SMA Sunny Boy Smart Energy 7.7-US 7.7kW Single-Phase Hybrid Inverter

About This Product

The SMA Sunny Boy Smart Energy 7.7-US 7.7kW Single-Phase Hybrid Inverter is a residential hybrid inverter designed to combine PV conversion and DC-coupled battery integration in a single unit. Model SBSE7.7-US-50 provides 7.65 kW of AC output and supports both 208 V and 240 V applications. It is part of SMA’s Sunny Boy Smart Energy platform and can be installed initially as a PV inverter or incorporated into a compatible battery storage system.

Who This Product Suits

This SMA inverter suits residential grid-connected solar installations where the system designer wants a single-phase inverter with a pathway to battery storage. It is particularly useful for new solar-plus-storage projects, PV systems where storage may be added later, and installations requiring flexible array design. The inverter is intended for professional installation and should be selected and commissioned in accordance with applicable NEC requirements, utility interconnection rules, and SMA system design requirements.

Specifications Explained

• 7.65 kW AC output: The SBSE7.7-US power class is designed for residential PV systems requiring up to 7,650 watts of inverter output.
• 208 V / 240 V operation: Supports common US residential and applicable 208 V electrical services when configured according to SMA requirements.
• Hybrid architecture: Combines PV inverter and compatible DC-coupled battery inverter functions in one unit, allowing solar generation and energy storage to be managed through the same inverter platform.
• Three MPPT channels: Provides independent PV tracking channels for greater flexibility when designing arrays with different orientations or operating conditions.
• Up to 200% DC/AC design capability: SMA permits substantial PV array oversizing when the system is engineered within the manufacturer’s electrical limits.
• Integrated SMA ShadeFix: SMA’s inverter-based yield optimization technology helps manage PV production where array operating conditions vary.
• Rapid shutdown support: Includes a SunSpec-certified rapid shutdown transmitter for integration with compatible module-level rapid shutdown equipment in NEC-compliant system designs.
• Monitoring and commissioning: Supports SMA’s digital commissioning and monitoring ecosystem, including the SMA 360° installer app and Sunny Portal powered by ennexOS.
• 10-year manufacturer warranty: Supplied with SMA’s standard 10-year manufacturer warranty, with extended warranty options available from SMA.

Summary

The SMA Sunny Boy Smart Energy 7.7-US is a 7.65 kW single-phase hybrid inverter for US residential solar and energy-storage systems. Its combination of PV conversion, DC-coupled battery capability, three MPPT channels, rapid shutdown support, SMA ShadeFix, and SMA monitoring makes it a practical choice for installers building a solar system that can operate as PV-only or form the core of a compatible SMA home energy storage solution.
