened otherwise the ComBox
cannot connect to the ZeverCloud 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.

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 can regulate the power of the inverter according to the value of
installed inverter capacity or the energy meter reading, which are set by the
user.
a) Active Power Limit
Tick “Active Power Limit” and fill in the total Inverter AC capacity to active Power
limit function. There are three modes of active power limitation which can be
selected.
1. Please make sure the inverter AC capacity is correct,
otherwise the power limitation function cannot work
properly.

Fig. 5-5: Set Active Power Limitation Method
The following ways will introduce how to configure the three kinds of power
limitation.
For correct operation of this method the parameter: tem A – total inverter AC
capacity of PV system that must be entered, please refer to Fig. 5-6:
Based on the Installed Inverter AC Capacity
In this method the AC output of the PV system will not exceed a set percentage
of the installed inverter AC capacity. For example, if a 20 % limitation on a 3
kWp PV system connected to an Zeverlution 3000S has been set then the AC
output will not exceed 0.6kWac.
Click the “OK” button in bottom-right of this web page to ensure the setting
parameters take effect.

Power Limitation Based on the Energy Meter Reading
In this method the export power of the PV system at the point of connection will
not exceed the set value. For example, if 0 kWac export limit has been set in
“limit output power based on the energy meter reading ” then a 3 kWp PV
system connected to zeverlution 3000S(3 kWac inverter) will reduce its AC
output power to ensure the export power at the smart meter won’t exceed 0
kWac.
Example for 0-export setting:
Please make sure all wire connection is correct before doing the settings on
web server.
Step 1: Tick “Active Power Limit” and fill in the total Inverter AC capacity to active
Power limit function.
Step 2: Select “limit output power based on the energy meter reading” and set
out put power<=0W
Step 3: Select the correct smart meter of the PV sysem
Setp 4: Click the “OK” button in bottom-right of this web page to ensure the
setting parameters take effect.
The PV system will automatically to regulate inverter’s output power to make
sure inverter’s output power won’t exceed the load power, in this case, no PV
power can feed into the grid.
