4.4 Communication
Communication between inverter and Sunny MultigateThe inverters are connected to the Multigate XT, and consequently the Sunny Multigate, via the AC cable. The communication and data transmission between the Sunny Multigate and the inverters takes place via a Powerline interface.
Communication between Sunny Multigate and other communication products Communication between the Sunny Multigate and other SMA communication products (e.g. Sunny Portal, Sunny Explorer) takes place via Speedwire. Speedwire is an Ethernet-based type of communication. You can connect the Sunny Multigate to your network via Speedwire. The Webconnect function enables data exchange between Sunny Multigate and Sunny Portal. Sunny Portal is an Internet portal for the monitoring of plants as well as for the visualization and presentation of plant data. In order to establish a connection to Sunny Portal, the Sunny Multigate must be connected to a router with Internet connection and be integrated into your network. To enable data exchange between Sunny Multigate and Sunny Portal, you must register the PV plant in Sunny Portal (see user manual of Webconnect plants in Sunny Portal at www.SMA-Solar.com). For this purpose, you will need the access data, identification key (PIC) and registration ID (RID) which are located on the type label of the Sunny Multigate and the inside of the door of the Multigate XT. Once you have registered the Sunny Multigate, you will be able to monitor your PV plant in Sunny Portal.

5 Mounting
5.1 Selecting the Multigate XT Mounting LocationRequirements for the mounting location:
The mounting location must be inaccessible to children. The Multigate XT mounting location must not be exposed to direct solar irradiation.
Direct solar irradiation can cause the Multigate XT to overheat, and as a result the inverter system will reduce its power to 0W.
The Multigate XT must be properly mounted on the wall, preferrably mounted to the framework underneath the wall surface. In living areas, make sure that the building ground is not made of plasterboard or similar. When in use, the Sunny Multigate may make noises which can be perceived as a nuisance in a living area.
The mounting location must be suitable for the weight and dimensions of the Multigate XT. Model XT1 weighs a maximum of 12 lbs. Models XT2 weigh a maximum of 22 lbs. Models XT3 and XT4 weigh a maximum of 35 lbs.
The ambient temperature must be between –40°F and +113°F (–40°C and +45°C). This ensures optimal operation of the Multigate XT.
After installation, any unused conduit holes must use a plug that complies with at least NEMA 4 rating.
Use supplied non-metallic mounting feet provided to mount the Multigate XT to the wall.
Use a mounting hardware type suitable for the material the Multigate XT is being mounted to, and install the unit in compliance with all applicable building codes.
Use appropriate torque value to secure mounting hardware. Over-torquing of mounting hardware may result in cracking or breakage of the mounting feet.
Use appropriately sized hardware to mount the enclosures, recommended 1/4” hardware.
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires.
• Do not mount the Multigate XT on flammable construction materials.
• Do not mount the Multigate XT in areas where highly flammable materials are stored.
• Do not mount the Multigate XT in a potentially explosive atmosphere.
• Risk of Electric Shock. Do not Remove Cover. No User Serviceable Parts Inside. Refer
Servicing To Qualified Service Personnel.
• Hazardous Voltage remains for 5 minutes after disconnecting main power supply.
