1 InstallationandConnection
1.1 Connecting the eShow to the Inverter
The eShow is installed onto the inverter by means of the bracket and the M4 screw
in the packaging.
Fig. 1-1 Dimensions of the Bracket (unit: mm)
Fig. 1-2 Dimensions of the Fastener (unit: mm)

Procedure
Step 1 Secure the bracket to the inverter with the supplied screws and then hang
the eShow onto the bracket.
The eShow can also be mounted to the wall next to the inverter.
Make sure that the space between the eShow and the inverter is proper
for the cable connection.
Step 2 Connect the RJ45 plug to the RJ45 port on the bottom of the inverter. Fasten
the screws on the RJ45 plug.
Do not extend the communication cable. The loss of any or all rights may
follow if otherwise.
1.2 Connecting the eShow to the DRED
The eShow provides a DRM (Demand Response Mode) port for connecting to a
demand response enabling device (DRED). The DRM port is a standard Ethernet
port.

User Manual 1 InstallationandConnection

The following figure shows the DRM mode and the corresponding shorting pins of
the RJ45 plug.
The components of the DRM connector are included in the delivery scope, as shown
in the following figure.
Fig. 1-3 DRM Connector Components
* The seal and the support are not closed. So, you can use the standard network
cable with the RJ45 plug to assemble the DRM connector.
Procedure
Step 1 Lead the network cable through the components according to the following
sequence.
The seal and the support can be opened to place the cable body.
Align the RJ45 plug and the slot to lead the cable through the housing.

Step 2 Push the support and the seal into the housing. Then tighten the sealing nut
to the housing.
Step 3 Align the DRM connector and the DRM terminal on the eShow. Plug the
connector and make them engage perfectly.
Step 4 Tighten the screw nut of the connector to the DRM terminal.

2.1 Description of Button Function
Inverter offers two buttons for users to look up the running information and
configure parameters. The two buttons have multiple functions. Please refer to Tab.
2-1 before any operation of the inverter.
Please wait about 15s for eShow startup after completing the
connection.

2.3 Main Screen
The LCD display will enter the main screen after successful commissioning, as shown
in Fig. 2-2.
Fig. 2-2 Main screen
Tab. 2-2 Description of the main screen
Status Description
Run
After being energized, inverter tracks the PV arrays’ maximum power
point (MPP) and converts the DC power into AC power. This is the
normal operation mode.
Standby
Inverter enters Standby mode when DC input is insufficient or with the
DRM0 command from the DRED. In this mode inverter will wait within
the Standby duration (set by user, refer to “2.9 Setting the Running
Parameters”).
Stop Inverter is stopped.
Key-stop
Inverter will stop running by manual “stop” via the LCD menu. In this
way, inverter internal DSP stops. To restart the inverter, manually start
via the LCD menu.
Startup The inverter is initializing and synchronizing with the grid.
Dispatch Inverter output power can be adjusted via the LCD menu. The value of
Pac limit is lower than 100%.
Derating
Output derating is a way to protect the inverter form overload or
potential faults.
Situations require inverter power derating are too high internal
temperature, too low grid voltage and so on.
Fault ххх
If a fault occurs, inverter will automatically stop running, disconnect the
AC relay, and display the fault information on the LCD display with the
“FAULT” indicator on. “ххх” is the fault code, e.g. “010”.
Once the fault is removed in recovery time (set by user, refer to “2.9
Setting the Running Parameters”), inverter will automatically resume
running.
Warn ххх Warning information is detected. “ххх” is the warning code, e.g. “070”.

If a DRED is connected to the eShow and the
DRED activates a DRM command, the DRM
state will be shown on the main screen, as
shown in the figure.
Tab. 2-3 Demand Response Modes (DRMs)
Mode Explanation
DRM0 The inverter is in the state of standby.
DRM5 The export power to the grid is 0%.
DRM6 The export power to the grid is no more than 50% of the rated power.
DRM7 The export power to the grid is no more than 75% of the rated power.
DRM8 The export power to the grid is 100%, but subject to the constraints from
other active DRMs.
Viewing Current Fault
If inverter is in “Fault
”
state, touch to
view “Current fault” information. To know
the meaning of the fault code, please
refer to “3.1 Troubleshooting”.
2.4 Contrast Adjustment
Step 1 Press/touch on the main screen to enter the contrast adjustment screen.
Step 2 Touch to increase the setting value and touch to decrease the value.
Step 3 Press to confirm the contrast setting.
Contrast adjustment range: 0…100%
Recommended value: 50% or 60%.
