SMA Sunny Home Manager 2.0 (HM-20) – EMS with Integrated Energy Meter

Core Function: Intelligent Energy Flow Optimisation

Maximising Self-Consumption

The Sunny Home Manager 2.0 continuously evaluates PV production, household consumption, and battery status. Based on this data, it optimises how and when energy is used, stored, or fed into the grid.

This results in:

• Higher on-site use of solar energy

• Reduced grid import

• Improved return on investment for PV and storage systems

Predictive Energy Management

By combining historical consumption data with weather and PV production forecasts, the Sunny Home Manager 2.0 enables predictive control strategies. Energy flows are planned in advance rather than reacting only to real-time conditions.

System Integration and Compatibility

Native Integration with SMA Systems

The Sunny Home Manager 2.0 is designed to work seamlessly with the SMA ecosystem, including:

• SMA PV inverters

• SMA Home Storage battery systems

• SMA energy meters

• Supported controllable loads and devices

This tight integration ensures stable communication, coordinated control, and reliable long-term operation.

Central Control Unit

Rather than acting as a meter or inverter, the HM-20 functions as the central decision-making unit of the system. It receives measurement data, processes it, and issues control commands to connected SMA components.

Battery and Load Management

Optimised Battery Usage

When combined with SMA battery storage, the Sunny Home Manager 2.0 manages charging and discharging cycles intelligently. It prioritises self-consumption, avoids unnecessary grid export, and adapts battery behaviour to expected production and demand.

Load Prioritisation and Control

The system supports intelligent control of electrical loads, allowing energy-intensive devices to operate when solar power is available. This helps reduce peak grid demand and improves overall system efficiency.

Monitoring and Transparency

Comprehensive System Visibility

The Sunny Home Manager 2.0 integrates with SMA monitoring platforms, providing real-time and historical insights into:

• PV production

• Energy consumption

• Battery state of charge

• Grid import and export

System data is accessible via web and mobile applications, enabling installers and system owners to track performance and identify optimisation potential.

Installation and Commissioning

Installer-Friendly Design

The HM-20 is designed for professional installation as part of SMA PV systems. Once installed and configured according to SMA guidelines, it automatically integrates into the system architecture.

Correct commissioning ensures:

• Accurate energy measurement

• Reliable communication with system components

• Stable long-term operation

Future-Ready Energy Management

The Sunny Home Manager 2.0 is designed to support evolving energy markets and system requirements, including:

• Increasing battery adoption

• Dynamic electricity tariffs

• Sector coupling (e.g. heating, mobility)

• Higher levels of decentralised energy production

This makes it a long-term solution for energy systems that need to adapt over time.

Typical Applications of the SMA Home Manager 2.0

• Residential PV systems with battery storage

• Hybrid PV installations

• Self-consumption optimisation projects

• Energy-aware households and light commercial sites

• SMA-based energy management solutions

The SMA Sunny Home Manager 2.0 (HM-20) is the intelligent control layer that unlocks the full potential of SMA PV and storage systems. By combining predictive energy management, battery optimisation, and transparent monitoring, it enables higher self-consumption and more efficient energy use.
