TCL SunPower Global has announced the launch of its new Energy Storage System, a major step forward in creating a fully connected home energy ecosystem. Designed to work seamlessly with SunPower solar panels and the SunPower app, this new solution empowers homeowners to maximize their solar investment and take control of their energy future.
“This new system delivers a complete, compatible energy ecosystem from one trusted brand,” said Steven Zhang, GM of TCL SunPower. “We are committed to being the reliable single supplier for our installation partners, expanding our portfolio with solutions that make their work easier and giving them one point of contact for everything—sales, warranty, and support. This approach simplifies processes, reduces complexity, and makes their work easier. Combined with the best price-to-value ratio, it’s a solution designed to help installers run their business more smoothly and profitably.”
Part of a Complete SunPower Home Energy Ecosystem
The new SunPower Energy Storage System stores excess solar energy for use when it’s needed most, during peak pricing periods, at night, or even during unexpected outages. Paired with the SunPower app, homeowners can effortlessly monitor and optimize their energy usage and savings, while the system unites solar generation, storage, and seamless management in a single platform. This integration delivers simplicity and control through one trusted brand, one account, and one app, making clean energy at home easier than ever.

Engineered for Safety and Reliability
The SunPower home energy system meets the highest safety standards, accredited by TÜV Rheinland. It features:
- Multi-level temperature control: 8 thermal sensors in each battery pack trigger a range of automated tools from energy intensity controls to load shedding and pressure release.
- Adaptive power algorithms: Designed to maximize battery lifespan, SOC optimization also acts as a powerful safety brake.
- Glass fibre Aerogel cell insulation: The lightest solid material known, with the lowest possible density, wraps each cell in a high-temperature-resistant fire blanket.
- Internal fire extinguisher: Aerosol release (15 s) of phase-change particles and gas absorbs extreme heat and arrests the chemical reaction sustaining combustion.
Orders for the new Energy Storage System open on December 9 in Italy and France, where the product officially launched today. A broader rollout across additional EU countries is planned for early 2026, marking a significant step toward integrated home energy solutions.
