5.1 Requirements for Mounting the Inverter

Requirements for the mounting location:

Danger to life due to fire or explosion

Despite careful construction, electrical devices can cause fires.

• Do not mount the inverter in areas containing highly flammable materials or gases.

• Do not mount the inverter in a potentially explosive atmosphere.

Risk of burns due to hot surfaces

The surface of the inverter can get very hot. Touching the surface can result in burns.

• Mount the inverter in such a way that it cannot be touched inadvertently.

• Do not touch hot surfaces.

• Wait ten minutes for the surface to cool sufficiently before performing any work on the inverter.

• Observe the warning messages on the inverter.

☐ To ensure optimum operation, the ambient temperature should be between -40°C and 65°C. ☐ The mounting location should not be exposed to direct solar irradiation. Direct solar irradiation

can cause the inverter to overheat. As a result, the inverter reduces its power output. ☐ Climatic conditions must be met (see Section14 "Technical Data", page66). ☐ The mounting location must be inaccessible to children. ☐ The mounting location must be suitable for the weight and dimensions of the inverter (see

Section14 "Technical Data", page66). ☐ The inverter must be mounted on the roof on the framework underneath the PV modules or on

a solid support surface (e.g. concrete, brickwork). In living areas, ensure that the support

surface is not drywall or similar. When in operation, the inverter makes noises which can be

perceived as a nuisance. ☐ When mounting on the framework, the mounting position should preferably be in the center of

the PV module. This will ensure a longer electrical endurance of the inverter.

Figure 9: Recommended clearances

SMA Solar Technology AG

Minimum Clearance between Inverter and PV Module Bottom Side:

Damage to the PV module due to insufficient clearance between the inverter and the PV module bottom side

For roof mounting, the clearance from the inverter to the bottom side of the PV module must be at least 30 mm. This will prevent the grounding bolt from damaging the PV module.

Figure 10: Minimum clearance of the inverter to the bottom side of the PV module

Permitted Mounting Position:

Electric shock due to ingress of moisture

• During mounting, make sure that the connection area of the inverter remains dry. As soon as the connector and protective cap are plugged in, the connection area will be protected from moisture ingress. Thus, the inverter complies with degree of protection IP65.

☐ In order to ensure optimum operation and long electrical endurance of the inverter, install

each inverter centered under the respective connection socket of the PV module.

☐ For installations that are integrated into the building, do not install the inverter directly on the

back side of the PV module. This will prevent the inverter power from being reduced due to excessive ambient temperature.

5.2 Mounting the Inverter

5.2.1 Mounting the Inverter on the Roof

Risk of falling when working on the roof

There is a risk of falling or slipping when working on the rooftop. Observe the applicable accident prevention regulations for work on rooftops.

• Before stepping on the rooftop, ensure the load bearing capacity of all parts subjected to load.

• In accordance with the accident prevention regulations, a safety harness must be worn or a safety scaffold must be used.

• Use a fall protection.

When mounting the inverter on the roof underneath the PV modules, proceed as follows. You can mount the inverter with the back panel or with the enclosure lid to the roof. SMA Solar

Technology AG recommends mounting the inverter with the enclosure lid to the roof. This will allow for better heat dissipation. Observe the minimum clearance of the inverter to the PV module (see Section5.1 "Requirements for Mounting the Inverter", page20).

Information on the figures in this section

The figures show the recommended mounting option for the inverter with the lid facing the roof. The procedure for mounting the inverter with the back panel facing the roof is identical and is not depicted in the figures in this section.

Position of the inverter

In order to ensure optimum operation and long electrical endurance of the inverter, install each inverter centered under the respective junction box of the PV module.

Additionally required mounting material (not included in the scope of delivery):

☐ The required fastening material must be selected according to the profile rail used. ☐ The mounting material must be made of stainless steel. ☐ Diameter of the screws: maximum 8mm

Damage to the PV module due to screws being too long

The length of the screws must be suitable for the clearance between the inverter and the PV module bottom side.

• Make sure that the PV module is not damaged by the screws being used.

There are several options for attaching the inverter to the framework on the roof. In the following example, mounting with T-head bolts is described.
