Description

The highly anticipated SMA Sunny Boy Smart Energy 4.8kW hybrid inverter. It’s the hybrid inverter at the heart of the SMA Energy System, with three backup options. This groundbreaking inverter combines the functions of a PV and battery inverter into a single unit, keeping electrical upgrades to a minimum. SBSE4.8-US-50

The SMA Sunny Boy Smart Energy 4.8kW features modular add-on options including the new SMA Energy Meter and SMA Backup Secure that enhance the systems’ performance and offer peace of mind.

BackUp Options

SMA BACKUPSECURE
Secured power supply Access up to 1,900 W of power with a secure outlet connected directly to your inverter.
SMA BACKUPSELECT
Selected power supply Get up to 3,800 W of power, with or without a battery, automatically sent to select loads in your home when the grid goes down.
SMA BACKUPHOME
Reliable power supply When paired with a battery, store and access the full power of your PV system to power your home in the event of grid failure.

Sunny Boy Smart Energy inverters are packed with new technology, including an integrated system manager, SMA 360° and Energy apps, SunSpec RSD transmitter, SMA ShadeFix optimization (with 3 MPPTs), SMART Connected and more. The Sunny Boy Smart Energy shines with its high-speed battery charging capability. Conventional charging performance is challenged during transitional months by few hours of sunshine and plenty of cloud cover, but Sunny Boy Smart Energy’s fast charging allows more solar power to be harvested and stored in those few hours, ready to power loads and reduce energy costs.

Trust in SMA America, your leader in residential energy – building reliable, high performance and innovative solutions, with support you can depend on. For over 40 years, SMA has made using solar energy easier and more efficient. The SMA Energy System Home continues this tradition.
