SMA Solar Technology AG, the world leader in solar inverter technology and manufacturing, knows open-air equipment in particular, like SMA’s Sunny Central CP series, has to withstand these conditions, reliably performing for the operational life of the PV plant, which often exceeds 20 years. All components of an inverter, and especially its interior, need to be securely sealed to protect against the damaging effects brought on from desert storms and enormous temperature swings.
The stress imposed by sandstorms can be especially severe, as the very fine dust can penetrate even the smallest openings, potentially causing problems within the interior of the inverter, the key component in any PV system. This fine sand and dust settling on an inverter’s sensitive electronics represents an enormous potential risk to the operation and longevity of the entire PV plant.
The Sunny Central CP integrated OptiCool™ system eliminates this problem, as proven by SMA’s sand and dust tests. SMA subjected the Sunny Central CP to intensive testing in order to demonstrate that Sunny Central CP inverters are engineered for outdoor use in conditions where dust and sand is prevalent in the ambient air.
