SUNNY BOY 2000HFUS / 2500HFUS / 3000HFUS

Designed for easy installation, simple communication and maximum performance

The new Sunny Boy high frequency inverters represent the next step in innovative SMA technology. Featuring world-class efficiency, a slim-line enclosure and reduced weight, the Sunny Boy HF series of inverters can be mounted in between wall studs, making it perfect for new construction, in addition to space-constrained retrofits. Installation is made simple by automatic grid detection**, field configuration for positive ground and a wide input voltage range of 175 to 600 volts, which provides exceptional system design flexibility. The modern graphic display and wireless Bluetooth® communication system also makes the new Sunny Boy easy to use.
