Step3- Input micro inverter’s ID to the MRG
Click the COM ID buon, input sequenally each micro inverter’s ID. You can find a bar code
scker at the boom of the micro inverter, below the bar code there is an alphanumeric string, in
which eight shows micro inverter’s ID, for example: 21211-0000B123A, the part of 0000B123 is
the ID of micro inverter, but you just need to input B123 into the Module ID. You need to start the
input from the Module1 ID.
There are two methods of input:
Pop-up so keyboard on the interface.
You can add an external USB keyboard.you must connect the keyboard to MRG by USB interface
first, and then restart the MRG.Aer restart, you can use it.
Step4- Network sengs
Click the Ethernet buon for the network sengs, you can manually set the IP address and you
can also choose to get automacally by DHCP way.
Step5- Date&Time sengs
Click the Date&Time buon to set the me, date and me zone
Step6- Save and restart
Click OK buon, the need to reboot will be displayed on the interface, click OK buon to restart
the interface. Reboot completed, enter Today’s Energy, if micro inverter operates normally, the
power data will be displayed.
The MRG takes approximately 1-2 minutes to start up aer power has been turned on. Aer
start-up, the system will enter the main interface shown in Fig. 3.1 (all three numbers will read
“0” at start-up).
Fig. 2 shows the MRG main interface. The main interface is arranged in three horizontal rows,
which consist of the tool bar at the very top, the display area in the middle, and the status bar at
the lower part of the screen. The tool bar contains 7 buons: Save/Clear (backup/restore factory
defaults), Summary Display (summary display interface), Today's Energy (current day power
generaon), 7-Day's Energy (power generaon over the past 7 days), Monthly Energy (power
generaon over each month), Yearly Energy (power generaon over each year), and Sengs.
These buons are used to display their respecve content in the middle display area. The display
area shows the power-me curve for the current day as well as a power generaon bar chart. The
status bar shows the device status, IP address, and current date.

Last 7 Days' Energy: Pressing this buon will bring up a bar chart showing power generaon over
the past 7 days (see Fig. 3.4). Here the horizontal coordinates represent the date (in Fig. 3.5,
today is Thursday October 25, and Wednesday (yesterday),Tuesday (day before yesterday),
Monday, Sunday, Saturday, Friday, and Thursday are shown from le to right), and the vercal
coordinates represent power generaon (kWh). The green bar represents the amount of
generated power. The absence of a green bar means that no power was generated on that day, or
that there was no power-generaon recorded for that day.
Monthly Energy: Pressing this buon will bring up a bar chart showing power generaon over
each month for the last 12 months (see Fig. 3.6). This display is very similar to the Last 7 Days'
Energy display. Here the horizontal coordinates represent the month (in Fig. 3.6, today is October
25, and September (September of this year), August (August of this year), July… November, and
October (October of last year) are shown from le to right), and the vercal coordinates
represent the amount of power generated (kWh). The green bars indicate the amount of power
generated over each month. The absence of a green bar means that no power was generated
that month, or that there was no power-generaon recorded for that month.
Yearly Energy: Pressing this buon brings up a bar chart showing power generaon over each
year for the past 20 years (see Fig. 3.7). This display is also very similar to the Last 7 Days' Energy
display. Here the horizontal coordinates represent the year (the years 2011, 2010… are shown
from le to right), and the vercal coordinates represent the amount of power generated (kWh).
The green bars indicate the amount of power generated over each year. The absence of a green
bar means that no power was generated that year, or that there was no power-generaon
recorded for that year.
The interface as a whole is divided into three parts. The upper part shows Today's Energy (current
day power generaon), the lower right corner shows Lifeme (total power generaon since
device started recording), and the lower le corner shows CO2 reducon (reducon in carbon
dioxide emissions). Touching any part of the screen will bring up the main interface.
3.2 Interface Overview

Today's Energy: Pressing this buon will display the power-me curve screen (see Fig. 3.3). Here
the horizontal coordinates represent the me (4:00-20:00), and the vercal coordinates
represent the power (kW). The red curve is the power generaon power-me curve of the
micro-inverter linked to the MRG. This curve is refreshed once per minute. The total generated
power (kWh) is displayed in the upper le corner, and the real-me power generaon rate (kW)
and today's total power generaon (kWh) are shown in the upper right corner. These figures are
refreshed once per second. Drawing a box around an area on the touch-screen will magnify the
boxed-in area of the power-me curve (see figures 4-5). Pressing the Today's Energy buon again
will cancel the enlarged display and restore the inial display status.

Pressing the Seng buon will bring up the sengs dialog, as shown in Figures 9-11.
The device's IP address may be manually set in the Ethernet sengs tab (Fig. 3.9). The subnet
mask and Ethernet Gateway (Gate) may also automacally obtain an Ethernet address via DHCP
(requires a system restart). If the IP address must be changed, click in the address box and click
again to call up a small input panel allowing the address to be modified.
The Date & Time sengs tab (Fig. 3.8) is used to set the date, me, and me zone. The device
currently supports only the six me zones covering the United States.
3.4 Sengs
When a USB flash disk is inserted, press the Save/Clear buon to call up the following dialog box
(see Figure 3.11).
Press the Save buon, and press Yes in the confirmaon window that appears to compress and
backup all collected data to the USB flash disk. The document will automacally use the backup
date for its name.
Press the Reset buon, and press Yes in the confirmaon window that appears to clear all
collected data. This is limited to power-generaon data; device sengs will not be changed.
3.5 Backup/Clear Date

The communicaons address sengs tab (Fig. 3.10) is used to set the powerline carrier
communicaons address of the micro-inverter linked to the device. Sengs can be input using
either the small input panel on the touch-screen or an external USB keyboard. You can find a bar
code scker at the boom of the micro inverter, below the bar code there is an alphanumeric
string, in which eight shows micro inverter’s ID, for example: 21211-0000B123A, the part of
0000B123 is the ID of micro inverter which consists of a 32-bit decimal number represented as a
hex number , but you just need to input B123 into the Module ID.The device can support a
maximum of 255 micro-inverters, but Module0 is the device's communicaons address and may
not be changed. Click in the address box, and click again to bring up a small input panel allowing
the address to be modified.
When finished inpung sengs, press OK (confirm) to bring up a restart prompt. Restart is not
required aer seng the me, but Ethernet and micro-inverter ID sengs will only be applied
aer a restart. When you press the OK (confirm) buon, the device will automacally restart. If
you press Cancel, the device will sll save the changed sengs, but will only apply those changes
aer the next restart.

The boom field on all display pages consists of the status bar, which displays the device's
operang status, the current IP address, and the current date and me. “OK” means that the
device is operang normally. A 16-bit error code will be displayed in the form of a hex number if
there happens to be a malfuncon.

This following table is the display on the status bar which each error occur separately.
If an IP address must be obtained automacally using DHCP, first insert the network cable and
select “DHCP” on the Ethernet sengs page (this works only when there is a DHCP server on the
network). Aer confirming the changes, restart the device; if successful, the IP address that has
been automacally obtained will be displayed in the status bar.
If you wish to use a USB keyboard for input, plug the keyboard’s USB cable into the device's USB
port, then restart the device. The device will automacally recognize the keyboard and allow it to
input data. If a keyboard is inserted but the device is not restarted, the device will not recognize
the keyboard.
Current-day power-me curve data and current-day power-generaon data are lost aer the
device is restarted, but power-generaon data history will remain on the device even aer a
restart.
