Figure 3-4 Inverter Wall Mounting Baffle Details 

NOTICE!

 

Ensure that the air space around the inverter is well ventilated. The spacing between two adjacently wall 

mounted inverters may be reduced to 

≥

13.8in (350mm) provided a baffle is installed. Installing an aluminum 

or galvanized steel baffle (Not supplied by Yaskawa Solectria Solar) with the dimensions detailed above is 

intended to divert or deflect warm exhaust air from entering the adjacent inverter. Elevated ambient air 

temperature 

≥

 45

°

C will cause the inverter to enter a thermal derating mode and reduce its active power 

output.
