The new modular energy storage solution is compatible with TCL Sunpower solar panels and offers a capacity of 10–30 kWh, multiple inverter options and enhanced safety features.
Chinese manufacturer TCL SunPower Global, part of TCL Technology Group Corp, has introduced a new all-in-one residential energy storage system (ESS) in France under the SunPower brand. The solution combines solar energy generation, storage and energy management, with the aim of enabling households to increase their own solar energy consumption.
The system is fully compatible with SunPower photovoltaic modules and is managed via the SunPower mobile app. It is designed to help users maximize self-consumption. It will be available in January through five authorized distributors: Alliantz, Ecostal, Génélios, Ned and Voltanéo.
“This new product is a strong selling point for our installer partners: a trusted brand, a complete system and a single point of contact,” said Steven Beaufrère, France Director at TCL SunPower Global. pv magazine France at the stand of one of its distribution partners during the Energaïa trade fair. “In the single-phase version, two inverter options are available: 6 kW and 10 kW. For three-phase systems we offer 10 kW or 13 kW.”
The storage system can be configured in both DC and AC coupled setups and is built around stackable 5 kWh modular batteries. Homeowners can start with a minimum of 10 kWh and expand the capacity to 30 kWh if necessary. Each 57kg battery features ergonomic handles and the plug-in modules with routed connectors reduce manual wiring by approximately 75%, the company said. Commissioning is done on site via smartphone, using predefined standard settings.
The SunPower ESS comes with a 10-year warranty and meets current safety standards. Each battery integrates eight thermal sensors that automatically activate protection mechanisms in the event of overheating, along with fire-retardant airgel insulation around each cell. If a fault occurs, an internal fire suppression system is activated within 15 seconds to absorb the heat and stop thermal reactions. Intelligent algorithms also optimize charge status to extend battery life.
“We also want to support installers by helping them complete the necessary documentation. And because this is new equipment they may not be familiar with, we assist them during their first installation to ensure everything is done correctly,” says Beaufrère.
