Introduction
1.0 Introduction
The MagWeb GT (ME-MGT-MW) is the information gateway for our
MicroGT 500 microinverters. The unit collects module performance
data and transfers this information to an Internet database in real
time (retains data for the last 30 days), requiring only a single data
and power cable.
The MagWeb GT’s integrated http web server offers the simplest
and most flexible network integration of any data logger on the
market. The user-friendly browser-based interface lets you access
your solar array in seconds.
The MagWeb GT monitors the microinverters that are connected to
the PV modules. Therefore, the communication between inverters
and the MagWeb GT does not affect inverter performance, even if the
MagWeb GT fails to communicate with the inverters. The MagWeb
GT is NOT a revenue grade metering device. Power production data
collected by the MagWeb GT is for reference only. Check your utility
meter for the real power production of the whole system.
1.1 System Features
• Collects individual module and microinverter statistics
• Communicates in real time
• Requires no additional wiring
The MagWeb GT monitoring system is used in utility-interactive
grid-tied applications, and includes two key elements (Figure 1):
• Magnum Energy MicroGT 500 microinverter(s)

Introduction
Power Connection Port:
The Power Connection port is used to supply the MagWeb GT with
power and to communicate with the microinverters using the Power
Line Communications (PLC) protocol.
MagWeb GT Serial Port:
The RS232 serial port is used to connect the MagWeb GT to a
Magnum pure sine inverter.
Note: You must purchase Magnum’s RJ11-DB6 adapter (ME-
MGT-ADAPTER)—includes a DB9 M-F Extension cable (1’) and
25’ (RJ11) remote cable—to connect the MagWeb GT to the pure
sine inverter. Refer to the ME-MGT-ADAPTER Instruction Sheet
(PN:64-0088) for information on making this connection.
Network Port (RJ45):
The Network port (RJ45) is used to connect the MagWeb GT to your
local network via a CAT5 cable. This port can be used as a direct
connection to the network router, or as an indirect connection that
goes through a Wi-Fi extender or PLC bridge.
USB Port:
The USB port can be used as a power source (5VDC) for a Wi-Fi
bridge, if necessary. It is NOT a two-way communication port, and
is therefore incompatible with external Wi-Fi devices such as Wi-Fi
dongles or thumb drives.
Reset Slot:
The Reset button is used to return the MagWeb GT to its default
settings—press and hold for 3 seconds or longer.
Note: The historical power generation will not be cleared when the
Reset button is pushed.
1.2 Interface Features
The MagWeb GT interface includes: Power Connection port, MagWeb
GT Serial port, Network port, USB port, and a Reset slot (Figure 2).

Installation
2.0 Installation
2.1 Pre-Installation
Carefully remove the MagWeb GT from its shipping container and
inspect all contents. Verify the following items are included:
• MagWeb GT • MagWeb GT Owner’s Manual
• Power cable (115 VAC) • CAT5 Network cable (RJ45)
Make sure you have access to the following before attempting to
install the MagWeb GT:
• A dedicated standard AC electrical outlet.
• An available broadband Internet connection.
• A broadband router with a CAT5 Ethernet, or wireless router.
• A pre-programmed MagWeb GT unit.
2.2 Selecting a Location to Install the MagWeb GT
Find a location that is located as electrically close to the solar sub-
panel as possible on a dedicated circuit—this enhances the Power
Line Communications (PLC) signal.
Note: Locating the MagWeb GT at or very near the solar sub-panel
may not be the most convenient location, but it ensures a clean PLC
signal and a stable data stream.
The MagWeb GT is NOT rated for outdoor use, so if installing outdoors
near a junction box or breaker panel make sure that you enclose it
in an appropriate weatherproof NEMA electrical box (PN: MP-ODE).
2.2.1 Using an Electrical Mounting DIN Rail
1. Loosen the two M3 mounting screws on the back of the MagWeb
GT, and then rotate the two rail holders so that the holders are
above the unit (Figure 3).

sized screws (Figure 4).
Figure 5, Wall Mounting the MagWeb GT
2.2.2 Using a Wall Mount
When mounting the MagWeb GT on a wall, make sure to select a
cool, dry, indoor location.
1. Depending on the wall surface to which you are mounting the
MagWeb GT, use either two #8 drywall screws or two wall
anchors—installed 5.1” (130 mm) apart. The drywall screws and
wall anchors are NOT supplied with the MagWeb GT.
2. Align/slide the MagWeb GT onto mounting screws (Figure 5).
Best Practice: Install/connect the MagWeb GT to the Internet while
the rest of the array is being installed. Doing so allows the MagWeb
GT to automatically update its internal software while the installation
is underway. The MagWeb GT communicates with the microinverters
once the installation is complete and the array is energized.

Figure 8, Connecting the MagWeb GT Wirelessly
2.4.3 Connecting using a PLC Bridge
Note: A PLC bridge uses the power line to communicate, and requires
both a “send” and “receive” unit (see Figure 9). The quality and
length of the CAT5 network cable will affect the quality of the MagWeb
GT’s communication. You can use a Switch to enhance quality of
communication, if necessary.
1. Ensure the CAT5 network cable is connected to the Network port
on the bottom of the MagWeb GT.
2. Connect the other end of the CAT5 network cable to the “send”
unit of the PLC bridge.
3. Route and connect another CAT5 network cable from the
“receive” unit of the PLC bridge to an open port on the broadband
router (refer to your bridge user’s manual for specific operating
instructions).
