2 Safety
2.1 Intended Use
Multigate XT
The Multigate XT is an outdoor rated enclosure containing between 1 and 4 Sunny
Multigates, associated terminal blocks for inputs from each string of Sunny Boy micro
inverters, associated terminal blocks for outputs of each Sunny Multigate to the AC
Grid connection point, and associated hardware for Speedwire/Webconnect (related to
Ethernet) connection for monitoring system performance over the internet.
Figure 1: Design of a PV plant with Sunny Boy 240-US and Multigate XT
The Multigate XT contains between 1 to 4 Sunny Multigates, each of which are a
communication unit that forms the connection point of the PV plant with a maximum
of twelve micro inverters to the utility grid. The Multigate XT is connected between the
Sunny Boy 240-US micro inverter and the utility grid to feed the alternating current
converted by the inverters collectively into the utility grid. The Multigate XT is designed
for split-phase operation only. The Multigate XT must be operated in conjunction with
SMA Sunny Boy 240-US.
Multigate XT

Installation Manual - TEAL PN 1060147 rev 2.5 11
TEAL Electronics SMA America, LLC
The Multigate XT is designed in a dust-tight and water-tight industrial enclosure
complying with the fire protection class 5VA and pollution degree 3. The enclosure must
comply at a minimum with UL50 Type 3 when conduits are installed.
For safety reasons, it is forbidden to modify the product or install components that are
not explicitly recommended for this product.
Only use the Multigate XT in accordance with the information provided in the enclosed
documentation. Any other use can result in personal injury or property damage.
• Each Multigate XT contains from 1 to 4 Sunny Multigates. The model number
designation contains the number of Sunny Multigates in each Multigate XT. Model
XT1 contains 1 Sunny Mulitgate. Model XT2 contains 2 Sunny Multigates. Model
XT3 contains 3 Sunny Multigates. Model XT4 contains 4 Sunny Multigates.
• A maximum of twelve micro inverters can be connected to each Sunny Multigate.
• No loads may be connected between the Sunny Multigate and the circuit breaker.
• The grounding conductor of the AC cable from the inverter must be connected to the
corresponding Sunny Multigate grounding terminal in the Multigate XT.
• The output grounding conductor of the Multigate XT must be connected to the
equipotential bonding of the AC distribution board.
• The Sunny Multigate must not be opened.
The enclosed documentation is an integral part of this product.
• Read and observe the documentation.
• Keep the documentation in a convenient place for future reference.
2.2 Skills of Qualified Persons
The tasks described in this document must be performed by qualified persons only.
Qualified persons must have the following skills:
• Knowledge of how an inverter works and is operated

2.3 Safety Precautions
Str
Danger to life from electric shock due to high voltages
In the live components of the Multigate XT, high voltages are present that can cause
fatal electric shocks if touched.
• Do not open the Sunny Multigate.
• Do not touch any live components of the Multigate XT.
• Prior to performing any work on the Multigate XT, disconnect it from any voltage
sources.
• Observe the safety messages on the inverter and the Sunny Multigate.
Danger to life from electric shock due to ground fault
If a ground fault has occurred, parts of the plant that are supposedly grounded may
in fact be live. Death or serious injuries can occur from contact with live components.
• Prior to touching any components, always disconnect the Multigate XT from any
voltage sources.
Danger to life from electric shock due to damaged devices
Operating a damaged Multigate XT can lead to hazardous situations that result in
death or serious injuries due to electric shock.
• Only operate the Multigate XT providing that it is in safe and full working order.
• Regularly check for visible damage.
Damage to the Multigate XT from moisture and dust intrusion
Dust or moisture intrusion can damage the Multigate XT and impair its functionality.
The Multigate XT must always be installed in compliance with UL50E. This ensures
that the Sunny Multigate is protected against dust and moisture and is suitable for
indoor and outdoor operation.
•The Multigate XT must be installed in compliance with a Type 4 industrial
enclosure with pollution degree 3.
•Use only conduit fittings, hubs, or connectors that also meet the requirements of
a Type 4 industrial enclosure with pollution degree 3.
