5 Mounting
Structural Stability:
☐ When mounting with feet or profile rails, the width of one foot or the profile rail must be at
least 175 mm (7 in) to ensure structural stability.
☐ The inverter must be attached under the following conditions:
– Inclination of the support surface: > 3°
– Wind speed (without wind gusts): > 25 m/s (82 ft/s)
– Height of the feet or the profile rail: > 100 mm (4 in)
☐ When mounting with profile rails, an attachment or fixation by loading is required. When
mounting with profile rails, SMA Solar Technology AG recommends to bolt the profile rails
e.g. to the profile of the module frame or to attach a sheet metal (which can be weighted with
stones or with sandbags) at the profile rails. This will ensure that the inverter is fixed.

Recommended clearances:
To guarantee optimal operation and adequate heat dissipation for the inverter, the following
requirements for clearances should be observed. This will prevent the inverter power output from
being reduced due to excessive temperatures. However, smaller clearances are permitted without
causing any risk.
Prescribed clearances in accordance with the National Electrical Code
Canadian Electrical Code
Under certain conditions, the National Electrical Code
CSA C22.1 specify greater clearances.
• Ensure that the prescribed clearances in accordance with the National Electrical Code
or Canadian Electrical Code
☐ Maintain the recommended clearances to roof edges, skylights, walls as well as to other
inverters or objects. This ensures that the load-break switches on the inverter can be operated
easily and the LED signals can be read without difficulty.
☐ For possible service deployments, SMA Solar Technology AG recommends ensuring sufficient
clearance from walls, other inverters or objects on all four sides of the inverter enclosure. Non-
fulfillment of these criteria may restrict servicing.
