2. FCC COMPLIANCE
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protecn against harmful interference in a residenal installan. This equipment generates
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instrucns, may cause harmful interference to radio communicans. However, there is
no guarantee that interference will not occur in a parcular installan. If this equipment
does cause harmful interference to radio or television recepn, which can be determined by
turning the equipment oand on, the user is encouraged to try to correct the interference by
one or more of the following measures:
●Reorient or relocate the receiving antenna.
●Increase the separan between the equipment and the receiver.
●Connect the equipment into an outlet on a circuit dierent from that to which the
receiver is connected.
●Consult the dealer or an experienced radio/TV technician for help.
Changes or modicans not expressly approved by the party responsible for compliance may
void the user’s authority to operate the equipment.

4.3 Energy Funcns
A menu bar locates on the top of the screen. Dierent screen pages on energy and power
can be called by pressing on these menu buons.
4.3.1 Tay’s Energy
Pressing this buon will display the power-me curve screen (seeFigure 5). The x-axis
represents the me (4:00-20:00), and the y-axis represents NEP micro inverters (BDM-250)
output power (kW). The total output energy (kWh) is displayed on the upper lecorner. The
real-me output power (kW) and today's total energy generated (kWh) are displayed on the
upper right corner. Part of the curve can be magnied by drawing a box on the curve using
nger or touch pen. Pressing the Today's Energy buon again cancels the enlarged display
and restores the original display.
Figure 5 Today’s Power
Figure 6 Drawing a box on Today’s Power
4.3.2 Last 7 Days’ Energy
Pressing this buon will bring up a bar chart showing power generaon 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) on the day.
Figure 7 Last 7 Days’ Energy
4. USER INTERFACE
4.1 Main Interface
BDG-256/BDG-256P3 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 (all three
numbers will read “0” at start-up for the rst me).
Figure 3 BDG-256/BDG-256P3 Main Display
Figure 3shows the BDG-256/BDG-256P3 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n), 7-Day's Energy (power generan over the
past 7 days), Monthly Energy (power generaon over each month), Yearly Energy (power
generan 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n bar chart. The status bar shows the device status,
IP address, and current date.
4.2 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 screen 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n since device started recording), and the lower lecorner shows CO2 reducn
(reducn in carbon dioxide emissions). Touching any part of the screen will bring up the main
interface.

4.4.2 Date & Time Seng
The Date & Time sengs tab (Figure 11) is used to set the date, me, and me zone. BDG-256
supports all ve me zone of North America. For other parts of the world, the me zone “World”
may be chosen.
Figure 11 Date & Time Seng
4.4.3 CmmunicaAddress Seng
The communicans address sengs tab (Figure 12) is used to set the power line communican
address of the micro-inverters linked to the device. One BDG-256 gateway can monitor up to 255
micro inverters.Inverter-0 on the address list corresponds to the total output of all inverters
connected to the gateway
Address sengs can be input using either the small input panel on the touch-screen or an external
USB keyboard. The communican address of a micro inverter consists of the 8 hex characters (0~F)
on the BDM micro inverter bar code before the last leer for country. Another way to input the
micro inverter communican address is through an internal web portal (see Secn 5).
Figure 12Communican Address Seng
4.5 Backup/Clear Data
When a USB ash disk is inserted, press the Save/Clear buon to call up the following dialog box
(see Figure 13).
4.3.3 Mnthly Energy
Pressing this buon will bring up a bar chart showing power generanover 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 on the last. The y-axis represents the
amount of energy generated (kWh) in the month.
Figure 8Monthly Energy
4.3.4 Lifeme Energy
Pressing this buon brings up a bar chart showing power generan 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 on the last. The y-axis represents the
amount of energy generated (kWh) in the year.
Figure 9 Yearly Energy
4.4 Seng
Pressing the Seng buon will bring up the sengs dialogs.
4.4.1 IP Seng
BDG-256's IP address may be manually set in the Ethernet sengs tab (Figure 10). They may
also be obtained through DHCP (requires a system restart aer seng). If the IP address
must be changed, double click on the address box to bring up a small keypad on the screen.

Figure 13 Backup/Clear Data
Press the Save buon, and press “Yes” in the conman window that appears to compress
and backup all collected data to the USB ash disk. The document will automacally use the
backup date for its name.
Press the Reset buon, and press Yes in the conman window that appears to clear all
collected data. The device sengs will not be changed.
4.6 Status Bar
The boom eld 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n. The meaning of the error code is listed in
the following table.
Error code Error

5. WEB INTERFACE
The BDG-256/BDG-256P3 informaon can be accessed through two web pages. The st one is a
web server inside the BDG-256/BDG-256P3 gateway. The second one is a web server provided by
NEP, which access requires internet service.
MICROVIEWER mnitring w/ built-in BDG-256/BDG-256P3
The local web portal built inside BDG-256/BDG-256P3 can be accessed through home network
without internet service. If there is internet service, however, remote monitoring can be accessed
through NEPVIEWER from anywhere at anyme
To access the web portal inside BDG-256/BDG-256P3, user only needs to type in the IP address of
BDG-256/BDG-256P3 on a web browser. (Please see Secon 4.4.1 for conguring the IP address of
BDG-256/BDG-256P3). The administran page for inverter address can be accessed by
hp://GATEWAY-IP/module (for example hp://10.208.100.202/module)
