9.2 Shade Cover (SSC-60ST)
9.2.1 Protection from Harsh Conditions
Shade covers provide added protection for inverters against harsh
environmental conditions like direct sunlight, snow, sleet, ice, hail, and
reduce soiling from dust and birds. When installing the inverter at
tilts of 75° or less from horizontal the shade cover is required.
Protect your inverter for many years.
9.2.2 Increased Energy Production
Depending on the application and environment, shade covers will help
to increase energy production by reducing potential power derating
due to excessive ambient temperatures. Inverters derate in extreme
temperatures to protect themselves from over temperature conditions.
Field testing at PVEL showed up to 15% reduction in operating
temperatures of inverters with shade covers installed in direct sunlight.

application notes.
