SHERIDAN, WYOMING - December 10, 2025 - TCL SunPower Global is expanding its European residential solar strategy with a new fully integrated home energy storage system designed to work natively with SunPower solar panels and the SunPower app, giving installers and homeowners a single-vendor ecosystem for generation, storage and digital energy management.
From Standalone Batteries to a Connected Home Energy Ecosystem
The new SunPower home energy storage system is positioned as the core of a connected domestic energy ecosystem rather than a standalone battery. By combining PV generation, storage and load control through one brand, one account and one app, TCL SunPower aims to simplify deployment and post-sale support for its installer partners while helping homeowners maximize self-consumption and energy independence.
The system is engineered to store surplus solar energy for use during evening peaks, overnight or during unexpected outages, turning intermittent PV production into a more predictable, controllable resource. In markets like France and Italy, where tariff structures and incentive schemes increasingly reward smart self-consumption, this integration is becoming a key commercial differentiator for installers.
Channel-Centric Value Proposition for European Installers
TCL SunPower is explicitly framing the launch around installer economics and operational simplicity. "Este sistema ofrece un ecosistema completo y fiable bajo una marca de confianza", afirmó Steven Zhang, director general de TCL SunPower. "Nuestro compromiso es convertirnos en el proveedor único y seguro para nuestros socios instaladores, ampliando nuestra cartera con soluciones que simplifican su trabajo y ofreciendo un único punto de contacto para ventas, garantía y soporte. Este enfoque reduce la complejidad, agiliza procesos y mejora la rentabilidad. Combinado con una excelente relación calidad-precio, es la solución ideal para ayudar a los instaladores a gestionar su negocio de forma más eficiente".
For B2B partners, that "single point of contact" means harmonized logistics, warranties and technical support across modules, storage and digital services. This reduces truck rolls, cross-vendor troubleshooting and fragmented service agreements-cost drivers that erode margins in residential solar projects.
Technical Architecture: Scalable Capacity and Fast Backup
The new storage platform is designed for European residential grids with both single-phase and three-phase models and modular battery blocks that allow system sizing from 5 kWh up to 30 kWh. This enables installers to tailor storage capacity to different household profiles, from small urban apartments to larger single-family homes with EV charging and heat pumps.
Key specifications include:
- Models: Single-phase and three-phase
- Battery capacities: 5 / 10 / 15 / 20 / 25 / 30 kWh
- Chemistry: Lithium iron phosphate (LiFePO₄) for safety and long cycle life
- Backup capability: Integrated automatic transfer with sub-10 millisecond switching
- Connectivity: Full integration with the SunPower app for real-time monitoring and control
- Certification: TüV Rheinland safety accreditation
- Warranty: 10 years
The combination of LiFePO₄ chemistry, fast switchover and app-based monitoring is intended to support both self-consumption optimization and critical-load backup, aligning with the growing European demand for resilience against grid instability and extreme weather events.
Safety-First Design for Densely Populated European Housing
Safety and regulatory compliance are major concerns in European residential deployments, especially in dense urban environments and multi-unit buildings. The SunPower system incorporates multiple layers of protection designed to meet stringent local standards.
These include:
- Multilevel thermal management with eight sensors per battery pack triggering graduated protective actions from current derating to pressure release
- Adaptive power algorithms that optimize state of charge (SOC) to extend battery life and act as a safety brake under abnormal conditions
- Fiberglass aerogel cell insulation, wrapping each cell in a high-temperature, flame-resistant blanket to minimize thermal propagation risks
- Internal fire suppression via a 15-second aerosol release using phase-change particles and gas to absorb extreme heat and interrupt combustion chemistry
Taken together, these features are aimed at de-risking storage deployments for installers while providing homeowners and regulators with a high degree of confidence in system safety.
European Rollout: France and Italy First, Wider EU in 2026
Orders for the new storage system opened on 9 December in Italy and France, where TCL SunPower formally launched the product. These two markets provide a strong initial beachhead thanks to mature rooftop solar segments, supportive policy frameworks and growing consumer interest in energy independence.
The company plans to roll out the solution to additional EU countries from early 2026, using its dual-brand strategy-TCL Solar for high-efficiency panels and SunPower for integrated energy solutions-to cover residential, commercial and utility-scale segments. For distribution partners, the roadmap offers a clear path to expanding from module sales into full-stack energy solutions with recurring digital and service revenues.
As European households increasingly look for ways to buffer rising energy prices and decarbonize their homes, integrated solar-plus-storage ecosystems like SunPower's are set to become a central battleground for manufacturers, installers and utilities alike.
