1. Gateway Hardware Structure
Figure 1(a) Figure 1(a)
As shown in Fig. 1(b), the hardware reset button is on the left side of the device. Pressing this button will restart the system. A 10M/100M Ethernet port is located in the center. A USB port is located on the right, which allows the user to connect a USB flash disk, keyboard, or mouse.
2. Main System Interface
The MRG takes approximately 1-2 minutes to start up after power has been turned on. After start-up, the system will enter the main interface shown in Fig. 2 (all three numbers will read “0” at start-up).
Figure 2 MRG main system interface
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 buttons: Save/Clear (backup/restore factory defaults), Summary Display (summary display interface), Today's Energy (current day power generation), 7-Day's Energy (power generation over the past 7 days), Monthly Energy (power generation over each month), Yearly Energy (power generation over each year), and Settings.
These buttons are used to display their respective content in the middle display area. The display area shows the power-time curve for the current day as well as a power generation bar chart. The status bar shows the device status, IP address, and current date.

2.1 Interface Overview
If the main interface is idle for 2-3 sec., it will switch to a numeric summary interface, which is described below:
The interface as a whole is divided into three parts. The upper part shows Today's Energy (current day power generation), the lower right corner shows Lifetime (total power generation since device started recording), and the lower left corner shows CO
2
reduction (reduction in carbon dioxide emissions). Touching any part of the screen will bring up the main interface.

2.2 Energy Functions
Today's Energy: Pressing this button will display the power-time curve screen (see Fig. 4). Here the horizontal coordinates represent the time (4:00-20:00), and the vertical coordinates represent the power (kW). The red curve is the power generation power-time 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 left corner, and the real-time power generation rate (kW) and today's total power generation (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-time curve (see figures 4-5). Pressing the Today's Energy button again will cancel the enlarged display and restore the initial display status.

Last 7 Days' Energy: Pressing this button will bring up a bar chart showing power generation over the past 7 days (see Fig. 6). Here the horizontal coordinates represent the date (in Fig. 6, today is
Thursday October 25, and Wednesday (yesterday),Tuesday (day before yesterday), Monday,
Sunday, Saturday, Friday, and Thursday are shown from left to right), and the vertical coordinates represent power generation (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-generation recorded for that day.
Figure 6 Bar chart of power generation during past 7 days
Monthly Energy: Pressing this button will bring up a bar chart showing power generation over each month for the last 12 months (see Fig. 7). This display is very similar to the Last 7 Days'
Energy display. Here the horizontal coordinates represent the month (in Fig. 7, 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 left to right), and the vertical 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-generation recorded for that month.
Figure 7 Monthly power generation bar chart
03
Yearly Energy: Pressing this button brings up a bar chart showing power generation over each year for the past 20 years (see Fig. 8). 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 left to right), and the vertical 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-generation recorded for that year.

2.3 Settings
Pressing the Setting button will bring up the settings dialog, as shown in Figures 9-11.

Figure 11 Communications address settings tab
The device's IP address may be manually set in the Ethernet settings tab (Fig. 9). The subnet mask and Ethernet Gateway (Gate) may also automatically 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 settings tab (Fig. 10) is used to set the date, time, and time zone. The device currently supports only the six time zones covering the United States.
The communications address settings tab (Fig. 11) is used to set the powerline carrier communications address of the micro-inverter linked to the device. Settings can be input using either the small input panel on the touch-screen or an external USB keyboard. Just input the final four digits or character string of the micro-inverter's shell address (the address format consists of a 32-bit decimal number represented as a hex number). The device can support a maximum of
255 micro-inverters, but Module0 is the device's communications 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 inputting settings, press OK (confirm) to bring up a restart prompt. Restart is not required after setting the time, but Ethernet and micro-inverter ID settings will only be applied after a restart. When you press the OK (confirm) button, the device will automatically restart. If you press Cancel, the device will still save the changed settings, but will only apply those changes after the next restart.

3. Backup/Clear Data
When a USB flash disk is inserted, press the Save/Clear button to call up the following dialog box
(see Figure 13).
06
Figure 13 Clear backup data
Press the Save button, and press Yes in the confirmation window that appears to compress and backup all collected data to the USB flash disk. The document will automatically use the backup date for its name.
Press the Reset button, and press Yes in the confirmation window that appears to clear all collected data. This is limited to power-generation data; device settings will not be changed.
4. Status Bars
The bottom field on all display pages consists of the status bar, which displays the device's operating status, the current IP address, and the current date and time. “OK” means that the device is operating normally. A 16-bit error code will be displayed in the form of a hex number if there happens to be a malfunction.
5. Other Important Items and Procedures
If an IP address must be obtained automatically using DHCP, first insert the network cable and select “DHCP” on the Ethernet settings page (this works only when there is a DHCP server on the network). After confirming the changes, restart the device; if successful, the IP address that has been automatically 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 automatically 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-time curve data and current-day power-generation data are lost after the device is restarted, but power-generation data history will remain on the device even after a restart.
