For commercial building we suggest you the threephase inverter by SMA suitable for any solar panel with the best yield. Thanks to an advance technology the Sunny Tripower inverters offer the easiest way to configurate pv systems. All devices communicates through Bluetooth allowing an easy monitoring of the solar system.
This solar inverters increase the efficiency (98%) and decrease the cost of managing the system. This involves an high performance and an further incentive to invest in solar energy.
