SMA Sunny Boy Smart Energy 4.8-US 4.8kW Single-Phase Hybrid Inverter

About This Product

The SMA Sunny Boy Smart Energy 4.8-US 4.8kW Single-Phase Hybrid Inverter is a residential hybrid inverter designed to combine solar PV conversion and battery integration in a single unit. Model SBSE4.8-US-50 provides 4.8kW of AC output and supports 208V and 240V grid connections. It can be installed initially as a PV inverter and configured with compatible high-voltage battery storage when required. The inverter also incorporates SMA’s ShadeFix technology and a SunSpec-certified rapid-shutdown transmitter for integration into NEC-compliant residential PV designs.

Who This Product Suits

The SMA Sunny Boy Smart Energy 4.8-US is suited to residential solar installations where the system designer wants a single-phase string inverter with a pathway to battery storage. It is particularly useful for homes that may start with solar only and add compatible DC-coupled storage later. Multiple MPPT channels provide flexibility when designing arrays across different roof orientations or electrical operating conditions. Installation, string sizing, rapid shutdown equipment and overcurrent protection should be designed by a qualified solar professional in accordance with the NEC, local utility requirements and SMA installation instructions.

Specifications Explained

• 4.8kW power class: Provides up to 4,800 watts of AC output for appropriately sized residential PV systems.
• Single-phase hybrid design: Combines the functions of a PV inverter and compatible battery inverter in one platform.
• 208V / 240V operation: Supports common US residential and applicable 208V electrical services when installed according to SMA requirements.
• PV and battery capability: Supports solar-only operation as well as DC-coupled battery storage using SMA-approved compatible batteries.
• Multiple MPPT channels: Provides independent solar tracking channels that give installers greater flexibility when laying out arrays with differing orientations or operating conditions.
• 200% DC/AC design capability: SMA permits substantial PV array oversizing when the system is designed within the manufacturer’s electrical limits.
• Rapid shutdown support: Includes a SunSpec-certified rapid-shutdown transmitter for use with compatible rapid-shutdown devices in NEC-compliant installations.
• SMA ShadeFix: Integrated software-based yield optimization helps manage PV strings affected by changing shade conditions.
• Commissioning and monitoring: Supports installer commissioning through the SMA 360° app and integration with SMA’s home energy monitoring ecosystem.
• Warranty: Supplied with a 10-year manufacturer warranty, subject to SMA’s warranty terms and registration requirements.

Summary

The SMA Sunny Boy Smart Energy 4.8-US is a 4.8kW single-phase hybrid inverter for US residential solar and energy-storage systems. SMA combines PV conversion, compatible DC-coupled battery support, multiple MPPT channels, ShadeFix, rapid-shutdown integration and system monitoring within one inverter platform. It is a practical choice for installers designing a residential PV system that can operate as solar-only today while retaining the option to integrate compatible battery storage and SMA energy-management equipment.
