Ethernet cable is used to connect the HY-MDL/HY-MDL-3 to an Ethernet router or hub. There is a web server built
inside HY-MDL/HY-MDL-3, which can be visited by type in the HY-MDL/HY-MDL-3 IP address on a web browser.
If the HY-MDL/HY-MDL-3 is connected to the internet directly or through a router, users may also visit the
HY-MDL/HY-MDL-3 through a website.
USB devices can be connected to the HY-MDL/HY-MDL-3 through the USB connector. Multiple types of USB
devices are supported by HY-MDL/HY-MDL-3, including USB disk, USB keyboard, USB mouse, USB scanner, etc.
HY-MDL/HY-MDL-3 takes approximately 1-2 minutes to start up after power has been turned on. After start-up,
the system will enter the main interface as shown in Figure 3 (all three numbers will read “0” at start-up for the
first time).
Figure 3 shows the HY-MDL/HY-MDL-3 main interface. The main interface is arranged in three horizontal rows,
which consist of the tool bar at the 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.
If the main interface is idle for 2~3 sec., it will switch to a numeric summary interface, which is described as below:
The screen 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 CO2 reduction (Reduction In Carbon Dioxide Emissions). Touching any part of the screen will bring up the
main interface.

4.3 Energy Functions
A menu bar locates on the top of the screen. Different screen pages on energy and power can be called by
pressing on these menu buttons.
Pressing this button will display the power-time curve screen (see Figure 5). The x-axis represents the time
(4:00-20:00), and the y-axis represents Huayu micro inverters output power (kW). The total output energy (kWh)
is displayed on the upper left corner. The real-time output power (kW) and today's total energy generated (kWh)
are displayed on the upper right corner. Part of the curve can be magnified by drawing a box on the curve using
finger or touch pen. Pressing the Today's Energy button again cancels the enlarged display and restores the
original display.

4.3.2 Last 7 Days’ Energy
Pressing this button will bring up a bar chart showing power generation over the past 7 days (see Figure 7). The
x-axis represents the date and the last one corresponds to today. The y-axis represents the amount of energy
generated (kWh) during the day.
4.3.3 Monthly Energy
Pressing this button will bring up a bar chart showing power generation over each month for the last 12 months
(see Figure 8). This display is similar to the Last 7 Days' Energy display. The x-axis represents months and the
current month is in the last. The y-axis represents the amount of energy generated (kWh) in the month.
4.3.4 Yearly Energy
Pressing this button brings up a bar chart showing power generation over each year for the past 20 years (see
Figure 9). This display is also similar to the Last 7 Days' Energy display. The x-axis represents the years and the
current year locates in the last. The y-axis represents the amount of energy generated (kWh) in the year.

Pressing the Setting button will bring up the settings dialog.
HY-MDL/HY-MDL-3's IP address may be manually set in the Ethernet settings tab (Figure 10). They may also be
obtained through DHCP (requires a system restart after setting). If the IP address must be changed, double click
on the address box to bring up a small keypad on the screen.
4.4 Setting
4.4.1 IP Setting
The Date & Time settings tab (Figure 11) is used to set the date, time, and time zone. HY-MDL/HY-MDL-3 support
all the five time zone of North America. For other parts of the world, the time zone “World” may be chosen.
The communications address settings tab (Figure 12) is used to set the power line communication address of the
micro inverters linked to the device. One HY-MDL/HY-MDL-3 monitoring data logger can monitor up to 255 micro
inverters. Inverter-0 on the address list corresponds to the total output of all inverters connected to the monitoring
data logger.
Address settings can be input using either the small input panel on the touch-screen or an external USB keyboard.
The communication address of a micro inverter consists of the 8 hex characters (0~F) on the Huayu micro inverter
bar code before the last letter for country. Another way to input the micro inverter communication address is through
an internal web portal (see Section 5).

The HY-MDL/HY-MDL-3 information can be accessed through two web pages. The first one is a web server
inside the HY-MDL/HY-MDL-3 monitoring data logger. The second one is a web server provided by Huayu,
which access requires internet service.
The local web portal built inside HY-MDL/HY-MDL-3 can be accessed through home network without internet
service. If there is internet service, however, remote monitoring can be accessed through Huayu Portal from
anywhere at anytime.
To access the web portal inside HY-MDL/HY-MDL-3, user only needs to type in the IP address of HY-MDL/HY-
MDL-3 on a web browser (please see Section 4.4.1 for configuring the IP address of HY-MDL/HY-MDL-3).
The administration page for inverter address can be accessed by http:/…/module.cgi (for example http://10.
