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)

Page 6

1 InstallationandConnection User Manual

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.

Page 7

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.

Page 8

1 InstallationandConnection User Manual

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.

2.3 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”.
