TCL SunPower Global has unveiled its new Energy Storage System, a significant milestone in building a fully connected home energy ecosystem. Engineered for seamless integration with SunPower solar panels and the SunPower app, this innovative solution enables homeowners to maximize the value of their solar investment while gaining greater control over how they generate, store, and use energy.
“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 captures and stores excess solar power for when it’s needed most during peak rate periods, at night, or in the event of an outage. Integrated with the SunPower app, it allows homeowners to easily track, manage, and optimize their energy use and savings. By combining solar generation, battery storage, and smart control within one connected platform, SunPower delivers simplicity, reliability, and total home energy management through a single brand, account, and app.

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 hi-temperature resistant fire blanket.
– Internal fire extinguisher: Aerosol release (15s) 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.
