XHub: The Unified Energy Brain Powering the Future of Smart Home Energy

The future of home energy is no longer just about generating power — it’s about using it smarter. As households adopt solar, storage, EVs, heat pumps and smart appliances, the real challenge becomes clear: How do you get all these devices to work together efficiently, autonomously, and economically?

Introducing SolaX XHub — a unified energy controller designed to transform traditional solar systems into intelligent, future-ready home energy ecosystems.

One-Stop Management for the Entire Home Energy System

With external CT options and flexible integration capabilities, SolaX XHub enables full-household load management. By coordinating PV generation, battery charge and discharge, EV charging behavior, heat pump operation and household loads, XHub ensures the home always uses energy in the smartest possible way.

Homeowners gain a comprehensive real-time view of their entire energy flow — what is generating, what is consuming, what is being saved and what is being optimized. The result is simple, unified and intelligent control across the entire PV–ESS–EV–HP ecosystem.

Smarter Energy Decisions Powered by AI

At the core of XHub is XSchedule, an AI-driven scheduling engine built specifically for distributed energy resources (DERs). XSchedule continuously analyzes real-time operating conditions and external market signals, making automated decisions that maximize economic value.

Whether it’s charging your battery when prices drop, shifting loads to maximize green power, or selling energy at the right moment, XHub works 24/7 to improve your returns.

Edge Intelligence: Real-Time Optimization

On-site, XHub collects granular data from PV generation, battery SOC, load curves, ambient temperature and device priorities. The edge controller can then:

• Execute millisecond-level responses

• Adjust discharge and charging behavior

• Enforce priority-based load management

• Maintain system-level three-phase balance

• Detect and correct CT polarity or phase-sequence issues

This ensures high system stability even in fluctuating grid or load environments.

Cloud Intelligence: Forecast-Driven Optimization

The cloud engine adds high-level predictive capabilities, including:

• 15-minute PV generation forecasts

• 15-minute load consumption forecasts

• Dynamic electricity price indexing

• Weather-driven irradiance estimation

• Continuous machine-learning model training

With forecast accuracy exceeding 96%, XHub provides optimized strategies far more efficient than traditional rule-based energy controllers. In real deployments, homeowners can boost revenue by 50% or more, depending on their tariff structure and system configuration.

Designed for Real Homes and Real People

XHub was built with installers and homeowners in mind.

Fast for Installers

• DIN-rail mounting for clean wiring

• One-click Bluetooth configuration

• Auto-device detection

• Direct or CT-based grid connection

• Compatible with most distribution boxes

This results in faster commissioning, fewer configuration errors and smoother installation workflows.

Effortless for Homeowners

• One-screen system overview

• Drag-and-drop load priority

• Real-time statistics

• Monthly energy insights

• Seamless pairing with SolaXCloud App & Web

Even first-time solar users gain an accessible and powerful energy management experience.

PV–ESS–EV–HP Whole-Home Load Solutions Powered by XHub

To accommodate different households and electrical requirements, SolaX provides two flexible configurations:

Solution for Loads Below 80 A — Direct Meter Replacement

For typical homes with loads under 80 A, XHub enables a meter-replacement-only installation:

• XHub directly replaces the home’s existing meter

• No additional rewiring for AC OUT

• Full PV-ESS-EV-HP-LOAD orchestration

This enables a clean and rapid deployment while providing complete visibility and control of all major loads.

Solution for Loads Above 80 A — External CT Architecture

For larger households or applications exceeding 80 A, XHub supports an External CT (Current Transformer) solution.

In this mode:

• The original meter’s AC IN line remains intact (not linked to AC OUT)

• XHub uses an external CT to measure total household consumption

• Installers can select appropriate 40 mA output CTs (100A/200A/400A/600A) based on site conditions

This ensures accurate power sensing and reliable whole-home load control even for large or three-phase residential systems.

Third-Party Ecosystem Integration

More than a controller, XHub is an open platform designed to connect with a growing smart-home ecosystem.

Smart Home Integration with Shelly

XHub supports direct integration with Shelly smart plugs and smart home devices, enabling:

• Remote ON/OFF control

• Load-level automation

• "Green-energy-only" power modes

Heat Pump Integration

• SolaX Thermal R290 Series heat pumps connect directly via Modbus TCP, enabling precise, data-rich control.

• Other heat pump brands connect through SG Ready, enabling demand shifting and energy-based operation control.

Third-Party Inverter Integration

SolaX XHub supports integration with third-party inverters in retrofit scenarios, enabling unified control even in mixed-brand PV systems.

EEBUS Alliance Ecosystem

Through EEBUS, XHub integrates with next-generation smart home appliances, positioning it as a central energy controller within the smart home ecosystem.

Ready for Tomorrow's Energy Market

As global grids adopt dynamic tariffs, demand response programs and VPP aggregation, regulatory compliance becomes essential. XHub incorporates built-in support for major global standards, including:

• Ripple Control

• DRM (Demand Response Mode)

• OpenADR

• IEEE 2030.5

• SunSpec

• §14a EnWG & §9 EEG (Germany)

This ensures interoperable communication with DSOs, VPP aggregators and demand-response platforms, enabling homes to participate in modern grid programs without additional hardware.

Protected by Industry-Leading Security Standards

Smart homes rely on smart data, and SolaX ensures that data remains secure.

Global Certifications

• SOC 2 Type II – Industry’s highest-level validation of cloud security

• ISO 27001 – International standard for information security

• EN 18031 – GDPR-aligned protection of sensitive customer data

• PSTI Compliance – Built-in cybersecurity protections and lifecycle updates

With these certifications, homeowners can trust that their data and devices remain protected throughout their entire lifecycle.

Conclusion: XHub Sets a New Benchmark for Intelligent Home Energy Control

XHub represents a step forward in the technical evolution of residential energy controllers. By integrating multi-device interoperability, AI-based scheduling, system-level diagnostics and grid-ready compliance, it provides a robust control platform capable of meeting the operational demands of modern distributed energy systems.
