Compact Medium Voltage Block optimized for integration with the Sunny Central

Medium Voltage Block 1850-US-2.0 / 2200-US-2.0 / 2500-US-2.0 / 2750-US-2.0

Compact Medium Voltage Block optimized for integration with the Sunny Central

The Medium Voltage Block is the perfect partner for the Sunny Central inverter and has been specifically designed to offer the lowest installed cost. Convenient kitted components offer vastly simplified field integration while eliminating the need for skid solutions that can increase logistical complexity. Transformer monitoring facilitated through the inverter MODBUS reports analog values for temperature and pressure, which enables trend-based predictive maintenance. The new Medium Voltage Block further advances the level of integration in SMA’s Utility Power System, creating the lowest risk, highest return utility PV solution available.

Your benefits

Cost Optimized

  • High level of system integration eliminates the need to purchase additional equipment and the labor costs associated with field wiring

  • Optimized footprint is 22% smaller than previous version, saving on transportation, logistical and material costs
