SMA Solar Technology AG Mounting the Device
Installation Guide SB20_25_30HF-IEN102911 17
• Vertical installation or tilted backward by max. 30°.
• The connection area must point downward.
• Never mount the device with a forward tilt.
• Never install the device with a sideways tilt.
• Do not mount horizontally.
• Mount at eye level to allow operating status to be read at all times.
• The ambient temperature should be below +40 °C to ensure optimal operation.
• Do not expose the inverter to direct sunlight to avoid a power reduction due to excessive
heating.
• In living areas, do not mount the unit on plasterboard walls or similar in order to avoid audible
vibrations. The inverter can make noises when in use, which may be perceived as a nuisance in
a living area.
• Observe the minimum clearances to walls, other
inverters or objects as shown in the diagram in
order to ensure sufficient heat dissipation and
sufficient space for the removal of the Electronic
Solar Switch.
Multiple inverters installed in areas with high ambient temperatures
If necessary, increase the clearances between the individual inverters. In addition, make
sure there is enough ventilation to ensure sufficient cooling of the inverters.
