Industrial repowering of a 500 kWp system

The Madama Oliva estate (producers of black olives) had already taken the step to invest in a 500 kWp photovoltaic system 10 years ago. However, two of the existing central inverters were no longer giving the yield they wanted, so the owners decided it was time to replace them. Fronius Service Partner PDF Green Energy S.r.l. recommended repowering the system and installing new inverters. The central inverters were replaced by multistring devices withan integrated monitoring system. A major advantage of the multistring inverters is that they minimise losses on both the AC and DC side, maintaining a stable and reliable energy supply.

The Fronius Symo was chosen for the repowering: with 2 MPP trackers it can be flexibly integrated into an existing system. 

Fronius Service Partner PDF Green Energy recommended choosing a product from Fronius. Superbly functioning devices, an integrated monitoring system, user-friendly data visualisation and professional service support from qualified installers meant the choice was an easy one for the plant operator.
