SUNNY BOY 3000-US

SUNNY BOY 3000-US / 3800-US / 4000-US

UL listed, reliable system managers

Specially designed for countries that require UL listing, these Sunny Boy inverters guarantee a safe installation process thanks to the automatic grid voltage detection¹. The integrated DC circuit breaker simplifies the installation process and saves installation costs. Since the devices are suitable for PV array grounding, they can be combined with all module types. In addition, OptiCool guarantees the highest yields possible and a long electrical endurance, even under extreme conditions. The Sunny Boy 3800-US is designed for projects with a current limit of 16 A.

Bluetooth interface Piggy-Back

The retrofit Bluetooth communication interface Piggy-Back enables wireless communication between the SMA inverter and SMA communication devices.

Also available with offset antenna for an optimized Bluetooth reception.

RS485 Piggy-Back

The RS485 wiring for plant monitoring and communication allows functional lengths of up to 15235 meters. The Sunny WebBox collects all the data and informs you about the status of the PV plant. With Piggy-Back the data transmission is reliable even in interference-prone areas. Subsequent expansions are possible without problem thanks to the modular design principle.
